The main symptoms of CVS are: -
Sore, tired, burning or itching eyes
Watery eyes
Dry eyes
Blurred or double vision
Headache and sore neck
Difficulty shifting focus between monitor and paper documents in your work area
Color fringes or afterimages when you look away from the monitor
Increased sensitivity to light

Many computer users experience visual stress due to:
1) An increase in the number and complexity of necessary eye movements and focusing skills
2) Poor lighting conditions, glare and distracting reflections
3) Screen flicker rate
4) The extended amount of computer use.
Since this a profession related complication, it can be treated with modifying the work area and introducing some alterations in the work habit to reduce the symptoms.
The modifications in the work area are-
The computer screen should be slightly below eye level (about 20 degrees). Copy should be at the same level as the screen.
Wrists and lower arms are parallel to the floor while working on keyboard.

The working chair should be comfortable with a good back support
Sit straight on the chair with feet flat on ground, thighs parallel to ground and back erect.

The screen brightness and contrast should be adjusted by the operator for the maximum viewing comfort
The workstation lighting should provide a 10:3 ratio: screen characters 10 times brighter than the screen background; room illumination 3 times brighter than screen background
Eliminate glare and screen reflections by moving or tilting the computer or getting an anti-glare screen.


Try not to face toward windows or bright light sources
Operators should face into an open space beyond the computer screen
Clean the screen regularly as they attract dust

To reduce the symptoms, there are some alterations in the work schedule that can be done-
Take a break after every 11/2 to 2 hours. Get up from the workstation and walk 20 paces one side and 20 paces the other side. Sit on your chair and close eyes for 3-4 minutes.
Consciously blink your eyes more frequently as the blink rate is reduced with continuous work on computers causing dryness.
Use artificial eye drops for lubricating the eye.
If still symptoms persist, then get an eye examination done to rule out any refractive error. If there is one, then use corrective glasses for the same.

The LASIK procedure utilizes technology to the most. The surgery consists of a computer system keeping track of the candidate’s eye position 4,000 times per second. At the same time, the laser is making precise programmed incisions. This really is not a risky procedure. LASIK eye surgery is a proven safe surgery that provides high and quick results so that candidates no longer are dependent upon wearing glasses or contact lenses. The laser reshapes the corneal tissue on the outer surface of the eye. When LASIK surgery is compared to other corrective eye surgeries such as using a blade to create the corneal flap, the number of complications is very low because of the preciseness and high technology of the laser.

The candidate is awake during the procedure. The candidate is given a mild sedative and numbing eye drops. During the procedure, the pain to the candidate is very minimal. The LASIK has a very low number of reported complications and provides quick and positive visual results. Most patients obtain 20/20 vision within a few months after the surgery. As with any type of surgery, there are risk of complications such as infection, halo effect in the eye sight, dry eye, and irritated eye.

Since LASIK eye surgery uses the most advanced technology, this procedure is becoming very popular. There is no concrete evidence on the long term complications of having LASIK eye surgery.

If you are considering LASIK correction eye surgery to not have to wear glasses or contact lenses, do the research on the ophthalmologist. Have fun not having to wear glasses or contact lenses.

Age related macular degeneration (AMD) affects the central part of the retina, and therefore one’s ability to determine fine details such as print, faces, and images. Essentially, one develops a “hole” in one’s vision; if the subject is looking at an object that appears smaller than this “hole,” the object cannot be seen clearly. Therefore, the purpose of low vision devices is to increase the apparent size of these objects.

Because we use our eyes in different ways in different situations, there is no one solution for addressing macular degeneration symptoms. One patient may require several different low vision products. Bifocal reading glasses are one of the best known and most common low vision devices, but may not be appropriate for all macular degeneration symptoms.

Bioptic glasses for low vision, also known as bioptic telescopes, are low vision devices that actually consist of miniature telescopes mounted atop a pair of regular glasses. Such low vision devices can be adjusted for a wide range of activities that require both distance and near vision. While bioptic glasses for low vision work in the same way (you tilt your head forward slightly), they differ from bifocal reading glasses in that the telescopic lens is not integrated into the primary lens itself.

Other low vision products for age related macular degeneration include such products as the portable digital magnifier, which resembles “virtual reality” goggles and is used in conjunction with a special pair of glasses. One of the most interesting low vision products on the market today consists of a miniature TV camera that actually rests on the surface of whatever the patient is reading, magnifies it, and sends that image electronically, projecting an image on the inner surfaces of eyeglass lenses! Such a system allows the patient’s head to remain in an upright position; no longer is it necessary to tilt one’s head.

Of course, such high-tech vision aids are quite expensive at the present. However, if the history of other technologies such as the PC and the DVD is any indicator, the cost of such low vision devices should come down substantially over the next few years.

Radiation therapy has advanced as well. More sophisticated equipment and technology does less damage to the surrounding tissues. New discoveries and developments have brought about new and more effective medicines with less side effects. This and other advancements have been brought about by ongoing cancer research.

