Understanding Eye Anatomy – Function Of The Iris

The eyes are described as the windows of the soul. Along with the many things that our eyes enable us to do which include the ability to perform many different daily activities of a visual nature, our eyes also enable us to communicate with others in a non-verbal manner. For example, there are certain expressions that are conveyed by our eyes that indicate various feeling associated with joy, happiness and sadness. A scientific research study also disclosed that people who maintained good eye contact with others were perceived as confident, attractive and positive. Here are some interesting facts about the eyes that you will find amazing and a little bit crazy. The first blue eyed person experienced some 6,000 -10,000 years ago. Before that particular period of time every one had brown eyes. A psychologist once worn glasses that reflected images so that these images were seen upside down. After 8 days his brain corrected the images thereby allowing him to see them right side up in a normal manner.

The eyes consist of 3 different layers called the sclerotic, the choroid and the retina. Inside of the choroid are various parts of the eyes which include numerous tiny blood vessels, the pupil, the ciliary muscles as well as the crystalline lens. The part of the eyes located behind the crystalline lens is called the iris. The small black circle in the center of the eyes is called the pupil. The iris can be described as a disc of colored tissue that gives the eyes its color. Therefore, the iris is the colored part of the eyes. When the iris is exposed to bright light the iris expands causing the pupil to become smaller. Therefore, the main function of the iris in eye anatomy is to control the amount of light that enters the eyes. This part of the eyes is also responsible for sharpening the image that falls on the retina of the eye.

There are 2 elaborate sets of muscles that surround the iris itself. The first set of deficicate muscle fibers that resemble spokes are responsible for pulling the pupil open. This biological action happens when the eyes are exposed to dark light situations. The second set of ring likeicate muscle fibers are responsible for closing the pupil. This biological action takes place when the eyes are exposed to bright light. These muscles ensure that the image cast on the retina is clear and sharp at all distances. Therefore, one of the other primary functions of the iris is the fact that it plays a role in the process of accommodation which is defined as the action of the muscles in the eyes that enable us to see near and distant objects clearly.

It is a fascinating subject to explore the functions of the different parts of the visual system in eye anatomy. Each individual part of the eyes has a unique function and works together collectively to help us see clearly. To keep our precious eyes healthy we need to give them the proper care so that the visual system can serve us well. Eye exercises enable our visual system to function efficiently and more naturally, thereby ensuring that the different parts of our eyes function at optimal levels. Ultimately, these eye exercise techniques help us to do the things that we need to do to increase our vision health for years to come.

The first layer is called the outer layer which is the sclerotic. This part of the eyes is transparent in nature. In the center of the Sclerotic is the cornea. The cornea is known as the clear thin film that is found in the front surface of the eyes. The role of the cornea is to receive light reflected off of objects focus that light and transmit it to the retina. The second layer of the eyes called the choroid is made up of numerous tiny blood vessels and it consists of the iris with the pupil in the center of it. These tiny blood vessels carry blood circulation from one part of the eye to the other. The crystalline lens is located behind the iris. The role of the lens is to focus light as it passes through the pupil and focus this incoming light on the retina. The choroid also comprises of the ciilary muscles. The third part of the eyes is called the inner layer which is better known as the retina. The retina is a thin layer of tissue that lines the back of the eyes. In the center of the retina is the macular (the part of the eyes responsible for visual acuity (sharper eyesight). light images to the brain via the optic nerve where the brain interprets that image and converts it into the vision that we see. This region of rods and rods and cones. The rods are responsible for visual acuity (sharp eyesight at night), while the cones are responsible for color perception (brighter colors in the daytime). Without the retina all of the other parts of the visual system would not work properly and our vision would become completely dark.

The eyes are without a doubt one of the most fascinating organs in the human body. Due to the fact that they serve such an essential role in our everyday lives that they require care to function efficiently and serve us well in our everyday activities which are all visual in nature. From this point of view, the pursuit of an eye exercise program can help to keep all of its various parts working together in tip top shape. The eyes have blood vessels and eye muscles that play a role in the function of the visual system.

