Hello everyone!
I was wondering if someone could post a table of diopter power correlated to visual acuity (20/20, 20/100, 20/600, etc). Please post for PLUS power lenses, I will post one below I found online, it is for MINUS power lenses.
I understand that these are only approximations, and that's just fine.
My glasses are +11.00 OU, single vision and no astig. I know I'm off the charts, but I'm curions to learn my VA, unaided, given my prescription.
I also read that the chart for MINUS is not equivalent to a PLUS power. That is, if a person wearing a -5.00 has unaided VA of 20/500, this does not mean
that someone wearing a +5.00 will have unaided VA of 20/500 as well.
Is there a formula to estimate VA for PLUS power, given the diopter used?
Please post a chart like the one below, but for PLUS rx's.
Tnx :nerd:

- These approximations apply to nearsighted (myopia) patients wearing glasses.
