Blindness

Blindness is the condition of poor visual perception. Various scales have been developed to describe the extent of vision loss and define blindness. Total blindness is the complete lack of form and visual light perception and is clinically recorded as NLP, an abbreviation for “no light perception.” Blindness is frequently used to describe severe visual impairment with some remaining vision.

Those described as having only light perception have no more sight than the ability to tell light from dark and the general direction of a light source. The World Health Organisation defines low vision as visual acuity of less than 20/60 (6/18), but equal to or better than 20/200 (6/60), or visual field loss to less than 20 degrees, in the better eye with best possible correction. Blindness is defined as visual acuity of less than 20/400 (6/120), or a visual field loss to less than 10 degrees, in the better eye with best possible correction. Children with a poor visual perception have to improve their other senses and their body-awareness, particularly when the child was born preterm.
