I am trying to work out my first differentials, but there are a couple of complicating factors, namely, presbyopia and cataract, plus the added inconvenience of not being able to get out to try plus lenses in a store due to the current stay-at-home restrictions here.
My last optometrist script was in November 2019:
R: -11.75 (-1.5 cyl)
L: -12.00 (-0.50 cyl)
These are my current glasses. I was also suggested to get +0.75 reading glasses which I didn’t get.
December 2020: The optometrist said I had a cataract in the right eye and because I couldn’t see the Snellen chart clearly with any of the lenses she used, she didn’t give me a script. I was told to go and get cataract surgery in the right eye and then come back. So now I have an ophthalmologist appointment in a week to discuss surgery.
Cm average is L: 11 and R: 8
Snellen Chart (with current glasses at 3m) - I can’t see anything clearly with the right eye. Left eye: 20/15.
Close up habits: A couple of hours a day at an ergonomic distance of 50cm, if that, mainly researching and watching videos for Endmyopia.
Question 1: In the absence of a current prescription, does it sound sensible to calculate my diopters from my cm readings and start with a 0.5 diopter reduction in each eye?
Question 2: Does anyone have any recommendations for a friendly optometrist in London or surrounds. It would really help us out while we can’t get out to try plus lenses (my 13-year-old son is doing this with me).
Thank you so much.
