Dry Eyes: Symptoms include scratchy eyes, burning, mild redness and gritty feeling eyes. Oral medications, reading, computer tasks and dry environments may aggravate marginally dry eyes. Dry eyes can be diagnosed by using dyes to observe tear patterns, evaluation of the amount of tears on the front of the eye and from review of your symptoms. Treatment may include artificial tears; eye drops for treating allergies; and/or punctal plugs inserted in the tear drainage canals.
