Blindness & The Partially Sighted
Ever curious to wonder what defines or classifies blindness over partial sight? Always wondered what tools the blind and partially sighted use? Sometimes those with sight confuse blindness and the partially sighted when they see a person walking around with a cane. As all know, a cane is a symbol of blindness but few ever understand that the cane is used for both the blind and partially sighted. Below are a few items to compare each section (sighted (except for tools), blindness, partial sight and low vision. If you feel you have symptoms of an eye condition that can be corrected it's best to seek a doctor for guidance.

- A term that indicates some type of visual problem has resulted in a need for special education.
- Individuals who have reduced vision even when using the best possible spectacle or contact lens correction available. It can be a result of either congenital disease (e.g. Retinitis Pigmentosa or Leber's Congenital Amaurosis) or acquired factors (such as in some forms of optic atrophy).

- 20/500 to 20/1,000 is considered profound visual impairment, or profound low vision
- More Than 20/1,000 is considered near-total visual impairment, or near total blindness
