A contact lens is a thin, curved, and transparent film that is worn over the eye to correct vision or for cosmetic purposes. Contact lenses are held in place by the tear film, a thin layer of tears that coats the eye. When the contact lens moves out of place, it can cause the tear film to rupture, causing a condition called a corneal abrasion.
A corneal abrasion is a scratches on the surface of the eye. It is a very painful condition and can cause tearing, redness, and light sensitivity. A corneal abrasion can occur when a contact lens is dislodged from the eye, when the eye is rubbed, or when foreign objects come into contact with the eye.
If you suspect that you have a corneal abrasion, it is important to see an eye doctor immediately. Corneal abrasions can lead to serious infections if they are not treated promptly.
