Apparently, everyone will never want to catch such terrible troubles. Thus, we need a pair of glasses with computer lenses when working with computer.

Generally speaking, there are two kinds of computer lenses in optical stores, namely, the Plano computer eyeglasses and the prescribed computer eyeglasses. For you guys who have genetic lottery to possess healthy eyesight, Plano computer lenses are recommended. Plano computer lenses have no prescription, just protecting your eyes from harmful ultraviolet ray. For me and for those with loathsome vision problems, prescribed computer lenses are better. Prescribed computer lenses are specially designed for people to see the computer screen which is 23 or 28 away from us. It is totally different from our progressive or bifocal eyeglasses.

Most of office worker have the habit of nap and they use to nap on the desk after the lunch. They would like to use their hands to take place of the pillows when they are napping in the office. The expert have pointed out that napping also need to talk about science. Sleeping on the desk will affect your health, especially the impact of the eyes.

One of the eye experts indicates that there will be a temporary blurred vision after napping on the desk, because the eyeball was oppressed. It will damage your eye vision if you often sleep on the desk. Your eye ball will be enlarged and your eye axis will be longer, which will cause serious myopia as the increase of the time. Therefore, people who have suffered from pseudo myopia, myopia or contact lenses eye wearer should pay high attention to this habit.  You should try your best do not napping on the desk for a long time everyday. If you feel blurred after wake up, you should not use your hands to rub your eyes.  You should stand up to see far for a while.

The eye doctor also told us that desk nap also can affect blood circulation and nerve conduction because of the press of the arm and head. It can easily cause numbness and painless of your arms.

Why people suffer from astigmatism? There are multiple reasons that give rise to astigmatism. The most serious one is that the flexibility of eye cornea changes. Eye cornea is also named” black eyeball” and the window of outward eyeballs. It is thin and smooth and totally is equipped with hemispherical. The main function of cornea is to concentrate on the luminous beam through the light, spurred the light arrive the retina of the bottom of eyes. Then it focuses the light which can be responded to brain and make the clear vision with the outside views. Therefore, as there are some changes with the flexibility of eye cornea, the cornea will like the uneven lenses. When the outward light comes into eyes, it can not form a focus normally but spread out to all directions. Accordingly, our brains take over the uneven light and also reflect the vague sign. Medically speaking, the symptom of irregular astigmatism and changes of flexibility of eye cornea are hardly to be corrected with normal eyeglasses.

There is another regular astigmatism which results from the flexibility of eye cornea. There are many kinds of astigmatism cases include hyperopic, astigmatism, myopic astigmatism, compound hyperopic astigmatism, compound myopic astigmatism and amongstothers. They are major caused by diverse with the capability of diopters and always along with the myopia or hyperopia which can be rectified by eyeglasses.

The reasons lead to irregular astigmatism is uneven light on the cornea or the incorrect direction with the flexibility which can be divided into two sorts: The first sort is congenital defect and the other involves in the diseases which caused by cornea, such as ulcer with the cornea or traumas.

The regular mild astigmatism will have no influence with the vision expect for some eyestrains as well as discomforts. Some people will feel headache or sore around eyes, the minorities have nauseas and vomiting symptoms which will have some effects on their normal life and work, it means they have suffer from the serious astigmatism and should take a treatments at once.

If you think that office clerks are fortunate to have a good working environment in bright and comfortable rooms, you are wrong. With the popularity of computers used in offices, office clerks are facing afflictions caused by sitting before a computer all day long. Many of them complain that they would always suffer from a painful and sometimes debilitating inflammation in the wrist, arms and hands. In response to requirements from computer users, computer manufactures have to improve the comfortability of keyboards, keyboard trays, computer chairs and so on so forth. And indeed some improvements are achieved and those CTSs, Carpar Tunnel Syndromes, decline.

However, another syndromes are found recently. It is CVS, the abbreviation of Computer Vision Syndrome, which are related to visual problems. Because computer users have to spend long time staring at the screen, they often come to syndromes, for example, eye strain and red eyes. Nevertheless, the good news is that CVS can be prevented as well. Dr. Larry K. Wan has filed several tips which work well in CVS prevention, and they are:

Tip 1: Get your eyes examined regularly every year. Don’t take it a necessary task only for eyeglass and contact wearers who have to renew their lens prescription. To ensure eye health, it is also necessary, especially when you have to use computer frequently. A regular examination allows your optometrist to identify whether you are experiencing a deterioration of vision due to CVS.

Tip 2: Dim your lights when using a computer. When there are bright and strong light from every direction, your eyes are very likely to suffer from eye strain.

Tip 3: Use eyeglasses with anti-reflective coating and LCD monitor. Computer is a radiation emitter. Radiation are rather harmful for body and eye health. Eyeglasses coated with anti-reflective coating are supposed to resistant them and possible glare, on the other hand, LCD monitor is supposed to minimize the radiation.

