ABOUT THE BLIND AND VISUALLY IMPAIRED

Definition of blindness

A person who has a visual acuity of 0.05 or less with better vision, as well as a person with a visual field reduced to the central part less than 10 degrees, is considered blind, provided that the loss of visual ability is definite and that medical or surgical treatment can’t fix it.

A person with visual acuity between 0.05 and 0.3 with better vision is considered visually impaired, provided that the decrease in visual ability is definite and cannot be corrected by correction with glasses, medication or surgical treatment.

CATEGORY I – consists of blind faces without visual function, ie those blind faces that do not have the ability to perceive light (amaurosis).

CATEGORY II – consists of blind persons whose corrected visual acuity in the better eye ranges between 0.02 and the sense of light or whose field of vision, regardless of visual acuity, is reduced to less than 5 degrees around the point of central fixation.

CATEGORY III – consists of blind persons whose corrected acuity in the better eye ranges between 0.5 and 0.02 or whose field of vision, regardless of visual acuity, is reduced to 5 to 10 degrees around the point of central fixation.

CATEGORY IV – consists of visually impaired persons whose corrected visual acuity in the better eye is between 01 and 0.05.
