Keratitis: is a condition in which the eye’s cornea,
the front part of the eye, becomes inflamed. Caused either
by infectious or a noninfectious process. The condition is
often marked by moderate to intense pain and usually
involves impaired eyesight.

Superficial keratitis involves the superficial
layers of the cornea. After healing , this
form of keratitis does not generally leave a
scar. However deep keratitis involves
deeper layers of the cornea, and leaves a
scar when healing that impairs vision. If
treated immediately, this can be reduced
or avoided.

to prevent light from causing further irritation
