It is a transparent bulged out structure covering the pupil. It is because of the cornea that our eyes attain 2/3rd of its refractive power. Diseases, infections and excessive strain onto the cornea lead to its thinning or successive translucency. As a result, it causes loss of vision. Even so, the WHO (World Health Organization) has declared corneal blindness to be the 4th top-most reason of blindness around the world. Some common problems which lead to corneal blindness are:
