This video covers the basic rules for transposition and is designed along with the other videos in this channel to help the students in our training centre in Kinshasa. A knowledge of transposition is essential to understand how prescriptions are recorded, how to do neutralisation and how to do glazing.

I was struggling to understand the explanation by my optician, why there are two different ways of the same prescription. Now it's much clearer as my new glasses! Thankyou :)

Hi thanks for this. Is there anyway, for bifocals where there is reading lens, which numbers to add that to in order to get the reading glasses prescription? For example, with a distance prescription of -0.50, +2.75, 017 (vs it's transposition +2.25, -2.75, 107) , which transposition do I add this 1.75 number to in order to get the reading lens spherical prescription or does it matter?

Right: Spf -4.25 Cyl -1.00 Axis -170 Left: Spf -4.25 Cyl -1.75 Axis -170 Thats my glasses presrciption. Trying to buy contact lenses,there is an issue. Due to standar cyl numbers in forms... doctors and opticians can not agree what should i buy. Others say to subtract 0.25 cyl and other that i will feel dizzy with that. Could you help me transpose glasses prescription to contact lenses? Thank you!

Of course, if you wish, you can convert this prescriptions, by converting to Spherical Equivalent. To do that, you just take the "Spherical" measurement, and add 1/2 the astigmatic value. You can ignore the angle. I personally prefer being prescribed with a spherical lens - as I do that myself. Thanks for your excellent discussion.

@otissumnerbrown 9 жыл бұрын

Ian Squire Hi Ian - Thanks for your reply. I generally check my own refractive status using spherical lenses. If I can read the 20/20 line though a spherical, I just do not use a Toric. In my opinion, a person should be informed, that a toric lens is optional, if he has 20/20 though a spherical. I personally would not wear a lens, if I had naked-eye 20/20, with perhaps a self-measured astigmatism of 1.5 diopters. It means the difference between wearing glasses all the time, or wearing no glasses at all. (I would definitely given the patient that educated choice.

I appreciate your explanation of the optical cross, it was excellent! I am still a little confused of the 'why' in the 3 transposition rules you showed. Why does the cyl symbol change, why do you add or minus 90 to the axis etc?

@jimhaggard7436 Жыл бұрын

They’re equivalent that way. The “why” is because ophthalmologists typically write their prescriptions in plus cylinder while optometrists usually write their prescriptions in minus cylinder.

@drdenniskessler Жыл бұрын

@@jimhaggard7436 Why do ophthalmologists typically write in plus cylinder? Will the effect for the person wearing the glasses be any different? Will the overall thickness of the lens be the same if written either way? I guess in other words, will the lens be exactly the same if written either way???

@jimhaggard7436 Жыл бұрын

@@drdenniskessler I’m not sure why, but the effect is the same. The two prescriptions are identical as is the thickness of the lens.
