The Proper Glaucoma Treatment

Glaucoma is really a degenerative affliction that left unattended leads to irreversible harm to the optic nerve causing sluggish vision loss and also loss of sight at the end. Destruction of the optic nerve because of glaucoma is frequently thought on by amplified intraocular force (IOP). Very clear liquid, identified as aqueous, moves about the eyes in an effort to deliver nutrition towards the damaged tissues and puts tension helps maintain the contour of the eyeball.

Eyesight loss due to glaucoma is simply forever, but you can stay away from early detection and therapy. A glaucoma treatment is normally a long-term process which needs frequent tracking and constant therapy. Because there is not a way to determine if glaucoma is in hand, depending on how someone feels, a Dr. has to be kept.

Healing concentrates on lowering the tension in the eyeball for preventing neurological injury. Eye drops can be used to like a glaucoma treatment although, can be extremely costly, have uncomfortable side effects, and may be taken 'till the end of his / her life. In the event that non-surgical approaches do not minimize tension, surgical treatment may be needed. Various methods are selective laser beam trabeculopathy, peripheral iridotomy, or perphas trabeculectomy.

Open-angle glaucoma appears as soon as liquid boosts production or even decreases the release of fluid, harming the optic neural fibers and slowly and gradually causing peripheral (side) eyesight loss. Aqueous comes from the eyeball over the trabecular mesh close to the side of the iris. In the event the trabecular reticulum is hindered, reducing water flow and drain, the force within the eyeball springs up.

A number of medical experts recommend various things that could avoid starting off a glaucoma treatment and various nasty eyesight illnesses: looking right in the sunshine is definitely a not-to-do issue since the Ultra violet may bring serious harm to your eye. One more thing that will help you have healthy eyes and also a clear eyesight would be to always stay spotless and also never ever mess with them, never apply eye-drops unless your doctor recommends it and also do not start a glaucoma treatment with no health advice.

Like other diseases, glaucoma could have been treated in two simple ways: surgical treatment or occasional medications. Most patients begin with medicines if the syndrome is not very advanced – consultations should be done regularly to find out if they had results or no and also to decide if surgical procedure is really required. There's an array of tablets that you need to take and in many cases you may also be required to combine them in different ways. Glaucoma is really a major disease and should be taken care with very careful attention since the effects are damaging and also everlasting. Beforecoming a glaucoma treatment you must first seek advice from a dedicated eye medical doctor.

Why Cupid Might Need LASIK

According to the latest reports from the United Nations, Interpol, CIA and FBI, Cupid is seriously missing in performance. The god of love keeps up with the wrong people, holding the right ones apart and arranging marriages that too often end in divorce. While the precise reasons for the alarming decrease in Cupid's performance are unknown, the leading international jurisdictions suggest that it might have something to do with Cupid's eyesight. So, it has been recommended that Cupid seek LASIK surgery as soon as possible so he can start shooting his arrow at the right people.

How LASIK Might Help Cupid

LASIK surgery helps improve eyesight by correcting the shape of the cornea. As a result, light rays pass through the corneas and onto the retinas correctly. The ultimate result is clear, sharper images. The improved ability to see his targets will be indispensable for Cupid, who often has to locate lovebirds in the most hidden, romantic places. This will help Cupid shoot his arrows precisely and in a timely fashion to light the fire of passion in lovers' hearts and keep them together forever.

Other Options for Cupid

In addition to LASIK, Cupid might also consider other forms of laser eye surgery, such as Epi-LASIK, LASEK and PRK. Epi-LASIK and LASEK are similar to the LASIK procedure in that the laser energy is not applied directly onto the cornea. Instead, a tiny flap is created in the eye to expose the underlying eye tissues. While LASIK requires the creation of a corneal flap, the Epi-LASIK treatment and LASEK procedure involve a thinner (epithelial) flap. Which procedure is the best for Cupid can be determined only after a detailed, personal evaluation.

If the initial evaluation reveals that Cupid has thin corneas, he might not be a candidate for LASIK, Epi-LASIK or LASEK. However, he may still be able to undergo PRK, a laser eye surgery procedure that does not require the creation of any type of flap. Instead, during PRK the laser energy is applied directly onto the eye's surface.

Maybe Cupid Needs Cataract Surgery?

