Dear Kalaivanan,

The near vision acuity requirement is more stringent in CP-189 and it requires acuity to read the Jaeger # 1 instead of Jaegar # 2 which is required by SNT-TC-1A.

For your information, smaller points = more demanding:

Jaeger Snellen Point
J1+ 20/20 3
J1 20/25 4
J2 20/30 5
J3 20/40 6
J5 20/50 8
J7 20/70 10
J10 20/100 14

I hope you will find this information useful.

Sincerely,
Hamid Reza

Dear Kalaivanan,

Use Jaeger 1 test chart to meet requirement of both snt-tc and cp-189.
