“Corneal abrasion,” which is scratching of the clear outer layer at the front of the eye, is one of the most common kinds of eye injuries. Corneal abrasions are quick to heal, but they are painful. The traditional treatment for this injury involves wearing an eye patch. However, there is research that suggests that the initial use of an eye patch actually slows healing and does not reduce pain. Moreover, researchers conclude that since corneal abrasions do not affect vision to a great extent, it is rather pointless to render patients with scratched corneas “monocular” (one-eyed). Foregoing the use of an eye patch may actually help corneal abrasions heal more quickly on the first day after the injury.
P.S. The cornea is vulnerable to burning from excessive exposure to the sun’s ultraviolet rays.
