Everyone in my family has bad vision. I've been wearing glasses since I was five.
I see, well visual impairment occurs when there are significant issues with vision that can't be fixed with glasses.
Is there any other way it can be fixed?
It depends on the cause, for instance cataracts are the most common cause of blindness.
My mom had cataracts when she was in her 20s. She had to get surgery to fix it.
Wow, I'm glad she was able to fix it. There are other causes of visual impairment such as macular degeneration and diabetic retinopathy.
Are most people born with visual impairments?
Visual impairment
Visual impairment, also known as vision impairment or vision loss, is a decreased ability to see to a degree that causes problems not fixable by usual means, such as glasses. Some also include those who have a decreased ability to see because they do not have access to glasses or contact lenses. Visual impairment is often defined as a best corrected visual acuity of worse than either 20/40 or 20/60. The term blindness is used for complete or nearly complete vision loss. Visual impairment may cause people difficulties with normal
considerable overlap occurs. People with nuclear sclerotic or brunescent cataracts often notice a reduction of vision. Nuclear cataracts typically cause greater impairment of distance vision than of near vision. Those with posterior subcapsular cataracts usually complain of glare as their major symptom.
The severity of cataract formation, assuming no other eye disease is present, is judged primarily by a visual acuity test. Other symptoms include frequent changes of glasses and colored halos due to hydration of lens.
