Thread: Contact lens prescription to eyeglass prescription

  1. #1

    Default Contact lens prescription to eyeglass prescription

    My prescription for contacts is -1.75, is it possible to convert that to an eyeglass prescription? Thank you for your help.

    Yes, it is possible. There are at least two or three threads on Lens 101 that tell you how to make the conversion, or at least what website you can go to for you to plug in your contact lens prescription and convert it.

    Before I tell you where to find that information, I want to mention that someone on this site made and interesting point. If you calculate your own prescription, then bring it in to your doctor's office, I doubt if he or she will say "Hey, thanks. That saves me some work!" No, they'll probably measure your eyes anyway to confirm your calculations. Doctors are kind of funny that way.

    At any rate, here's that thread: http://www.lens101.com/introductions/125581-help-my-perscription.html

    That's a good point, HelpMeRhonda. It seems to me that figuring out my own contact lens prescription based on my glasses prescription looks like a lot of work, and when I was done I still wouldn't be sure it was correct. I think it would just be a lot easier to let my eye doctor do the measurements. That why we pay them the big bucks, right?

    Exactly. It's not like you go to the eye doctor and he charges you extra to calculate your prescription. It's part of the job. I wonder how many people would go to get their oil changed and hand the mechanic an oil filter, a jack and a socket set and say "Here, you'll need these"?

    (You try finding a picture with just those three items, or even two of them. )

    It would be even worse if you were to show all that to the mechanic. "Here yo go. Don't spill anything."

    I agree Logopolis. I'm not very good at math anyway. You should see my check book.

    Yes of course it can be converted but legally we need a copy of your present(less than 2yrs old) eye glass prescription.

    Yes, you still need a prescription signed by your doctor in order to buy contact lenses. If a contact lens seller tells you that they don't need to see your prescription . . . move along.
