👉 Blepharism is a condition in which one's eyes are too sensitive to light. It can cause pain, discomfort, and difficulty seeing in certain parts of the eye. Blepharitis can be caused by various factors such as dryness, irritation, or inflammation of the eyelids. If left untreated, blepharitis may lead to other eye problems such as cataracts, glaucoma, or even blindness.