Many skeptics in the traditional eye care industry claim that eye exercises are not scientifically proven or ineffective. However, the truth is that eye exercises do work and there is evidence to point to this fact in the journal of the academy of ophthalmology.

Your Job And Your Eye Health

Doing the things that we need to do to keep our eyes healthy in the workplace environment is something that we rarely think about. A lot of people work in environments that require a lot of computer work. If you work in an office situation there are things that you can do to protect your eyes from the negative effects of poor posture and excessive computer work. Therefore, here is some information concerning what you can do to protect your vision health in your job situation:

It is rare that we ever associate posture with eyesight. However, there is certainly a connection between this factor and the maintenance of healthy eyesight. This is due to the fact that poor posture can lead to tension in the back, shoulders and neck. This can lead to problems in the visual system related to eye strain; one of the factors that contribute to poor eyesight. Also, most people have jobs that require them to sit at their work desks for long periods of time in one position. Often, this is done while clicking and performing work duties that require a lot of close up work. Therefore, if you are in such a workplace situation practicing proper posture will have a positive effect on your eye health.

Here are some tips to maintain proper posture at your work desk to improve your vision health: Sit with your pelvis positioned in such a way that it is pushed back in the seat where it Touches the back of your chair. Sit upright in such a way that your back is in a straight position with your body weight resting on your pelvis. Your back and pelvis should form a 90 degree angle. Also, ensure that your knees are at a 90 degree angle with your feet planed firmly on the floor. Resist the temptation to tuck your feet underneath your chair. This posture releases stress and tension in the back, shoulders and the spine. This allows the free flow of circulation to various parts of the body, including the visual system. Therefore, it benefits eye health.

Sitting at your computer desk all day in one position for too long a period of time can lead to circulation problems and tension in various parts of the body. You can solve this problem by taking a short break from your desk to walk around your office. This will improve the body's circulation; a factor important in improving vision health.

The problem of performing excessive close up work on the computer is that it places added strain on the visual system, thereby causing tension in the eye muscles. You can practice a simple eye relaxation technique involving looking at distant objects to treat eye strain. For example, focus on objects in the distance that are about 20 feet away from you for every 25 minutes for about 5-7 seconds. Glance at these objects in a relaxed manner but do not exert a lot of conscious effort at focusing on them. These techniques release stress and tension in the visual system and relate eye strain. By practicing these relaxation techniques, you'll be well on your way to improving and protecting your precious eyesight at the work place.

Benefits of Daily Disposable Contact Lenses

Are you or someone someone you know finding it challenging to find a contact lens that is comfortable, safe, and convenient. If so than this article might be for you. Daily Disposable contact lenses are contacts worn on a daily basis, all day. At the end of your day you can discard the lenses only to replace them with fresh new ones the following morning. These types of lenses have many benefits over other types available on the market and this article will try to delve a little deeper into the extensive list of advantages that they bring to the table.

Before getting to the list of benefits let's first try to distinguish the differences between contact lenses. Traditional contact lenses for instance, can be worn using a recommended wearing schedule for a specified period of time ranging from days to weeks depending on the lens product. Daily disposables are designed to be worn for one day and discarded at bed time and replaced with a fresh pair the next morning. No more cleaning and disinfecting your lenses and no more cases required to store them. It is also important not to confuse terminologies when discussing daily wear and daily disposables. The latter type are worn for a specified number of days, and disinfected each day to ensure sterility. The former, on the other hand, are worn for one day and then disposed of. Fresh new lenses are used the next day.

Okay, now that some of the semantics are out of the way let's move on to the list of benefits that disposable contact lenses offer.

First on the list and possibly arguably the most crucial benefit is the eye health advantage that these lenses offer. Weaning contacts over an extended period of time, even if they are cleaned and disinfected as recommended by the eye doctor, can result in the unpredictable buildup of calcium and protein deposits on their surface. This buildup can result in erratic surface dryness, as well as the potential accumulation of calcium deposits that irritate the inner eye lids. This undesired foreign debris can cause people to be more vulnerable to eye irritation, or even infection leading to temporary discontinued use. For persons with seasonal allergies these deposits only serve to exacerbate the symptoms of the allergy that a person may have.

