Legally blind is not completely blind.
If you’re completely blind, you can’t see any light or form. Of the people with eye disorders, only about 15% can see nothing at all. If you’re legally blind, you can still see -- just not that clearly.Normal vision is 20/20. That means you can clearly see an object 20 feet away. If you’re legally blind, your vision is 20/200 or less in one eye. That means if an object is 200 feet away, you have to stand 20 feet from it in order to see it clearly. But a person with normal vision can stand 200 feet away and see that object perfectly.
An estimated 1.1 million Americans are legally blind. Some conditions, like glaucoma, cataracts, diabetes, and macular degeneration can affect your sight to the point that you may be diagnosed with the condition.