Tip 4: Adjust the brightness of your computer screen. Out of the similar reason mentioned in tip 2, bright light causes eye complications, and at the meantime, dim light is no good to eye health as well. Therefore, reduce or increase the brightness until you find it is comfortable for you to stare at the screen.

Tip 5: Remember to Blink. It is researched that when staring at a computer screen, we are tend to blink less than we normally do. To keep eyes moistened, blinking would provide enough tear.

A cataract is a clouding that develops in the crystalline lens of the eye or in its envelop, varying in degree from slight to complete opacity and obstructing the passage of light. If not treated timely, it may degenerate into incapacity in viewing, that is blindness. Therefore, when you find you are a cataract patient, going for the doctor and undergoing a surgery is a wise decision. To treat cataract, the clouding lens should be removed and a new one should be implanted.

There are formerly two types of eye surgeries that can be used to remove cataract: extra-capsular and intra-capsular. The former one is to remove the cataractous lens and replace with a plastic one while the latter is to remove the lens but leave the majority of the lens capsule intact. Recently a technique called phacoemulsification is applied in the cataract surgery. One of the biggest advantages is that during the procedure, a minor incision will be created to break the clouded lens into small pieces. These pieces are emulsified and sucked out by same ultrasonic probe. A thin outer shell still covers the eyes after the pieces are sucked out. And foldable artificial lens which is made of silicone or acrylic is inserted. This is done by using a proprietary insertion device. This incision does not require stitches and seals by itself.

Usually, before a surgery starts, the doctor will ask the patients to choose proper lens that will be inserted. Monofocal lens is for distant vision assistance, and for close vision, the patients has to wear reading glasses. However, new technology brings about focal lenses and multi lenses that are able to hand distant, near and in between vision. That is to say, with those lenses implanted, the patients would get a clear vision again.

The whole procedure will be done with a local anaesthetic, so the patients would feel no pain, and they can go home in about two or three hours after the surgery. Phacoemulsification is now considered to be an ideal way to treat cataract.

There is another method of surgery called extracapsular surgery which is on its way out. In this method the incision would be 8 to 10 mm and requires stitches. And patients are prone to distortion of the curvature of the cornea, resulting in astigmatism.

To know the Age-related macular degeneration(AMD) well, let’s have a general idea of the macula first. It locates in the center of the retina, which converts light or an image into electrical impulses and then sends these impulses, or nerve signals, to the brain. Therefore, we may know macular plays a fairly important role in viewing. Then age-related macular generation is an eye disease associated with aging that gradually destroys sharp, central vision, the macular. There are two different types concerned, the wet ones and the dry ones. The former is a less commonly seen condition. Wet eyes may quickly develop into blindness, because rightly after the blood vessels behind the retina start to grow, they are very likely to get ruptured. The latter is featured with blurred vision and sensitivity to light. With treatment, it is reversible.

In spit that AMD is age related, however, there are ways to prevent its degeneration and even occurrence. Therefore, having a healthy life and diet style is rather important. Tobacco is one of the arch-criminals of the development of AMD, so to keep away from tobacco is necessary. Eating more fruits and vegetables should be on your dinner table everyday. In addition, salt-water fish and leafy green vegetables are most recommended, for they perform well in AMD prevention. Lack of exercise and obesity are two risk factors contributing to AMD. Besides, to guarantee eye health, regular eye examinations should be taken. They could help in avoiding the worst symptoms of macular degeneration.

If you unluckily suffer from AMD, don’t worry, there are devices which would help in viewing in daily lives. Bioptic glasses are one such device. With miniature telescopes mounted on, the patients are able to concentrate on activities that require acute close central vision. Bioptic glasses work similar to the bifocals we know. For those patients who have a requirement to work with computers, another device, a special monitor that magnifies on-screen font sizes is ideal choice. Wearing them on, the patients are thought to be able to read more easily.

AMD is not terrible. Once you find hard to read, watch TV or do other routine activities, go for an eye doctor immediately. They are always there providing your treatments and advices. Moreover, the National Eye Institute is conducting and supporting a number of studies to learn more about AMD. It is believed that more progresses on treatments for AMD will be achieved.

Eyes are to view objects, however, it is not a born in ability. Our eyes have to learn how to function. The infancy period is a formative time when the infant’s neurological system is very flexible, and can easily adapt to changing environment stimuli. It is during such a period of time our eyes get visual stimuli and learn how to view. If any one of the eyes can not get adequate visual stimuli, amblyopia eye or lazy eye that we usually refer to could be developed. Amblyopia is a kind of eye disease whose symptom is reduced vision.

As one grows when his/her flexibility of the visual system decreases, it hard for him/her to improve the eyesight dramatically. In the past, the doctor would advise the patients to let the lazy eye work harder by patching the better eye, so that the visual function of the lazy eye can be stimulated. Nevertheless, if the patient is young enough, it may in some degree works. that is to say, it serves little when one reaches a certain age. Vision Therapy(VT) is also applied to retrain the visual system to function correctly. Most people would get their vision improved as long as VT is done properly.

