Dry eye disease is a common condition that occurs when your eyes don’t produce enough tears or when the tears you produce are of poor quality. Tears are essential for lubricating the surface of your eye, washing away debris, and protecting against infection. When your eyes are dry, they can become irritated, uncomfortable, and even blurry.

The symptoms of dry eye can vary from person to person, but common symptoms include:

• A gritty, scratchy, or burning sensation in your eyes.

• Redness of the eyes.

• Blurred vision, which may fluctuate.

• Sensitivity to light.

• Excessive tearing, followed by dryness.

• A feeling that something is in your eyes.

• Difficulty wearing contact lenses.

Dry eye can be caused by a variety of factors, including:

• Age: Tear production naturally decreases with age.

• Hormonal Changes: Hormonal changes associated with menopause, pregnancy, and thyroid disorders can affect tear production.

• Medical Conditions: Certain medical conditions, such as Sjogren’s syndrome, rheumatoid arthritis, and lupus, can cause dry eye.

• Medications: Certain medications, such as antihistamines, decongestants, and antidepressants, can reduce tear production.

• Environmental Factors: Exposure to wind, smoke, and dry air can exacerbate dry eye symptoms.

• Eyelid Problems: Conditions that affect the eyelids, such as blepharitis, can disrupt tear production.

• Contact Lens Wear: Long-term contact lens wear can reduce tear production.
