Tears are a complex mixture of water, fatty oils, proteins, electrolytes, bacteria-fighting substances and growth factors that regulate various cell processes. This mixture helps make the surface of your eyes smooth and clear. Without tears, good vision is impossible.
For some people, the cause of dry eyes is an imbalance in the composition of their tears. Other people don’t produce enough tears to keep their eyes comfortably lubricated. Eyelid problems, medications and other causes, such as environmental factors, also can lead to dry eyes.
This condition makes the eyes feel dry, scratchy, and gritty. Other symptoms may include: burning, stinging, itching, pain, sensitivity to light, redness, blurry vision, a feeling that there is a speck of dirt in the eyes, and/or a stringy discharge from the eyes.
Though dry eyes cannot be cured, there are a number of steps that can be taken to treat them. You should discuss treatment options with Dr. Fox if this is a problem for you.
