3. The sensation of a foreign body in the eye is one of the symptoms you’ll experience with an eye ulcer.
It will cause you to place your fingers in your eye to see if there is something stuck in there. It is not a good idea to place dirty hands in your eyes. If you must touch your eye, wash your hands thoroughly with soap and warm water. Contact lens wearers have this symptom, especially if they wear dirty contacts. It will feel as though there is a foreign body in the eye, even when the lens is taken out.
There is nothing in the eye, it’s from the eye ulcer. The eye is infected and needs to be treated at the eye doctor. Once the eye ulcer heals, the eye doctor may suggest to stop wearing contacts and use prescription eyeglasses since you don’t know how to properly use them.
