Question
In May '09 - my prescription was
R - sph -0.75 -- cyl +0.75 -- axis 021
L - sph -0.62 -- cyl +0.75 -- axis 160
with a reading addition of +1.50
Insurance changed and new Dr. gave me this prescription
R - sph -025 -- cyl -075 -- axis 105
L - sph pl -- cyl -1.00 -- axis 065
with a reading addition of +125
I didn't have problems with my previous eye prescription - is it possible to have a change like that in only 8 months?
Answer
This is NOT a weird change in prescription. You obviously don't know how to read prescriptions nor tell what the differences are. The presciptions you listed are actually fairly similar: one being written in plus cylinder form and the latter being written in minus cylinder form. Usualy, the former type of Rx is written by ophthalmologists and the latter by optometric physicians. For example an Rx of +1.00 = +1.00 cx 90 is the exact prescription as Plano = -1.00 cx 180. Make any sense? If not, it took me a year of ophthalmic optics in Grad school to learn it.
Hope this helps. Dr. Ken
PS You've assumed that because the numbers are different that you've either encountered "a weird change in prescription", or a large "change in only eight months". Neither is true , as I explained, because of two presriptions that are written differently. This is akin to water vs. H2O, Both are the same but wriiten for in different forms. Hope this clarifies your understanding of your situation
