Does rubbing your eyes damage them?
Studies have shown that continuous eye rubbing can result in thinning of the cornea, which becomes weakened and pushes forward, becoming more conical. This serious condition is called keratoconus, and can lead to distorted vision and possibly the need for a corneal graft.