While this issue has not been publicly discussed due to its sensitive nature, it may be that Cupid's eyes have cataracts-a cloud of the eye's natural lens that typically occurs with age. After all, Cupid has been around for thousands of years and he's not a spring chicken anymore. Fortunately for Cupid, this problem can be solved rather easily by changing his cloudy lenses with artificial lens implants during cataract surgery. Within a few weeks after surgery, Cupid will be able to see clearly and shoot his arrows at the right targets. Who knows? Perhaps this will lead to a decrease in the divorce rate and an increase in the number of blissful couples worldwide.

Improve Your Contact Lens Wear – 5 Top Tips to Help You Get Clear and Comfortable Contact Lens Use

I can remember way back, when my contact lens patients would come into my consulting room, having had the same pair of contact lenses for the past 12 ~ 18 months and wondered why the lenses felt 'gritty', 'dry' and 'misty' . My reply would often be that the lenses had reached the end of or in some cases exceeded their natural 'life'. Of course, the lenses do not actually 'live' as such, but an old contact lens would produce the previously mentioned problems due to deposition of proteins on the surface of the lens, which would also limit the amount of oxygen rich air to pass through to the cornea, causing unseen (to the naked eye) damage to the patients corneal health. Thankfully, times have changed, along with disposability and more importantly, manufacturer's endeavors to create contact lenses that maintain comfort and health for longer daily wearing times.

This, my first of many articles, will highlight some areas that new and old contact lens wearers alike, can benefit from some very easy, yet invaluable advise on getting the most from their contact lenses, be it daily / two weekly or monthly disposables. So sit back and take in my 5 top tips on improving those lovely little bundles of clarity!

  1. First and foremost, make sure that at your initial visit to your Opticians, you give the Contact Lens Optician as much lifestyle information as possible, for example, if you work in a warm / air conditioned environment, let the professional know, as this will dictate the type of contact lens that will be provided for your trial. If your visit is for a routine aftercare appointment and your wearing times / environment or medication (if you're taking any) have changed in any way, then the specialist will be able to use a more suitable material to help combat any comfort problems that you might be experiencing.
  2. Never overwear your brand of contact lens. By this I mean not just daily wearing times (or overnight wear if your using an extended wear contact lens), but the use for time, ie do not wear a daily disposable more than once or try to get that extra day out of your monthly disposables. They're called these names for a reason you know!
  3. If your contact lenses are reusable, then use the solution that your eyecare professional has recommended and do not swap / mix brands before seeking your optician's advise as some solutions may not be suitable for your type of contact lens or even for you, especially if you have a history of allergies.
  4. Have you considered using supplementary comfort drops to help maintain your contact lens moisture for the duration of your wearing times? This is a great way to help keep your contact lenses comfy, clear and a joy to wear! Such brands as Alcon's 'Optifree rewetting drops' or AMO's 'Blink' are great BUT make sure that the drops say in the instructions that they are suitable for soft contact lens use.
  5. Finally, you may have worn a particular brand of contact lens for some time without experiencing one of the new breed of Silicone Hydrogel materials. “What's that?” you're probably thinking. Well, Silicone has been around for quite some time, originally in the 1970's, but there were problems with those early prototypes and they were dropped in favor of Hydrogel (waterbound polymer) materials. Hydrogels of high water content were seen as the savior of long wearing times but we eventually realized that they too had a set of problems, not least the fact that they made the wearer's eyes very dry, so after years of research Bausch & Lomb released the first Silicone Hydrogel lens called 'Purevision'. It was great, we had a lens which breathed nearly 4 times as much air through to the cornea than that of a standard Hydrogel lens, without the factor of drying, due to the silicone element.Nowadays, all the major manufacturers have adopted Silicone Hydrogel as the material to use, so my final tip is to try one of these new breed of lens, such as Cibavision's Airoptix Aqua range, Coopervision's range of Biofinity, Bausch & Lomb's Purevision or Johnson & Johnson's Advance / Oasys / Trueye. They're really comfortable, they reduce dry eye symptoms, wearing times are higher and in some cases can even be worn over night (check that you are qualified with your eyecare professional first). You should be able to get a free trial from your optician as a way of allowing you to try them before you switch over. So, there we have it, some top tips to help with making your contact lens wearing a bit more enjoyable, because they are there to be enjoyed. Remember though, if you do have any problems that you're worried about regarding your contact lenses, seek out the advise from your eyecare professional and get them to check everything over.

Why Does Corneal Thickness Affect Lasik Eye Surgery?

