note: 6/6 vision is not ‘almost’ normal…it is normal.
Also, kindly recheck the part on PR.

Maam, could u also please take a class on anomalies on convergence and accomodation? Most of us find it difficult to understand.

Mam... Fc at 3 m and 3/60 is same thing?

[@hopesfaith5666]

If it is asked the angle subtended by the letter of 6/36 at 6m distance. What will be the answer mam ?

[@InsightOphthalmology]

30 minutes

[@amlik2628]

One doubt ma'am. How to assess C F. is it at distance of 3 ft/2ft/1 ft or in metre?

[@InsightOphthalmology]

It's in meters, based on the metric system if you use snellens in 6/6 notations
If you use the 20/20 feet notations of snellens then it's in feet

Why counting fingers only starts at 3m and not 6m?

[@AbhishekSingh-yx3os]

It's not necessary to start from 3 m u can start from 5 m too

[@parthvikotak3632]

Anyone help me to understand here what is 5 min ?

[@sheethalsunil7254]

It is they only take letters which fit in box eg: b this box is divided into 1 and they have collm 5 so they take it as 5 arc so 5min
