Dry Eye symptoms include scratchy eyes, burning, mild redness and gritty feeling eyes. Dry eye is caused by a problem with the lubricating tears.
In some cases, not enough tears are made to moisten the eye. In others, enough tears are made, but they don't have the right amounts of each layer to work right. The tears may be too watery or too sticky to properly lubricate the eye. When the cornea is irritated, the body tries to fix this by making more tears, so dry eye can actually cause your eye to water. Since these tears aren't able to properly lubricate the eye, making more of them doesn't solve the problem.
Oral medications, reading, computer tasks, and dry environments may aggravate marginally dry eyes. Dry eye can be diagnosed by using dyes to observe tear patterns, evaluation of the amount of tears on the front of the eye, and from a review of your symptoms. Treatment may include artificial tears, eye drops for treating allergies, and/or punctal plugs inserted in the tear drainage canals, etc.
