Contact lenses are classified as "highly controlled medical devices," just like cardiac pacemakers. Colored contact lenses are also classified as such. The curvature of the eye varies from person to person. There are various types of lenses to suit a person's lifestyle, tear production, degree of nearsightedness or farsightedness, etc. Continuing to use contact lenses that do not fit your eyes properly can "damage the cornea and cause eye problems." It is important to have lenses that fit your eyes properly prescribed by an ophthalmologist.

The cause is contact lenses that don't fit your eyes.

Corneal epithelial damage

Please be careful not to sleep with your contact lenses in, even if you're just dozing off.
