Corneal injury occurs when the surface of the cornea is torn, scratched or scraped from an outside object like contact lens, flying glass, plants, twigs or others.

Any two problems that may be seen in corneal injury are:

• This is a scratch or injury to the surface of the cornea that can cause pain, redness, tearing, and sensitivity to light, potentially leading to infection if not treated properly.
• A superficial injury seldom leads to permanent vision loss.
