-
Blindness: Condition where a person has any of the following in the better eye with best correction:
- Total absence of sight.
- Visual Acuity (VA) ≤ 3/60 (Snellen) or ≤ 10/200 (US equivalent).
- Limitation of Field of Vision (FOV) subtending an angle of ≤ 10 degrees.
-
Low Vision:
⭐ "Under the RPwD Act 2016, 'low vision' means a condition where a person has visual acuity between <6/18 to 3/60 (Snellen) in the better eye with best correction, or a visual field limitation of <40 degrees to 10 degrees."

- Both VA and FOV are considered for certification.
