What is low vision?

imageLow Vision is a term used to identify individuals whose vision cannot be corrected to 20/20 with conventional spectacles or contact lenses. Individuals who are categorized as visually impaired have best corrected visual acuity of 20/70 to 20/100. Individuals who are categorized as legally blind have best corrected vision of 20/200 or worse. For example if a person has best corrected vision of 20/100 that person can see a letter on an examination chart that is 20/100 in size at only 20 feet where a person with 20/20 vision can see a 20/100 letter at 100 feet.
