Watch the video below about Sean Belahovick, who was almost completely blind due to a condition called keratoconus. The condition causes the cornea to bulge outward into a cone shape, which deteriorates vision and can cause blindness. Luckily, Sean’s eyes were corrected by a cornea-strengthening procedure. And although the condition is rare, comprehensive annual eye exams can identify this condition as well as others that can cause problems from an early age.
