Trichiasis The inward turning of an eyelash. If it scratches the cornea, there is discomfort similar to a foreign body sensation.
RELATED TERMS--------------------------------------
Eyelash
One of the familiar stiff hairs that project from the margin of the eyelid. Eyelashes tend to be noticed mainly when something goes wrong with them. An eyelash gets in your eye and irritates it; you have an ingrown eyelash; your eyelashes fall out, etc.
Cornea
The front part of the eye that acts as a window for the entrance of light rays. It is attached to the other outer coat of the eye, the sclera; the white part of the eye.

Because it has many nerve fibers, an injury or foreign body causes significant pain and discomfort.
