Is it possible to check astigmatism prescription by lenses??
Question: you have glasses
you don't know what prescription they were made according to
you go to an optometrist and ask them to check
can they know whether the lens is also for astigmatism?
and can they tell what the prescription was?
Answers: YES! Any optical or optometrist's office should have a lensometer of some sort to check your prescription. they can read your astigmatism correction right off your lenses exact numbers.
most prescriptions read as follows (the numbers are just an example)... it's a table... use your imaginations! lol!
.......................Sphere ...Cylinder .. Axis
OD (right eye) +.50.......-1.50........070
OS (left eye) +.75.......-1.00......114
the numbers under the cylinder would be your astigmatism correction.
ask the optician to write it down for you on a post-it just so you have it, or call your eye doctor and get a copy of your prescription sent to you.
They should be able to. They shine light through the lenses and measure the way it bends. I'd call ahead first, though, since some places might not have that machine.
They would probably be able to. When I get an eye exam, they gauge the prescription of my lenses.
Wouldn't it be easier to obtain a copy of the prescription from when you last had an eye exam?
All optical stores and eye doctors can measure the prescription of your current glasses.
