This video was way too helpful..Due to this lock down I am not able to practice all the instrument uses...But your vidoe helped me a lot to brush up my memory👍👌
Mam apne jo near aur distance power nikale the fir apne unko add kiya to +1,25 aa raha h .jabki uske +2,00 ka sphere laga h to kon sa usko prescribe krenge
How do I know what axis to choose. I can't understand honestly If B is bigger than A I chose B axis? So the cyl is in + But if B is smaller than A , do I choose A axis? Working in minus cyl?
Here the axis for -2 cylinder should be at 170° because the smaller number axis we take for prescription and I am very sure and confident about it ! The smallest number is sphere and works in all meridia but for cylindrical axis we take the difference on the axis between the two numbers with bigger number sign (+/-) and smaller number that we choose for sphere that axis becomes the axis for the cylinder here she has made a mistake it's -2 cylinder should at 170° and not 80° and I am very sure and confident about it !
Final reading should be -2.50/-2.00 @ 170° and not 80° And the the central sphere thing I mean how to calculate the axis I didn't get you said central dotted sphere should be clearly in line with the cleared line in one meridian that thing I didn't get because I didn't see the central dotted circle and how it came in line with the previously clear line we got in one meridian ! But I must say this is the best video no one has explained this well in a short time this much short time and very very well explained I would have liked to see cylinder only lens also Prisms I would like to see how to calculate prism power on this lens meter also how to neutralised lenses manually and how to identify prism lens I must watch other videos for that for manual neutralisation of lenses later on ! But very nicely explained your voice is very cute and sweet absolutely non irritating though you don't have a proper foreign accent but the your tone and voice quality is so calming absolutely non irritating in fact you sound very cute and sweet ! Thank you !
After watching other videos I am correct for refraction prescription but for lensometer here I see there is other formula to calculate the axis that the minimum minus number axis is selected and axis for maximum positive number is selected so you are right ! Very nice video soothing calming I just wanted prism manual detection and manual neutralisation !

How to use in spherocylindrical
What type of lensmeter is this?
Great Effort, Kudos.... :)
Mam here we are measuring back vertex power for both distance and near is that alright mam! ?
thanks for your video. what is the formula for spheris cylinder bifocal.
Crystal clear😊.... thank you so much❤

Wonderful and clear explanation
Dear I have Manual lens meter, but due to dust I can't see the reading number, would you please show me how to clean the dust?
How to find add power in sphrocylinder lens
Very good presentation
Make a video.
Plus cylindrical and change it into sphero cylindrical form
This video was helpful but i did not get how to put axis on cylindrical power lens, please make more videos on it ,🙏
Nice information
How to chaikh progressive number
Very helpful video 🙂
Mam your sounds is so good
sister i have one dought
A-2.00×180
B-2.00×90
?
This is not a cylinder lens but a Sphere lens idiot
Your question is not correct, is it in the + or - ? And are you asking about bifocal lens?
Thank you ❤
amazing
Thankyou 😊
Hlo mam kya me aap se baat kar skata hu please
Deserves a HEART🫴🏻❤️
goood moolooos
Thanks
vedio please hindi me bnaye
Hindi please.. Please please
Madam Hindi ma pls batya.
