What is the difference between blindness and low vision?
Low vision refers to a severe visual impairment in which visual acuity is 20/70 or poorer in the better-seeing eye and cannot improve with glasses or contacts. Legally blind means a person has a corrected vision of 20/200 in their best-seeing eye.

If you suspect that you may have vision impairment, it’s always best to consult with an eye specialist.
