in the U S , 1) visual acuity of 20/200 or worse in the better eye with corrective lenses (20/200 means that a person must be at 20 feet from an eye chart to see what a person with normal vision can see at 200 feet), or 2) visual field restricted to 20 degrees diameter or less (tunnel vision) in the better eye NOTE: These criteria are used to determine eligibility for government disability benefits and do not necessarily indicate a person's ability to function

A person is considered "legally blind", in the USA, when their visual acuity is 20/200 or less in the better eye with best correction, or their field of vision is 20 degrees or less in the better eye Coloboma of the macular and or optic nerve can cause legal blindness
blindness as recognized by law which in most states of the U S means that the better eye using the best possible methods of correction has a visual acuity of 20/200 or worse or that the visual field is restricted to 20 degrees or less
= a central vision acuity for distance of 20/200 or poorer in the better eye with correction; or a field of vision no greater than 20 degrees in widest diameter
In the U S , (1) Visual acuity of 20/200 or less in the better eye with corrective lenses (2) Visual field restricted to 20 degrees diameter or less (tunnel vision) in the better seeing eye Note these criteria are used to determine eligibility for government disability benefits and do not necessarily indicate a person's ability to function
The term legal blindness is used by the Internal Revenue Service and others to determine whether you are eligible for disability benefits or services There are two definitions of legal blindness, depending upon whether you have lost central or peripheral vision You are legally blind if central vision in your better eye with the best correction possible is no better than 20/200, or if peripheral vision in your better eye is no greater than 20 degrees diameter (10 degrees radius) You are not legally blind if you are blind in only one eye
refers to clinically measured visual acuity of 20/200 in the better eye with best correction, or visual field of 20 degrees or less
