Explanation
Answer: A - Low vision is NOT the same as legal blindness. Legal blindness is defined as a visual acuity of less than 20/200 or visual fields less than 20 degrees in the better seeing eye with best visual correction.

Low vision is better defined in terms of functional uncorrected visual loss rather than numerical visual acuity. It is the reduced vision that makes day-to-day activities difficult. People with low vision do not show improvement in vision with spectacles/medicines/surgery.
