Computer vision syndrome (CSV) and dry eye is a common problem in this period of time when computers are being used by a great many people on a daily basis for extended periods of time, we can experience a variety of problems related to computer vision syndrome, although there is no hard evidence that computers can damage eyes, they can contribute to symptoms such as dry eye, eye strain, focusing difficulties, red eyes, neck pain and blurred vision. Although these symptoms are not caused by the screen itself they are more related to the ways in how we sit and focus on the screen and ergonomics.
Functions of the eyes
Our eyes are designed to blink on the average of 18 times a minute, this action wipes away debris from the surface and maintains healthy functioning of the eye. Many of us whilst sitting at our computers may only blink up to six times a minute, this can irritate the eye and cause a condition called dry eye. Our eyes are designed to focus 20 feet or 6 metres ahead of us. Looking at a computer screen less than a metre from of us uses a different set of internal eye muscles which can result in eye strain.
A great majority of people with dry eye problems are often diagnosed with Meibomian gland dysfunction (MGD) or Blepharitis. The meibomian glands are located near our eye lashes and provide some of the lipid secretions that make up part of our tear film.
Some of the causes of (CSV) and (MGD)
- Sitting your shoulders hunched and head thrown forward for long periods of time, although this is not a reason for (CSV) or (MGD), proper blood flow to the brain can be reduced
- Staring at the computer without blinking for extended periods
- Sitting too close to the screen
- Chair and computer desk inappropriately positioned
The American Academy of Ophthalmology has recommended some steps to help reduce Computer vision syndrome
- Every 20 minutes focus on an object or view which is at least 20 feet (6 metres) away from you
- Take regular breaks from your computer, get up and walk around for a couple of minutes
- Sit at a comfortable position from the computer and positi8on the screen so that your eyes look slightly downwards
- Place a reminder on your computer screen to remind yourself to blink often
To Relieve symptoms of (CSV) or dry eye problems
- Artificial tear drops which lubricate the eyes, relieving some of the discomfort
- Use a warm compress to massage the eyelids for about two minutes twice a day, heat from the compress allows the sticky oily secretions from the glands to melt slightly, and can relieve the blockage, after the warm compress use a wet cotton bud to scrub the eyelashes to remove any oil secretions that the glands have released, try to do this twice a day for at least a month to see improvements
- Add an Omega-3 supplement to your diet, this has proven helpful to those with dry eye symptoms, make sure you use a good quality omega-3
- Many diets today include an excess of Omega 6, this limits the effectiveness of omega-3 in helping dry eye and (MGD). The ideal ratio of omega-3 to omega-6 is 1:4. At least 500mg of Omega-3 is recommended by the American Dietetic Association.
Foods that contain Omega-3
- Indian mackerel
- Spanish mackerel
- Canned tuna
Foods that contain Omega 6
- Vegetable oils such as sunflower, Corn oil, Rapeseed oil, Sunflower oil
- Cereals and whole grain breads

Dr. Maskin begins with an overview of dry eye syndrome, then explains the myriad ways it can develop (allergies, aging, contact-lens use, LASIK surgery, diabetes, and various other diseases). He discusses how it can be successfully diagnosed and treated, offers guidelines for choosing a doctor and appropriate medications, and describes useful home remedies.

|Refresh Plus Eye Drops does more than just soothe and relieve dry and irritated eyes. It also provides long-lasting moisturizing protection in a formula that contains many of the same healthy qualities as natural tears. Refresh Plus is preservative-free for sensitive eyes, and can be used as often as needed to provide 24-hour comfort. If your eyes are severely dry then you should use drops that are preservative free because they can sting and become more irritated from preservatives, that is what always happened with me. If your eyes are irritated that can cause tears and your tears can dry out your eyes even more(I know that sounds wrong but it is true)Also, if you read most eye drops or ask your eye Dr, you are only supposed to use certain eye drops a certain number of times per day. Most of the eye drops I had been using I could use and less than 30 minutes later my eyes would be dry/irritated again. The Refresh Plus my eye Dr said that I could use them as many times a day as I wanted to and that right after Lasik they would help my eyes heal.|