Cancer Research UK is one research organization based in the United Kingdom. It is one of the few independent organizations devoted to cancer research in the world. One of the goals of this organization and others like it is to gain a better understanding of the various types of cancer. By doing so they can then develop better medicines and treatments to fight cancer.

Only through a better understanding of cancer can advancements in these areas be made.Research is the step by step process that is done by collecting and examining data on cancer. It almost always involves a quest for new information that can help to develop a new drug or treatment or hopefully some day an actual cure for cancer.

Research can involve the study of its basic biology to the effects of treatments. Another area of research involves the testing of drugs that have already been developed. Before a drug is made available to the public it must undergo years of testing to make sure it is safe and effective. Right now there are drugs undergoing testing that in years to come will be available for use but researchers must first determine their overall effect on the cancer patients who use them.

Most people don't realize just how many different types of cancer there are, each with its different problems in treating it. So there has to be many different areas of research to develop treatments for them. Cancer Research UK supports over three-thousand researchers and the work they are doing.

The one true key to successful cancer research is money. One ongoing job for nonprofit cancer research organizations is raising the funds to support the work they are doing. Anyone can help cancer research by making a donation to any of the nonprofit cancer research centers. In this way you can do your part to help find better treatments and hopefully some day a cure for the disease.Another way to help is to take part in a clinical trial of a new drug or treatment.

Another area of cancer research is focused on the relieving of the symptoms of the cancer. Until a cure is found people with cancer have to endure the symptoms of the disease. The first one that come so mind is pain but there are many others such as dietary and nutritional special problems cancer patients face.

Learning how to better keep cancer patients pain free, happy and healthy is another area of ongoing cancer research. There too many areas of cancer research to cover here but we have covered a few. Only through cancer research can progress be made in understanding its causes, how to prevent it and eventually a cure.

An eye sty is believed to be caused by some debility in the system. It can even be caused due to blockage of glands by dirt or refraction error. A sty in the eye is usually a harmless development and can be treated at home. Styes may be treated by making a decoction (prepared from the roots, seeds, stems and other parts of the plants that are boiled in water) of eyebright and chamomile, to help reduce the inflammation.

Sometimes, the infection disappears quickly, without forming into a red swelling. But other styes worsen rapidly until the eyelid swells up. Eye stye occurs when staphylococcal bacteria infect one of the tiny glands at the base of the eyelid hairs and then becomes inflamed. It is commonly found as small bumps on the base of eyelids.

Stye is often accompanied with certain complications, such as there may be spread of infection to other eyelash follicles. There may also be spread of infection to the tissue of the eyelid, which is known as Eyelid cellulites. The symptoms of styes may resemble other conditions or medical problems.

Some Eye Sty treatment Tips

1. Do not touch your eyes when you are gardening or cooking.

2. You should protect your eyes from air pollution and dust.

3. You should wear sunglasses before going outside.

4. Take a cup of water. Dissolve 2-3 granules of alum in it. Use as an eyewash.

5. Slit an aloe leaf lengthwise and place the pulpy side on the sore eye.

Scientific evidence has proved that ultraviolet rays can cause damaged to your eyes, The long term effects can lead to Blurred vision, vision impaired, head aches and in some worse cases vision loss.

It's important to cover your eyes with sunglasses that protects you from the UV's rays. Ultraviolet Radiation is invisible and over exposure has shown the risks of developing age-related muscular degeneration. Retinal diseases are the leading cause for blindness and unlike your skin the results are irreversible.

So What age should you wear Sunglasses

The Younger the better, the risk of retinal damage is much greater when your in your childhood. The damage happens over a long period of time and the effects aren't felt usually until your in to your adult years . However with the ozone lays and green house gasses , it's never been a better time than now to start thinking about investing in to some good Quality eye care.

What sunglasses should I get.

Not all sunglasses are the same, and a lot of cheap brands make false claims. A good pair of sunglasses should protect your eyes from both UVA and UVB sunrays. UVA or UV400 = 400 nm the wavelength of UVA radiation (they should block out about 100% UVA rays). And all sunglasses block out UVB sunrays.

Is a darker lens better for protection

Ordinary dark sunglasses can make the effects worse if they have not got protection, the dark lenses cause yours to open wider the retrieve more light, by this your pupils dilate, upon which this allows more UVA radiation to damage the lens and retina in your eyes.

What symptoms should I be aware of

A form of eye damage is loss of transparency in the lens of your eyes, if left untreated this can turn to blindness. Another kind is apterygial, this is tissue growth that can block vision. Skin cancer around your eyes, and degeneration of the macula. Your Options or Doctor would be best to advise you .

All these problems can be avoided just by wearing the right eyewear, Sunglasses aren't just a fashion statement, they are a very important part of every day life. The younger you start to wear them, the better your eye's will be in the future. You should always encourage your children to wear sunglasses.

