WHAT IS VISUAL IMPAIRMENTS

The term ‘visual impairment’ refers to people with irretrievable sight loss and this simple definition covers a wide spectrum of different impairments.

It does not include those whose sight problems can be corrected by spectacles or contact lenses, though it does include those whose sight might be improved by medical intervention. If you are short sighted or long sighted, but you can see normally when you put your glasses on or wear your contact lenses, you are not visually impaired.

Visual impairments is the condition of lacking visual perception due to physiological or neurological factors.

Totally visually impaired is the complete lack of form and visual light perception and is clinically recorded as NLP, an abbreviation for no light perception.
