Questions & Answers

How are blind, deaf, and disabled defined?

Blind means a person whose central visual acuity does not exceed 20/200 in the better eye with correcting lenses, or whose visual acuity is greater than 20/200 but is accompanied by a limitation in the field of vision such that the widest diameter of the visual field subtends an angle no greater than 20 degrees.

Deaf means a person whose average loss in the speech frequencies (500-2000 Hertz) in the better ear is 82 decibels, A.S.A., or worse.

Totally disabled means a person who is totally and permanently disabled, either physically or mentally, which results in the person's inability to engage in any substantial gainful business or occupation. It is presumed that a person whose earned income, before deductions and exemptions, exceeds $30,000 per year is engaged in a substantial, gainful business or occupation.
