Risks of getting sand in your eyes
Sand in your eye is usually not a case of emergency and would likely resolve on its own. However, it could also lead to complications in severe cases.
Corneal abrasion
Corneal abrasion [3] occurs when sand or particles end up scratching your cornea, the outer layer of your eye. It doesn’t usually cause permanent eye damage and may heal on its own within 1 to 3 days. However, it can cause severe pain, vision obstruction, and may require medical attention.
Infections and other complications
If the object scratches your cornea deeply it could lead to an infection. Although this is rare, it is usually due to rubbing or touching your eyes after having washed your hands. While it is better to not touch your eyes at all, if you must, it is best to wash your hands first.
