I am planning on purchasing my first differentials ever, but came across a few questions I’d like to ask.
My current prescription is:
OS: sph -5.50
OD: sph -5.50, cyl -1.25 axis 060
After reading several blog posts about the topic, and about the importance of not making several focal changes at the same time, I was thinking of just reducing the spherical and keeping my cylinder exactly the same - and see how my eyes respond to that. My idea was to tackle the cylinder last of all on my journey, and just concentrating on reducing the spherical for now.
But revising Jake’s email series, he says to drop the cyl if it is -0.25, or to just reduce -1.25 sph (instead of the standard -1.5) if there is a 0.50 cyl, for the first differentials. Then on the forums or Facebook I have read that if cyl is 1 diopter or less, to just drop it and compensate it with spherical instead.
So now I’m feeling confused as to what to do, because my cyl is -1.25 (over 1). So I wondered if I should drop some little cylinder too for my first differentials and compensate with spherical? or just drop the spherical, and keep the cylinder intact for now anyway.
So I guess my question is - Is it okay to keep the high cylinder exactly the same and just drop the spherical for your first differentials? Or is keeping a high cylinder for close-up differentials a bad idea or a no-no?
I’m not asking for diopter-specific advice - I’d just like to make up my mind about how to handle any high astigmatism before I buy any glasses, and the posts I have seen up to date have left me a little confused.
I apologise in advance if this has been addressed before (if so, please feel free to share links!)