The second item on the list is comfort. Eye comfort is a must and this is the norm with fresh lenses worn every day. With these contacts you will experience how a clean lens surface can provide superior comfort.

Number three on the list is convenience. With daily disposable contact lenses there is no more need of purchasing and using cleaning / disinfecting solutions in order to maintain them. This valuable time can now be associated towards more important tasks such as reading, improving gaming skills or watching funny cat videos on YouTube. Humor aside, every one's time has intrinsic value and should be a serious consideration when choosing the appropriate contact lens.

Last but not least on this list is cost. Although these lenses may have a higher up front cost as compared to other types, once you factor out the money saved by not buying required care products, as well as the potential costs associated with resolving and treating unwanted eye infections, one can deduce that these are much more cost effective long term.

Although there are many benefits to wearing daily disposable contact lenses it is important to ask your eye doctor about them and see if they are compatible for you. Contact lenses, like shoes, come in various sizes and only your doctor can prescribe the one that best meets your needs.

Understanding Eye Anatomy – Role Of The Retina In Vision Function

The eyes are one of the most interesting organs in the human body. Here are some interesting facts about our eyes that you probably never knew. The human eye can blink an average of about 17 times a minute. This is the equivalent of about 14,280 times in one day or 5.2 million times a year. Also, the eyes are by far one of the most resilient human organs in the body. From this point of view, there are quite capable of healing and repair. For example, it only takes about 48 hours for the eye to repair a corneal scratch. Also, with the proper preventive care, maintenance and nutrition 80% of our vision problems in the world are preventable and even curable. This interesting organ often called the windows of the soul consistants of many different parts. These include the cornea, iris, pupil, lens, retina, macula, optic nerve and the vitreous to name a few. The clear front window surface of the eyes is called the cornea. This part of the eye is responsible for focusing light reflected off of objects onto the retina. The particular part of the eye called the retina plays a major role in vision function. Therefore, here are some of the functions of the retina:

The retina is a thin layer of tissue that is located at the back of the eyes that lines that part of the eye wall. It enterprises of light sensitive cells called rods and cones that are responsible for color perception and visual acuity (sharp eyesight) at night. The function of the retina is such that it takes the image that is formed at the front surface of the eyes called the cornea and processes that image. Then it transmits that image via the optic nerve to the brain. The brain then interpret that image which then becomes the vision that we see. Due to the fact that it is the light sensitive region of the eyes it helps us to see images in various colors including light images and dark images. The role of the retina in the eyes is critical to sight. Take for instance, if you eliminated the retina, or let's say for instance, our retinas suddenly ceased to function, it would be as if we were blind due to the fact that the retina perceives light.Therefore, if you took this vital part out of the eyes everything would become completely dark.

When we think about our eyes we often associate eye function with the function of a camera. Therefore, we can think about the retina of the eye as the equivalent of the film in a camera. So the part of the eyes called the lens and the cornea in camera analogy would represent the focusing parts of the eyes. However, all of the various functions of the eyes would become obsolescent or useless if the retina ceased to function. For example, like a camera a picture can not be processed and produced without the film. Without the film there is no image.

In eye anatomy the retina plays a crucial role in vision function. As the light sensitive region at the back of the eye it takes light images focused by the eye lens and the cornea, processes those images and sends them to the brain where it is interpreted as the vision that we see. One of the critical features of the retina is to help us to see these images in perfect color resolution (bright colors) and sharp visual acuity (sharp eyesight) at night.

In the camera analogy of eye function it represents the film. Due to the fact that it receives light images, records it and translates this light perception through the brain into the vision that we see, it is the most critical part of the eyes, because without the film of the camera (the retina), our brains could not process the light image that becomes the vision that we can see like the picture of a camera.

