Is it possiable my script to change this much over 2 years
Old one
Sph cly axis
Od +100 -100 110

Os -100 -50 75

New one
Od +75 +100 25

Os +75 +75 170

Looks like big changes to me... I didn't have the old script fot the dr to look at he started from Q 1
Thanks for your input and help... richard

Are you sure the first script reads OS -100?

Your vision got worse by about a 25% change in focal length.

From 0.393" to 0.524"

I don't buy the -100 to +75 change.

The other numbers are for Astigmatism corrections. OD is right eye and OS is for the left eye.

The script is written in Diopters and 1/D = focal length in meters. So, convert 1/75 and 1/100 meters to inches.
A minus is nearsighted and a plus is farsighted.

Yes, your vision can change large amounts over 2 years, in fact that is why they want you to have it checked at least once a year.

Ty... yes I read the scripts correct... this kind of change is possiable? Tks... richard

That prescription needs to be transposed. And once it is, your vision hasn't changed too much.

If your sphere is a plus and your astigmatism is as well, then its written to be transposed. So, your vision hasn't changed more than a quarter diopter, and that's not bad AT ALL. That's a minimal change.
