Happy new year!
I recently joined back to 20/20, but need some advice as I have high myopia & asthigmatism. A bit stuck and not sure how to proceed (I am at the ‘Strain Minimizer: Differential Diopters’ module). Module suggests starting a new thread in the forum if needed, so posting with my details.
Some facts about my eyes:
My last eye test was Feb 2020 and my presecription was: R (sph:-9.25, Cyl:-1.25, Axis:165) & L (sph:-9.25, Cyl:-1.50, Axis:15).
However, I didn’t get new glasses then and have been wearing my old prescription from Nov 2017, which is: R (sph:-8.75, Cyl:-1.75, Axis: 172) & L (sph:-8.50, Cyl:-1.50, Axis:12). With these glasses I can see 20/20 on Snellen chart, but with slight difficulty.
My cm measurements (average over 3 days, taken 3 times per day): R-13, L-13.1, Both-13.7.
My question is how do I figure out my close up glass prescription? Do I base it on my latest prescription or the glasses I am wearing? Do I take more cm measurements to support my decision? What do I do about the astigmatism? I tried some reading glasses (+1 & +1.5) on top of my current glasses and really not sure having 2 glasses on top of each other is helping me figure things out. I do have contact lens at R (sph:-7.50, Cyl:-1.25, Axis:170) & L (sph:-7.50, Cyl:-1.25, Axis:10) which I can try the reading glasses with. However, not sure how to interpret the results?
I have glasses from 2014 that I could wear, but this is not that different, R (sph:-8.50, Cyl:-1.75, Axis:177) & L (sph:-8.50, Cyl:-1.25, Axis:10).
Sorry for the long message and look forward to your response. My first time using the forum, so apologies if this is in the wrong place to be posting things, if so please point me in the right direction.