One of the key measurements in the preoperative evaluation of Lasik eye surgery is the patient's corneal thickness. The cornea is the clear dome which forms the front of your eye. It functions as a lens and accounts for about 60% of the focusing power of your eye. Lasik surgery works by using a laser to reshape the cornea and alter its focusing power.

Lasik uses a very particular type of laser called an excimer laser. This laser produces light of a specific wavelength which has very unique properties when it contacts human tissue. Essentially, it causes the tissue to vaporize in a very precise manor with very little thermal effect. In other words, it can very accurately remove tissue without causing any burning so there is no collateral tissue damage. By using a controlled, computerized optical system, this laser light can be direct to the surface of the cornea to reshape it with incredible precision.

Lasik requires that some amount of cornea tissue be removed in order to change its shape. Over the years, eye surgeons have developed generally accepted principles as to reliable safety margins for how much tissue can be removed and how much must remain. It is generally believed that if too much tissue is removed from the cornea that its structural integrity can be compromised and it will be weakened. Any weakness of the cornea can lead to distortions of its shape which are unpredictable and irregular. The weakness may also be progressive causing something called ectasia where a part of the cornea pushes outward.

Everyone's corneal thickness is different and it is an essential part of the preoperative Lasik evaluation to measure it. The most common way to measure the corneal thickness is by ultrasound but there are also a number of newer optical instruments that can make similar measurements. An average corneal thickness is usually in the vicinity of 550 microns but there is a reliably wide variation with some being thicker and some thinner. In some cases, an unusually thin cornea may be an indication of weakness or something called keratoconus. These people should be screened out prior to having Lasik because their corneas are already inherently weak. This diagnosis is made using measures of corneal thickness, corneal shape or topography, and other clinical signs which can often be seen by a trained ophthalmologist at the microscope. Anybody determined by their eye surgeon to have keratoconus should be excluded from having Lasik surgery based on this information alone.

When performing Lasik, the surgeon can only remove tissue to a certain depth. Most surgeons will want to leave a base of at least 250 to 300 microns of untouched cornea for safety. Lasik requires a certain amount of tissue to be used to create a surface flap which is lifted out of the way before the excimer laser removes tissue and reshapes the cornea optically. The thickness of the Lasik flap is critical because the thinner the flap, the more Lasik treatment can be performed before reaching the minimum untouched base requirement of 250 to 300 microns. Again, the feeling is that if the depth of treatment goes significantly beyond that point, that the structural integrity of the cornea may be compromised.

With older technology, a bladed instrument called a microkeratome is used to create the Lasik flap. A typical flap thickness using this instrumentation would be approximately 160 microns. So for a patient with a 550 micron cornea, after creation of the flap, the remaining tissue would be 550-160 or 390 microns in thickness. If the surgeon wishes to leave an untouched base of 300 microns, that would leave 90 microns of tissue to be removed and reshaped for the optical effect. Typically, for each diopter of nearsightedness, it requires the removal of approximately 12-15 microns of tissue. So treatment may only be possible for up to -6 to -8 diopters in this patient.

New Lasik technology is completely blade-free and uses another laser (a femtosecond laser) to create the flap instead of a bladed microkeratome. These femtosecond lasers can accurately make Lasik flaps that are much thinner, around 100 microns in thickness rather than 160 microns. This additional 60 microns leaves more tissue for the optical treatment allowing 5 or 6 diopters of additional possible treatment in an average person. So when using the femtosecond laser systems, higher Lasik treatments can often be performed even in patients with somewhat thinner corneas. It's this important corneal thickness measure as an indicator of risk for corneal weakness which helped to make these blade-free Lasik systems so popular. Because the femtosecond laser can create significantly thinner flaps with such precision, Lasik surgeons have a much greater sense of safety with regard to exceeding more nearsighted individuals.

An Ophthalmologist Is An Eye Doctor

The human eye transforms light into visual reality. It is subject to a panoply of diseases, some minor and some with catastrophic repercussions. The American Academy of Ophthalmology advises early treatment of any disorders. Examinations are important to facilitate this. One eye disease, glaucoma, will cause blindness if left untreated. It deteriorates the optic nerve and is caused by intraocular pressure. It is asymptomatic until in the advanced stages. If detected in time, the progress of the disease can be slowed down by reducing the pressure.