Caffeine And Your Vision Health

A study conducted by The Centers For Disease Control and Prevention revealed that about 40 million Americans are getting less than 6 hours of sleep per night. This is the equivalent of about 30% of the work In the United States. Therefore, it is not surprising that coffee racks as the most popular drink and the most frequently consumed caffeine in America. If you are lacking sleep and you are feeling the effects of low energy in the morning, chances are the most convenient energy booster is a cup of Joe in the morning. If you need a drink that makes you feel alert and require something that wakes you up so that you are able to easily coast through the rest of your day, chances are a cup of Joe is just what the doctor ordered.

However, while the positive effects of caffeine may give you an energy boost in the morning, and less the likelihood that you are going to feel that tendency to take that early afternoon nap, it is important to consider the negative health effects that this stimulant has on your body. Some of these negative effects associated with excessive caffeine intake include insomnia, an increase in blood pressure, the jitters, anxiety, irritability and heart palpitations to name a few. But did you know that excessive consumption of caffeine is not good for your eyes as well? However, from a realistic point of view, it is certainly easier to pull teeth and nails than it is to convince Americans to give up their favorite morning cup of Joe. Therefore, here are some reasons why you should cut back on your consumption of this popular drink in order to safeguard your general health and your eye health as well:

According to statistics Americans rank number one in terms of their consumption of coffee and caffeine in the world including lattes, cappuccinos, mochas etc. Considering the fact that the main health problems associated with Coffee come from excessive consumption of caffeine, it is important to determine what is considered a safe amount to consume as opposed to what is not. According to health experts, drinking 4 cups or more of coffee a day is too much and causes harmful health effects. A safer consumption of coffee is considered to be no more than at least 2-3 cups of Joe a day. Therefore, here are some of the harmful health effects of consuming too much coffee a day:

Effects of Caffeine on The Eyes: the short term effects of Caffeine consumption include an increase in blood sugar levels that can cause blurry vision. This blurry vision can often be accompanied by eye twitches. The negative long term effects of excessive Caffeine consumption are much more serious. As research suggests long term over-consumption of caffeine that is equivalent to about 4 or more cups of coffee a day can lead to the development of Glaucoma; a serious eye disease associated with high pressure in the eyes that leads to blindness.

According to the Mayo clinic an over-consumption of coffee can cause the following negative health effects: insomnia, restlessness, irritability, a fast heartbeat, nervousness, an upset stomach and even muscle tremors.

Higher Risks for Heart Attacks among Young Adults with Mild Hypertension: A study conducted by Dr. Lucio Mos revealed that young adults who already had mild hypertension had 4 times the risk for having a heart attack when they drank the equivalent of 4 cups of coffee a day.

While there are some positive benefits to consuming a cup of Joe a day such as increased energy and a feeling of mental alertness, there is a danger to your health that is associated with over-consumption. Fortunately, if you are a coffee fan, a moderate consumption of caffeine at safe levels will not cause great harm to your health. Therefore, as the saying goes moderation is key to ensuring you get the best positive benefits out of your favorite cup of Joe without all of the negative side effects of Caffeine.

Refractive Error Vision Correction Eye Exercises For Better Vision

Doctors in the eye care industry use certain medical terminology that most of the general population does not understand. In the process of doing your research, you may have come across some of this terminology that defines certain types of vision conditions. One example of a term that optometrists and ophthalmologists use quite frequently is the word refractive error. What exactly is refractive error? Refractive error is described as any vision condition that involves the ability of the eyes to focus light properly on the retina. This condition is often associated with the fact that the shape of the eyeball is such that it does not bend light correctly so that the image cast on the retina becomes blurry.

For instance, in the case of nearsightedness the eyeball is too long and light images do not fall directly on the retina but instead are focused in front of it. In the case of farsightedness on the other hand the eyeball is too short and light images do not focus directly on the retina but instead are focused behind it. Therefore, some examples of refractive error vision problems include eye conditions such as nearsightedness and farsightedness. Another example of a refractive error vision problem is astigmatism. This is due to the fact that in the case of astigmatism, the eyes do not possess a perfectly round shape like a baseball but its shape resembles a football. This abnormal or irregular curvature interferes with the ability of light to focus directly on the retina at the back of the eyes.

