Junior Blind serves infants, children, youth and adults who are blind or visually impaired.
The estimated incidence of blindness ranges from 1-2% of the population of birth to 20 years, 4.5% for those ages 65-75, 10% for those ages 75-84, and 26% for seniors over age 85.
People who are legally blind have a best corrected central visual acuity in their better eye that does not exceed 20/200 and/or a visual field whose maximum angular diameter does not exceed 20 degrees.
People are functionally blind if they are totally blind or if the best corrected visual acuity in their better eye is not better than light perception.
People are visually impaired if they are not legally blind, but their best corrected central visual acuity does not exceed 20/70 or if the maximum angular diameter of their visual field does not exceed 30 degrees even if their best corrected visual acuity in their better eye exceeds 20/70. People are totally blind if they are unable to visually detect light of any intensity. People are said to have light projection if, with their better eye, they can detect light and determine from which direction the light is coming.