Cataracts are the disorder that affects the eyes by clouding the lens and thus, obstructive clear vision. Normally, they do not cause pain. They develop very slowly and can go unnoticed for some time. Their development can be caused by chemical changes in the lens that normally accompanies the aging process. Others are caused by a genetic birth defect. Still others are the result of trauma.

Macular degeneration is an eye condition in which the center of the retina, the macula, deteriorates and leads to loss of a central vision. It is considered a normal part of the aging process. Eye allergies can occur at any age. They are a reaction to an irritant that makes them itchy and swollen. Amblyopia is also known as lazy eye. It is poor vision in one eye that failed to develop normally during childhood. These are some of the most common eye ailments.

A common eye infection is conjunctivitis. Also known as pink-eye, it is evidenced by infection of the membrane that lines the eyelids and swelling. Causes include bacteria, viruses, exposure to chemicals, fungi, extended-wear contact lenses and chlamydia. This condition is contagious but responds well to treatment.

Symptoms include the formation of crises on the eyelids, blurred vision, itching, redness (as the name pink-eye impressions), sensitivity to light and increased drinking. Eye drops containing antibiotics are the treatment for bacterial conjunctivitis; warm compresses applied to the closed eyes will sooth the discomfort. The family or school can be reinfected without precedences are taken.

You can also help yourself with eye drops such as Stilla or others and use it regularly to help your eyes relax and wet. These kind of drops help preventing eyes infection and also prevent eyes' redness.

For a better hygiene for your very precious organ, please be responsible to go check in at your Ophthalmologist place at least once a year.

Macular Degeneration Symptoms

Macular Degeneration Symptoms

Due to access to physicians, awareness among patients, physician access and major improvements in treatment, macular degeneration is being increasingly commonly diagnosed. As more people get older, there is an increased risk by as much for the condition of macular degeneration and it is a challenge that is formidable to both the doctors that treat it and the society as well since the cost of delivering high quality care increase. Age-related macular degeneration (AMD or ARMD), or senile macular degeneration (SMD – a term that has now been discarded) are other names of this condition.

In this condition, the macula which is a portion of the eye that has the retina is affected by pathological conditions and the central vision is affected. This is the part of vision that one sees directly in front of them as opposed to periphery vision which is the vision to the side. With the deterioration in the retina, the macula or central part of the retina that is used in color and detailed vision, for reading as well for activities like threading a needle, signaling a check or recognizing faces is affected. It is the macula that, as part of the eye and the nervous system, that facilitates human beings to have vision that is 20/20, or something very small like a rodent far below the ground.

Affecting about 1.75 million people or more in the US, macular degeneration is the cause that causes the most number of people past the age of 55 to become legally blind. Due to the increasing population, it is expected that this number will cross the 3 million mark by 2020. It is a major cause for public concern due to an increase in the overall life expectancy.

The two types of age-related macular degeneration are:

Dry (atrophic) form: The breakdown of cells that occurs specifically in the macula, causing the central vision to gradually start blurring and drusen which are round, small, single or multiple spots that are yellow and white in color are the identifiers that are key for the form that is dry. An examination of the eye's retina using lenses that are specifically engineered, an ophthalmoscope or a slit-lamp biomicroscope helps detect these spots that are located in the outer retina at the back of the eye. These spots become visually noticeable when the individual is in their 30s and become more common as they get into their 70s and beyond. It is possible for individuals with these spaces to have no symptoms and excellent vision and this condition starts with the dry form that affects most people and is more common than the wet form, fortunately. Geographical atrophy is a condition where there is an advance in the sensory retina and the change in the nerves that is waste progressively and this is the primary cause of the loss of vision in the dry form of AMD.

Wet (exudative or neovascular) form: Growing under the retina's center, there are abnormal blood cells that are created newly and these bleed, leak and scar the retina thereby distorting the central vision. There may be rapid loss of vision in the wet type of macular degeneration.

* Two-thirds of affected people have loss of vision; however about 15% of people alone with macular degeneration that is age-related are affected.
* There are 200,000 new cases or more of the wet form of macular degeneration that is age-related occurring each year.

Color Blindness Overview, Symptoms and Treatment

Contrary to the name, there are actually quite a small number of people that suffer from color blindness who usually does not see any color in any way. It is rare that a color blind person will only have the ability to see gray, black and white. The majority of people who are color blind will only be warned from viewing specific shades of a color or will realize certain hues as an incorrect color. The most common example of this is someone who mistakes blue for green or vice versa. Others may only see certain shades of the color blue but perfectly see all shades of red. It varies from one person to the next.

