Can Blind People See Anything?
Blindness is a somewhat elastic term used to describe a wide range of visual limitations.
Legal blindness isِ defined asِ falling short ofِ a statutory standard ofِ visual acuity: 20/200 vision inِ most ofِ the United States, orِ 6/60 inِ Europe.
Cataract sufferers experience cloudy orِ fuzzy images andِ struggle toِ seeِ shapes, whereasِ someoneِ with macular degeneration mightِ retain normal peripheral vision butِ gradually lose central vision.
All ofِ these disorders permit someِ level ofِ sight orِ light perception.
