I am an Engineer. I am forced to make my own refractive state measurements myself. For that reason, I call them, scientific objective.

total power of the eye is 60D (43+17)

[@optometrywithkhurram6867]

Different authors mentioned different power of the eye .so it's not a big deal dear..you can mention 60D as well.👍

[@otiebrown9999]

When you do not do it yourself, using your own test lenses.

why lot of doctorrs talk about myopia in adults but not about adults who have hyperopia

[@manishpatil9114]

Hi

[@santhieswari8537]

Excellent explanation sir thanks

[@ammusuni21]

What sir one small topic your enlarging repeat explanation

[@washimahmad9289]

So well explained sir❤

[@mafia1270]

Sir, correct me if i'm wrong, based in my experience, the px would see the target become smaller but clearer when overminused and from your past lesson , when overminused, there s a tendency to make the px to become hyperopic. That's why we should do the " least minus and maximum plus in making the prescription...but may i ask, what about in cases of hyperopic, is there such as overplus when we hqve to choose the maximum plus and is it the same response frm the patient that they see the target becme smaller..when should we stop in adding plus lenses in hyperopic, how do we knw that is is the best plus sphere in hyperopic..thank you so much

[@optometrywithkhurram6867]

Correct one thing.. when you will make your patient over minused..objets or optotypes will get smaller, In contrast when you will make your patient overplused, it will take that patient towards sort of myopia, but it will cause magnification always, and the reason is the specific type and manufacturing of plus lens, which always cause magnification. To choose best plus or best minus end point you have to perform duo chrome test.

[@mafia1270]

@@optometrywithkhurram6867 ah ok thank you so much sir doc, yes i do perform the duchrome..so now i am sure that i'm on the right path..thanks for confirming..thank you so much for all the lectures,.. when i missed something and got confused, i always get back to your lectures..you're a great help..,all thanks to you sir doc!!

Sir doctor prescribed my sight as 2.50 in right and 2.70 in left but while subjective refration doctor asked me which lense is better but i couldn't say correctly which i could see clearly in my right eye .i think not such big difference between the two but if i say wrong could it cause any problem or my eye can adjust to it?

[@besoftcool]

Nice video sir..how to use a plane mirror retinoscope., how much time to get refraction & refractive numbers, plane mirror retinoscope needs dark room or dim room, it should accurate? any chance make a video for plane mirror retinoscope

[@ganeshsolanki5596]

Sir how to we know that pt is accomodate or un accomodate during refraction pls tell me any tricks....