Many people who are color blind have inherited this and it exists at birth though it may not be recognized until some time later. If this is actually the scenario, the problem will never be correctable. Neverheless, a lot of people can learn how to effectively live with this vision impairment. Schoolwork might be much trickier for kids and adults may possibly be constrained in their business pursuits.

In some instances, it is often the end result of another issue in the eye such as glaucoma or cataracts. During this situation, in the event the undering issue is rectified, ordinary color vision can normally be restored at the same time.

This takes place when there is a problem together with the three sections of cone cells in the macula that filter red, green and blue hues. If your cone cell is lacking, the person will not see that shade by any means. If something is broken within the cone cell, the particular person might only see specific shades of that color or may interpret that shade as a different for example confusing blue and green.

It will not get progressively worse with time. It requires require configurations to lifestyle as it can not be corrected. Many people that are color blindought to learn to adapt to a variety of other techniques such as memorizing the order of color on traffic lights.

While adapting to this eye condition can be frustrating, it should not be a debilitating disease of the eye. Most people are able to adapt to the differences in how colors are perceived without an issue. Over time, those with color blindness can enjoy the same quality of life as those with normal vision by learning and accepting adaptation as part of the lifestyle.

New Fashion Eyewear Releases for Spring Time

Every year, spring and fall marks the release date of new fashion trends for the year are released by most fashion houses in the industry. Well, the industry for eyewear and sunwear are no different; I just spent several days in New York City viewing hundreds upon hundreds of new releases of eyeglasses and sunglasses. The trend for this year seems to be the larger and more eclectic designs. Larger and bolder plastics for both men and women are the focus for the year in question.

The most recent recession not only affected everyone's bottom line, but it also made the eyewear fashion homes redesign their styles that reflected the downturn in the economy. For the new ladies styles, plastic frames are still the industry standard for luxury but they are no longer embedded with glitz and bling. Fun and funky is now the focus of the ladies fashion eyewear industry and the vehicle they are using to convey that message is bolder and more vibrant colors. You will also see more frames in larger sizes. New sunglasses will have a flair for the late 1980's style with metal inlays on the frame and temple replacing the blingadge from before. Large and bulbous is the new name of the game

Fashion trends for men this year still remains much the same as last year. Bold plastic frames still remain at the top of the charts; chic geek, Clark Kent, chic nerd, Drew Carey, Weezer, retro, and old school are all the acceptable descriptive terms for this look that still dominates the mens eyewear designs for this year.

New luxury designers have arrived on the scene this year have made a big splash. Do not start pulling out your credit card just yet. These new designers comprise precious metals such as solid gold, platinum, buffalo horn, and sterling silver as their materials of manufacturing choices; price points can start as little as a thousand dollars and go as high as four thousand dollars.

So now, let's recap the new spring styles. The new trends and styles for women are bold colors and larger sizes while men's fashion remains the same as before. New women's sunglasses are the retro nuveau from the 1980's with bold colors. These new arrivals are slated to ship within a month or two so make an appointment with your optical professional to see what your new look can be.

Computer Vision Syndrome: What You Should Know

We're a generation of computer and technical gadget users, ensuring that on a daily basis, most of us spends far too many hours glued to screen. This exposure results in poor vision, dry eyes, double vision, eyestrain, tired eyes, sore muscles and headaches which affect anyone, of any age!

The American Optometric Association (AOA) reported that eye doctors in the United States perform around 10 million eye exams each year due to computer-related eye problems. They recently announced that long-term computer use affects children just as much as adults and that people need to really stop and think about what they're doing to their eyes.

Parents should take control of their children's time spent in front of visual mediums and limit their time on them accordingly. Children spend hours on their computers and they also risk suffering from obesity in addition to eye strain.

The new medical term for those suffering from problems related to sitting in front of the computer too much is: computer vision syndrome, or CVS. It's a temporary eye condition that results from prolonged eye focus on a computer display for long periods of time. The symptoms of CVS, fatigue, dry eye, blurred vision, and others can be exacerbated by poor lighting.

