Nearly 200 posts, and now you have a new question? Did you try any of the conversion formulas in this thread?

Default my prescription

Hey guys.. love to have some feed back on what my new contacts should be.

Old contacts
Left Right:
BC:8.70 8.70
SPH:-2.50 -3.00
CYL:-1.75 -1.75
AX: 100 70

I have now got new glasses which are as follows
Left Right
Sph: -3.50 -3.25
Cyl: -1.50 -1.25
Axis: 80 80

If someone could tell me what my new contacts should be now that would be great...

If someone comes here and tells you that your new contact lens prescription is -X.XX, what then? Write it down on a piece of notebook paper and bring it to your doctor's office? Do you know what she's going to say then? "Sit down in the chair and let's just make sure those numbers are correct."

Lens 101 is a great website, and it's useful for many, many things, but handing out prescriptions is not one of them.

Most eye professionals who prescribe contacts will give you a script for glasses at no extra cost. The reverse isn't true. A contact lens exam is frequently more expensive then an exam for regular glasses.

Contacts are available in fixed paramters. -7.0 -7.5 -8.0 for example. You don't know if your doctor rounded up or rounded down. Your script might have changed since your last exam.

Your eyeglass script will be similar, maybe a little less, then your contact lens script.

Are you due for an exam? Get both scripts at once. Did you just get an exam? Go back an ask for an eyeglass script.

Those are very good suggestions, lurker2010. There's no substitute for a professional eye exam and fitting. If you want to wear glasses or contact lenses, then you have to get fitted for them. I don't see any other viable alternative.

There are a number of internet sites which sell glasses. I suspect, but I hope I'm wrong, the poster wants to purchase glasses without a script.

There are ways to "fudge" your script and order contacts on the internet. I suspect, but hope I'm wrong, posters who ask for help converting an eyeglass script to a contact lens script plan on ordering contacts without a valid script.

A previous poster made a great point. An eye doctor prescribing contacts has no interest in the conversion done by a poster in an internet site.

I think you're right about onionpatch51's original posting. Especially the part that said "they don't have to be perfect." If I was going to get a prescription for either glasses or contacts, I'd want it to be as close to perfect as possible.

You're right about that, SteveKemp. I would never settle for an imperfect contact lens prescription, no matter how much money I could save.

I agree, lurker2010. An eye doctor who really cares about their patients will not just go by a prescription that was obtained from the Internet.

One thing that reduces the "fudge factor" would be that any reputable contact lens dealer will contact the eye doctor and confirm the prescription. Hopefully things will stop when the doctor says "I never prescribed those contact lenses to Miss Brown."


Mmmmmm . . . fudge . . .

I'm glad you agree with me, unclebuck. It just doesn't make sense to get cheap lenses if they don't work as well. If you need contacts, they should do what you want them to do.

Reputable contact lens dealers want to sell lenses. A reputable dealer will follow the requirements of the Fairness to contact lens consumers act. Nothing more and nothing less. It's is easy to either find an internet vendor who doesn't follow the requirements or to fudge your script I'm not going to make this a "how to do it" post. If you care use google.

Hopefully this thread has made it clear by now that if you want to get a prescription for a pair of contact lenses, the best thing is to let your eye care professional handle it and not try it on your own.

Right. I got it. That makes sense to me, and it's what I thought even before I read this thread. See your eye doctor before you do anything, kids.

Absolutely. I would never try and write up a fake prescription. Not only am I a law-abiding citizen in general, but I have a hard time lying. I have a terrible poker face.

Never play cards while wearing mirror sunglasses, kids.

Yeah, some people wear sunglasses to hide their eyes, but mirror sunglasses brings up a whole new problem.

I can't imagine what would motivate someone to try and forge a contact lens prescription.

To paraphrase the Fourth Doctor: "people who forge contact lens prescriptions don't usually work for love." On other words, there's probably money to be made.

Good quote, and I agree. Another monetary motivation would be the desire to save money by not paying for something.
