Hi there..
What Causes Blindness?
The following eye diseases and conditions can cause blindness:
i) Glaucoma refers to four different eye conditions that can damage your optic nerve, which carries visual information from your eyes to your brain.
ii) Macular degeneration destroys the part of your eye that enables you to see details. It usually affects older adults.
iii) Cataracts cause cloudy vision. They’re more common in older people.
iv) A lazy eye can make it difficult to see details. It may lead to vision loss.
v) Optic neuritis is inflammation of the optic nerve that can cause temporary or permanent vision loss.
vi) Retinitis pigmentosa refers to damage of the retina. It leads to blindness only in rare cases.
vii) Tumors that affect your retina or optic nerve can also cause blindness.
Blindness is a potential complication if you have diabetes or have a stroke. Birth defects, eye injuries, and complications from eye surgery are other common causes of blindness.

The following conditions can impair vision or cause blindness in infants:
– infections, such as pinkeye
– blocked tear ducts
– cataracts
– strabismus, or crossed eyes
– amblyopia, or a lazy eye
– ptosis, or a droopy eyelid
– congenital glaucoma
– retinopathy of prematurity, which occurs in premature babies when the blood vessels that supply their retina aren’t fully developed
– visual inattention, or delayed development of the child’s visual system

I hope that answers your question?
Best wishes,