Most businesses already know that time is money; but what about computers and a worker productivity? A study released by the University of Alabama at Birmingham (UAB) School of Optometry found that proper vision correction specifically results in higher productivity, and the time it takes for a worker to perform a task. It was found that without proper vision correction, performance on a task could suffer by as much as 20 percent Before, employers should provide their employees with vision care benefits, so they not only boost productivity but also reducing the margin of error made by employees.

Whether for adults or children, proper rest for the eye and its muscles is recommended to relieve dry eye and associated eye strain. Although eye drops are always an immediate suggestion for dry eyes, constant blinking is another. Every 20 minutes, one is also encouraged to look out the window to a distant object or to the sky, or to focus ones eyes on an object 20 feet (6 meters) away for 20 seconds or close their eyes for 20 second every half hour .

Sometimes, simply rearranging your work or computer environment can help to reduce problems related to CVS. Proper lighting is also essential in this regard. You should also become aware of your body and the messages it sends while you are using your computer.

Computer ergonomics helps to increase productivity by optimizing your workstation to reduce the specific risks of computer vision syndrome (CVS), neck and back pain, carpal tunnel syndrome and other disorders affecting the muscles, spine and joints.

The US Department of Labor's Occupational Safety & Health Administration (OSHA) came up with a few basic tips to help in the fight against CVS. We note three of them here:

  • Position your computer display so the top of the screen is at or slightly below eye level. This will allow you to view the screen without bending your neck.
  • Adjust the position of your display to prevent reflections of overhead and outdoor lighting appearing on your screen.
  • Put your monitor close enough to your eyes so you can comfortably read text on the screen without leaving forward.
  • When working with print documents, use a document holder that positions them at the same height and distance as your computer screen.

Those wearing multifocal glasses should be able to comfortably look at the computer BUT if they find that they are suffering at all, then they should look into computer glasses.

You may also need a separate eyeglasses prescription for CVS and the lenses may need specialized coatings. Consult with your doctor before ordering eyeglasses mean for computer usage.

A reminder, no matter how many exercises you do, prolonged computer use is unhealthy for your vision and you should take full regular breaks for 15 minutes once every hour.

Correcting Lazy Eye

Lazy eye or amblyopia is a condition characterized by poor vision caused by the brain's favoritism to the other eye, most often associated with severe farsightedness or nearsightedness. Lazy eye affects mostly infants and toddlers. The eyes may appear normal initially but if not treated at an early stage can lead to blindness or loss of vision in the lazy eye. An individual who has amblyopia can not see things clearly because the problem lies in the pathways between the eye and the nerve. The key to treatment is in early detection and regular treatment.

Early Detection

Having the problem diagnosed at an early stage is the best solution to amblyopia. It is a curable eye disorder and early detection can save the sight of the person. At an early age, children with amblyopia may complain of blurry vision on one eye. This should not be negated as this can be a symptom of the disorder. However, for children who are not of talking age, the symptoms include eye squinting, the eyes are simultaneously at different directions, or the child may tend to cover one eye. As the child gets older, his / her visual pathways becomes more permanent, which generally tend to be at 7 years. Beyond this age, it would be difficult to treat the disorder. More often, children with this condition beyond the age of 7 have less or little chance of improvement at all.

Treatment Options

To correct it, ophthalmologists would require the patient's good eye patched. Patching allows the brain to adjust itself to using both eyes. It may not be an invasive correction option but children normally react adversely to the patch. They find the patch uncomfortable and restrictions their movements. Here, patch should be done at a time the kid is most sober or when not at play or at school, but must be done consistently. Recommended length of patching time is a minimum of 2 hours daily.

Alongside the patch, other options for lazy eye treatment include vision therapy. The use of equipment is customized to the patient which includes prisms, lenses and filters. This technique, however, is not a complete assurance and is quite expensive.

A surgical procedure like LASIK can be done in extreme conditions wherein the problem is associated crossed eye. Prior to the procedure, there are several screening tests to be connected because this operation is a treatment to eliminate the problems.

One of the treatments usually usually prescribed by ophthalmologists is the atropine drops which must be administered under supervision. The medication is dropped into the good eye to dilate the pupil which will cause blurry vision. This allows the brain to use the lazy eye, instead and concentrate on it. However, the method is also debatable as treatment lasts up to 3 days and the side effects that the drops have on the good eye are uncertain.

Parents are encouraged to have their children (infants 6 months old) to undergo comprehensive eye tests checked and at the age of 3. Any disease or disorder, once detected early increase the chance of correction or treatment.
