It often involves having a best-corrected visual acuity of 20/200 or worse in the better eye or a visual field restricted to 20 degrees or less.
Low Vision: Some individuals have low vision, which means they have some remaining sight but experience difficulty with everyday tasks. They may use magnifiers, large-print materials, and adaptive technologies to enhance their remaining vision.
Blindness: Total blindness refers to the complete absence of vision, whereas individuals with partial sight may still perceive light, shapes, or movement.
