Can an Eye Doctor Tell You Your Contact Lens Prescription by Just Looking at Your Glasses?
March 25th, 2010 | See the Top Answers to this Question Below
Because I went to an eye doctor a few months ago and she just looked at my reading glasses and told me my prescription was -2.00 but then I went again but to another eye doctor because my insurance changed and she did and eye exam and told me my contact lens prescription was -3.00 but I can’t see with those contacts.

they usually take your glasses, does a measurement with your glasses with a measuring instrument, then begin the eye exam based on the existing measurement of your glasses.
yes, i think so
the really mean is not "just looking" with naked eyes, but they seems to have some like " microscope " but not real microscope to measure your glasses. this is what happened in my country, Indonesia , which is developing country. Probably in yours, it might be much better.
but , it sould be any test again, expecially by " chart of snellen / straub " before writing contact lens prescription , just to make sure and to recheck weather the meansurement is the same as the " microscop" did or not. Bu if didn’t , GP would use the snellen/straub chart measurement for exact prescription
Yea they use this microsope thingy to measure it
They can look at your glasses and get an idea of the prescription, but contact lens prescriptions can differ – my spectacle and contact prescriptions are very different.
