Snow blindness is a burn of the cornea (the clear front surface of the eye) by light reflected off snow and ice. The condition typically occurs at high altitudes on highly reflective snow fields or, less often, with a solar eclipse. Symptoms include tearing, pain, redness, swollen eyelids, headache, hazy vision, and even a temporary loss in vision.
