When used -0.5 cylinder lens spherical is reduced from -0.75 to -0.5. Then after correcting cylinder -0.5 spherical is again changed backed to -0.75. This means no need to reduce spherical power when adding cylinder?
platform no we always need to reduce spherical power whenever the cyl power is increased by 0.5.. I dont know if explain it well so for every additional -0.50 cyl, we need to reduce the sph by 0.25.. because we need to make sure that the cercle of least confusion is on the retina
Patient is having refractive error, we've given optimal glass correction, prescribed glasses. Patient came after 1 week , complaining that , after wearing glasses, he's uncomfortable and developing astenopic symptoms.BCVA 6/6. What is the expected reason??? Waiting for your reply Sir. Thank you.
Excellent! Shows how difficut cross cyl is. Thanks
in searching for astigmatism, why did you use -0.25 and not -0.50 also why minus and not plus? need help please!
Good but trial frames was not set up correct, the lens was not centered
Correct.
you are the best 😍
Duchrome test not in dark room?
Objective refraction not performing prior to subjective
Sir I ned your help

this was very usefull for a design research im doing! thanks!!
What's that music for. The video is very good

Thank you.
Wait - forever.
She is laughing why?
I found this very helpful, thank you so much! #photosynthesis
fantastic
Can i get hindi option ?
Nice video but one video retinoscope
Nice 👍
786 optical center
Good job
Just traslent in Tamil
I want hindi
I want telugu
hahaha,, zayn
Hindi me bhejiye
Nice .but it should in hindi tooo
