Overview Of Dry Eyes
- Dry eyes take place when your eyes do not create enough tears.
- Tears are required to help keep sufficient moisture in your eyes. They help to keep the eye surface even and also help to guard the eyes from impurities.
- Dry eyes might sting or itch and can be very painful. You might experience dry eyes constantly or only during particular situations.
- For example, you might have dry eyes after looking at a PC for a long time, or when it is breezy outside. Both eyes are generally affected at the same time.
- Eye dryness will possibly affect everybody at one point. It is seldom serious and can generally be treated with medication.

- Other medical disorders such as lupus, diabetes, infections, allergies, rheumatoid arthritis, or a thyroid disorder.
- Injury to the tear glands, swelling, biochemical burns, heat, or radiation.

- Decongestants;
- Allergy drugs, such as antihistamines;
- Antidepressants;
- Birth control pills;