- A progressive wearing of your contact lenses is needed (from a couple of hours in the first day, to a 12 hours period later on);
- You should avoid wearing them in the week-end or at least one day per week;
- Store the contact lenses in their special boxes and if you have different dyoptrics, be careful not to mix them up;
- Every morning after putting on your contact lenses, throw away the solution in which you kept them overnight and refresh it in the evening;
- Make sure that you always keep your contact lenses in their special solution; if not, they dry and become useless. You must use the special solution that comes with your contact lenses and not some improvised solutions like those with water and salt.

These recommendations are everyday steps that must be followed for a proper hygiene of your contact lenses, but when it comes to going away on vacation you should also consider the followings:
-You must not use any cream soap because the cream will remain on your hands and can be easily transferred to your contact lens;
- After swimming, the contact lenses must be removed, cleaned and disinfected. You must know that not all contact lenses can be worn at the beach or at the pool. The rigid ones can get lost easily; therefore those flexible and soft ones are more suitable for these situations. There are also special contact lenses for swimming, but you should make sure that they are appropriate for this before actually going swimming. You can easily find out if your contact lenses are made for swimming, by diving with your eyes wide open, into a bowl full of water. Move your head around a few times and, if your contact lenses don’t move, then you’re good to go!
- When you get out of the water you have to blink often in order to eliminate the excess liquid from your eyes. You shouldn’t rub your eyelids very hard.

Nowadays, when we can change almost every part of our body that we dislike, our eyes don’t make an exception. We can actually choose the color of our eyes, due to a simple contact lens. Since this option is often adopted by women, being regarded as one of the easiest change-of-look tricks, these women must remember the followings:
- Put on your contact lenses before putting on your make-up.
- If you use fixative for your hair, do it before you put on the contact lenses, and close your eyes while you spray it.
- Keep away the nail varnish, your perfume or the acetone because these can affect the plastic in your contact lens.
- Blink often when you dry your hair so that your eyes don’t get dry.
- Use a liquid foundation cream, so that it doesn’t affect the contact lens.
There are various colors of contact lenses, adapted to everyone’s needs and wishes. You can even get a contact lens for Halloween and for a Vampire look or blank contact lens to make you look blind. You can simply choose a contact lens of a color and another contact lens of a different color for a strange, funny way of looking.
A large variety of colors is offered by acuvue contact lenses. Some acuvue contact lenses – ACUVUE 2 are available in various cosmetic tints like hazel, green, violet, amethyst, blue and even gray. There are also opaque acuvue contact lenses for darker eyes and enhancers for lighter eyes.

In the rush for a new change of “look”, people should consider that the contact lenses have its advantages and disadvantages. The advantages are that you benefit from a constant correction of your eyesight, you can wear lenses overnight (such as acuvue contact lenses), your binocular eyesight improves and your visual field gets larger. Unlike eyeglasses, they are excellent for bad weather and can even change the color of your eyes. Last but not least, you can get rid of those annoying spectacles which leave traumas to the children.

On the other hand there are disadvantages as well: contact lenses need more care than spectacles. Their purchase and maintaining cost is higher. Contact lenses are not recommended to children, old people or to those persons who suffer from severe allergies, eye infections, the syndrome of the dry eye or who work in an environment that doesn’t allow a proper handling of the contact lenses. However, if the person is mature enough to take care what he buys and wears, the contact lenses can be an answer to a prayer.

As you can see, contact lenses are made to fit everyone’s necessities and desires, from a simple change of “look” to a medical prescription. So, no matter what you’re looking for, be sure that there’s a suitable pair of contact lenses for you!

Thirty-five years ago, a company called Corning Medical Optics invented type of lens that changes color under direct UV exposure, they call it PhotoGray and PhotoBrown . As their names suggest, the lenses are available in either gray or brown colors that are light enough to wear indoors and darken to a sunglass shade when exposed to ultraviolet light.

The active ingredient that causes the lenses to transform is called silver halide and is mixed evenly throughout the lens. This means the whole lens will change when exposed to light. It also means that if a particularly strong prescription is made, the strongest, thickest part of the lens will be darker than the thinner parts. Also, if there is a large difference in prescription between the two eyes, the lens with the stronger prescription will be darker than the weaker one.

Since then, Corning has updated its offerings many times. What we carry is Corning's newest photochromics are SunSensors mid-index gray and brown plastic lenses. A bit lighter in weight and thinner than regular plastic, these lenses have photochromic molecules mixed throughout the material, rather than just in the top layer. However, unlike their glass counterparts, SunSensors change within 60 seconds to a uniform color density throughout the lenses, regardless of the prescription or lens thickness, according to the company.

Our full line of photochromic eyeglasses include single vision and progressive. We also carry photochromic lens by Transition, which is a big thinner than the Traditional Photochromic lens, but at high price.
