NETRA-G: Towards a Subjective Self-Refraction

Not Accessible

Your library or personal account may give you access


We discuss NETRA-G’s sphero-cylindrical self-refractions for teenagers. NETRA-G achieved accuracies of .48D on sphere and .30D on cylinder. Visual acuity was 20/20 or better in 70% of all cases and 20/25 or better for 90%.
