Visual impairment impacts a lot of people. It is when someone has a decreased ability to see.
I have always wanted to learn about vision and eyecare. Please tell me more.
Some people in the world do not have access to glasses or contact lenses, which puts them in the category.
That is awful.  Everyone should have access to vision care.  The government should provide it.
I agree. The term blindness is used for when vision is nearly or completely lost.
My doctor says i have glaucoma.  Bright light is blinding to me.  Will i be blind in the future?
Vision loss from glaucoma is permanent. Your outcome depends on the progression of the disease.