Recently, researches find that the antidepressant medication Prozac is able to restate ocular dominance plasticity in adulthood. Such a discovery brings hopes to older individuals who want to promote their visual impairment, resulted from lazy eyes. Such an issue has ever been published in the Science Magazine, reading that Prozac, a kind of antidepressant medication reopens the critical period of plasticity in the visual cortex, and Lateral Geniculate Body parts of the brain. The Prozac achieves it by reorganizing the neuronal connections in the cortex. In the Magazine, the researches have also explained the possible side effect of Prozac’s performance in lazy eye treatment. They should be originated from the long use of drugs, including suicide, severe anxiety, glaucoma and visual filed defects.

Up to now, this study has been only proved to effective in the rats experiments, so further experiments on human being should be done to make sure its effectiveness. Therefore, long term research needs to be done to determine the risk and benefits of such treatment, and improved should be necessarily made.

Macular degeneration is one of the common age related eye diseases. There are a large number of aged people suffering from low vision caused by macular degeneration. The following will give some introduction on the causes, symptoms, and macular degeneration devices to help people maximize the remaining vision, read ahead.

If we want to learn about macular degeneration, we should know macula first. The macula is located in the center part of the retina, which is in charge of the detail vision, such as reading, knitting, driving or other daily tasks. If there is damage to macula by bleeding, a thinning of the tissue, or even a wasting away of the tissue, people will suffer from macular degeneration and can not see detailed information clearly. At the beginning, people may suffer from slight vision loss, if left untreated, finally people may suffer from blindness. Therefore, we can see it is important to have our eyes tested regularly in order to find out the eye problem and treat it in time.

One of the common causes for macular degeneration is due to age factor. When people are at their 40’s or 50’s, the macula will become weak, and they will have a low central vision. Another cause is the family history, which means if there are family members who have macular degeneration, the other members may also have this kind of eye disease. Besides, there are some people who have the genes which can put them under the risk for developing macular degeneration. For example, people who have high cholesterol, or high blood pressure will be more likely to develop macular degeneration. If we find we have blurred vision or part of vision loss, we should visit our eye doctor immediately to do a complete eye test.

In order to take some precautions for age related eye diseases, we can have some food rich in beta-carotene and Vitamins like lutein and zeaxanthin, however, this can not treat macular degeneration. Instead, we should use some new drugs which have a good effect in resisting against macular problem. Moreover, we can also resort to some devices for help. The aim of the devices is to maximize our remaining vision and help us to see detailed information clearly. Take the telescopic lens as an example, there is a tiny telescope on the lens, when we need to see detailed information, we can look through the telescope lens which can magnify the information, and for other works, we can just look through the prescription glass. It works just like bifocal reading glasses. There are various devices available for macular degeneration, and we can choose the most suitable one according to our eye condition and eye doctor’s advice.

Macular degeneration is a common eye disease among elderly people. When people have macular degeneration, they will have some loss in their central vision. So the most important thing to do is to find out the way to save their existing vision. Macular degeneration will offer the very help they need. The following will give some introduction on macular degeneration devices in order to help people to benefit more from them.

When people are at their 40’s or 50’s, the macula, which is located in the center of the retina and in charge of the detail vision, will become weak. Therefore, people will have difficult in reading, playing cards, driving or other daily tasks. If macular degeneration is not treated in time, there will be more vision loss. Macular degeneration devices are used to maximize people’s remaining vision by the use of specially designed eyeglasses, computer programs and other technologies. With the help of those macular degeneration devices, people’s low vision can be improved to some extent, and they are able to enjoy reading or some daily tasks.

Bifocal reading glass is one of macular degeneration devices. With the help of bifocal reading glasses, people can see clearly no matter far away or close up as this kind of glass can change people’s vision field. Therefore, bifocal reading glasses are very popular among aged people worldwide.

Do you know there will be miniature telescopes on the eyeglass lenses? Yes, a miniature telescope can be placed behind or on top of the lens, so in this way, people can have two options. One is to look through the regular lens and benefit from the eye glass prescription, the other is to look through the telescopic lens to see detailed information clearly as there is an ultra magnification.

And for people who have macular degeneration but need to use computers, they can have specially designed monitor for help, as the monitor can magnify the front size and enable people to see clearly. Besides, there is also software for macular degeneration devices, which can transfer our sound into text. We can speak to the computer microphone, and then the sound will be transferred into text on the screen. Moreover, even people with no vision, they can also benefit from the program which can turn the test into Braille documents online.

Closed circuit television is also proved to be an effective macular degeneration device. We can put the right page under camera, and then the image will appear on our television screen, so that people can read and see them clearly.

Thanks for the great help given by macular degeneration devices. No matter what need you have caused by low vision due to macular degeneration, you can always find a satisfied macular degeneration device to satisfy your needs.
