The term “blind” is used to describe the loss of sight. There are many causes of blindness, including disease, injury, and congenital conditions. Blindness can be temporary or permanent.
Causes of blindness include:
Disease: Blindness can be caused by diseases such as glaucoma, cataracts, macular degeneration, and diabetic retinopathy.
Injury: Blindness can also be caused by injuries to the eye or head, such as a blow to the head or a penetrating injury to the eye.
Congenital conditions: Some people are born with conditions that cause blindness, such as albinism and optic nerve hypoplasia.
