∆ y axis : 1.5 D
∆ x axis : -2.5 D
Right Eye : 1.5 (y axis), - 0.5 x axis

Great explanation dear....thanks a lot

[@ronak_singh_]

-0.5sp,-1.5cy/180axis
So it will be -1.25sp
Am i right?

[@optometry-with-samir]

Yeah. You are right

[@ronak_singh_]

But can -1cy lens can replace -0.5sp lens?

[@optometry-with-samir]

@@ronak_singh_
Yeah but patient satisfaction is more with Spherical power than cylinder power.

[@me56743]

What about when axes are not 180°

[@optometry-with-samir]

Axis doesn't matters...

[@janardhanchiluka]

-2.00-1.00 90 it will be the same

[@optometry-with-samir]

It will be: -3, +1.00 X 180

[@velmuruganagalya5774]

[@optometry-with-samir]

Optometry is a English based course. You have to learn it in English. If you skip English now you will suffer in future.

Brother please improve your English if you are targeting foreign audience
