There are many ways to lose your eyesight. Most blindness is caused by diseases and malnutrition. Glaucoma, cataracts, uveitis, macular degeneration, trachoma, corneal opacity, and diabetic retinopathy are the most common diseases that cause blindness. Other causes of blindness are injuries, genetic defects, poisioning and self-harm. You can also go blind by staring directly at the sun.