Therefore, is there a natural solution that can be considered an effective alternative to glasses, contacts and laser surgery to correct these eye problems? In order for us to see clearly light images reflected off of objects should fall directly on the retina. Refractive error problems such as nearsightedness, farsightedness and astigmatism happen as a result of the continuous buildup of stress, tension and eye strain in the eye muscles as a result of many years of excess close up work. Our eyes consist of tiny muscles called the ciliary and extra-ocular muscles. As a result of the lack of use of these muscles and the resulting accumulation of stress and tension in these parts of the eyes, these muscles begin to lose their normal function. Some of these muscles control the focusing power of the eyes. Some of these muscles also control the shape of the eyes. Eye exercises are effective in correcting these vision problems due to the fact that they do rebuild the strength, flexibility and focusing power of the eye muscles.

You can correct problems associated with refractive error such as nearsightedness, farsightedness and astigmatism by performing a series of simple and easy eye exercise techniques on a regular basis. Eye exercises can improve the process of accommodation. This is called the ability of the eye muscles to change the shape of the eyes so that we can see near and distant objects clearly. These techniques strengthen the eye muscles and improve the focusing power of the eyes; factors involved in the process of natural vision improvement. With a little work with these effective and simple eye exercise techniques, each and every day, you can do the things you need to do to achieve sharper clearer, healthy eyesight without glasses, for years to come.

How Does Drinking Alcohol Affect Your Eyes?

Drinking alcohol can of cause effects to your entire body including your eyes. A low intake of alcohol should not cause you any health problems but drinking alcohol heavily can potentially cause health problems including harmful effects to your eyes.

Here are a few of the effects heavy drinking can have on your eye health.

Pupils

Alcohol can cause slow pupil reactions. It slows down the iris' ability to dilate and constrict. This might not seem to be too much of a problem at first but if you have been drinking alcohol, even a small amount, and then drive your pupils will not react as quickly to oncoming car headlights, therefore dazzling your vision which could cause an accident. So even if you have drunk alcohol and it is under the legal limit for driving and you feel fine to drive, think again about the other effects the alcohol is having on your vision.

Vision

Drinking alcohol can not only affect your pupils but also your general visual performance, especially if you have been drinking heavily. The alcohol can weaken the eye muscles which can cause caused or double vision and also can cause delayed reactions.

Peripheral Vision

Not only can your general vision be affected after heavy alcohol consumption but your vision vision can change. Alcohol can sometimes lower your peripheral vision sensitivity and this can give the sensation of tunnel vision.

Contrast Sensitivity

Another way alcohol can affect your eyes is by making them less contrast sensitive. This means it can be harder to tell the difference between shade of gray.

Eye Lid Twitching

Eye lid twitching can be caused by many factors and one of these is a high intake of alcohol. If you suffer with eye lid twitching and drink heavily, try to lower your alcohol intake and see if your eye lid twitching improvements.

Eye Dryness

A study carried out by the Hallym University College of Medicine stating that drinking alcohol, even a small amount, reduced tear breakup time and induced tear hyperosmolarity which in turn can result in eye dryness.

Optic Neuropathy

Optic neuropathy can also be caused by consuming alcohol in excessive amounts. It can cause loss of vision which is typically painless, lowered peripheral vision and issues with seeing and distinguishing colors. This is an ongoing condition which gets worse as time passes and is much more serious that the ones mentioned above. If you suspect you may have optic neuropathy or any eye concerns relating to alcohol consumption you should get an appointment with an ophthalmologist, who can carry out a thorough eye exam.

Eye Appearance

Apart from the effects alcohol can have on how your eyes work, it can also alter the appearance of your eyes. Drinking alcohol can make the blood vessels in your eyes dilate which makes them look very red, and long term heavy drinking could cause this to be a lasting effect.

Migraines

It has been shown that, in some people, alcohol can start off migraines or severe headaches. If this happens you can initially suffer with a visual aura at the start of the migraine or headache, which is temporary but can be visually debilitating causing blind spots or light patterns in your vision.
