Blind, vision (or visual) impairment and low vision are frequently used terms. These terms identify a person who experiences difficulties seeing, even when corrected with spectacles.
- corrected visual acuity on the Snellen Scale must be less than 6/60 in both eyes, or
- constriction to within 10 degrees or less of arc of central fixation in the better eye, irrespective of corrected visual acuity, or
- a combination of visual defects resulting in the same degree of visual impairment as that occurring in the above points.”
Vision impairment is a term used as an overall description of people who experience sight loss. A Booklet “Better Information & Communication Practices” which could be downloaded from the FaHCSIA website defines vision impairment to include “people who are blind and people who have limited vision”.
