Tears are an extremely vital part to clear vision and your overall eye health. Dry eye is a condition where your eyes don’t produce enough tears, or the tears that your eyes do produce don’t have the proper chemical composition. Dry eye can often occur as part of the natural aging process, but can also be caused by blinking or eyelid problems, antihistamines, oral contraceptives, antidepressants, dry climate, wind or dust, general health problems like arthritis or Sjogren’s syndrome, or chemical or thermal burns to your eyes.
Dry eye symptoms include:
- Irritated, scratchy, dry, uncomfortable, or red eyes
- Burning sensation
- Feeling like something foreign is in your eyes
- Blurred vision
Excessive dry eyes can damage the eye tissue, scar your cornea, or impair your vision and make it difficult to wear contact lenses.
