  5. May 30 -8 R 20/30 triple vision L 20/20 double vision, too bad vision, occasionally damaged it and threw out

Last exam Jul 24
Autorefractor for contact lenses
R -8/-2.75
L -8.5/-1.75

Prescription
R 20/40-20/30 -9.75/-1.5
L 20/20 -9.75/-1.5

I consider buying new glasses either:

  • Full correction or reduce sph by 0.5 (-8.5/-9): R -9/-3.5 L -9.5/-2, isn’t too expensive due to R cyl
  • Equalize to R SE: -9.5/-1.5 (left eye seem to need only 1.25 cyl)
  • Equalize to R reduced cyl and L reduced sph: -9/-1.5 or -9/-2
  • A sort of compromise (equal): -9/-2.5
  • Or not equal: R -9/-2.5 (-3) L -9/-2 (-2.5)

Am I fine to use eg “equalize to R reduced cyl…” when I see in that ≥20/30-20/50, despite I undercorrect say right vertical meridian by 1-1.5 diopters or correction is not equal that one eye sees better/different than other? I may cheat with eye chart and it’s 5 m in OD’s office instead of 6, so how to not cheat (say if you see severe double vision or line is not perfectly readable) and choose quite adequate correction I will not disapprove week after because it’s too hard to see in that or not change it after 2-3 weeks because it was only one line less than 20/20? How to convert results of 5 m eye chart to 6 m one?

You are good to throw out.

I still have all of mine LOL
I think I am scared I will regress!
