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.
