Glaucoma is a disease that affects the optic nerve. The disease causes the nerve cells at the front of the optic nerve to die, which leads to partial or total vision loss. The first two types of glaucoma occur with in an eye that has no structural deformities. They are called Open Angle and Normal Tension Glaucoma.

Open Angle glaucoma, also referred to as chronic glaucoma, normally develops after the age of 35 and is the most common form of glaucoma. It occurs when aqueous fluid builds up and causes the pressure inside your eye to increase. The fluid is not drained properly because of a clog in the trabecular meshwork, a sponge-like, porous tissue which drains fluid from the eye. This happens gradually, with no symptoms. It can lead to partial or total vision loss and can only be detected through routine eye examinations.

The second type of glaucoma affects a small percentage of people and is called Normal Tension glaucoma. It occurs with normal eye pressure and can be attributed to an unusually fragile optic nerve or reduced blood flow to the optic nerve. This trait may be inherited and can only be monitored through routine eye exams.

Computer Vision Syndrome, or CVS, is characterized by tired and sore eyes, headaches, neck and shoulder pain and general body fatigue. It is the number 1 complaint in the workplace and affects everyone who works on a computer.

CVS is brought on by the way the computer screen works. An image on the screen is made up of thousands of tiny colored squares called pixels. These pixels are constantly changing in color and brightness which causes your eyes to refocus. This constant refocusing is what causes the systems of computer vision syndrome.

The only sure fire method to prevent CVS is to wear specialty prescribed computer glasses. These can range from specialized multi-focal lenses to single focal lenses used specifically uses while using the computer.

However, you can also combat the effects of CVS simply by setting up your workspace. Place your computer screen approximately 20 to 40 inches away from your eyes, directly in front of you and position it so there is little to no glare on the screen. Make sure the screen height is setup properly so it can be viewed without looking down or slouching in your chair. Finally a desk lamp maybe used to provide more light without increasing glare.

While proper arrangement of your workspace will help reduce the effects of CVS, you should consult your eye care provider to fully prevent CVS.
