Rx Glasses Adjustment?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.

Rx Glasses Adjustment?

I got Rx for -4.75 on one eye and -2.25 on another one.
Unfortunately, the Oakley Jawbone, frame that I already have will fit lenses -4.00 if I am not mistaken

I already have glasses with Rx insert, but I would like to get Jawbones too.

Do you know if I can adjust one eye prescription to -4.00 to have it fit?

and what is the best place to order just lenses?

Thanks!

Your best bet, I think, is an optometrist. A friend of mine is one, and as a cyclist he understands cyclists' particular wants and needs. My eyes are not good enough for Oakleys but he worked hard to optimize my glasses for seeing traffic, the bike computer (which I realized after the fact that it isn't that important to me), and not feeling woozy (due to bifocal type lenses).

We've discussed Oakleys and similar (he's a dealer for a few sports glasses). He said that optometrists can sometimes get a wider range of Rx versus what's advertised. I don't remember looking at Jawbones in particular but I'm pretty sure that some regular Oakleys can go to -6 or so. Last time I got glasses was a few years ago and I honestly don't remember.

Once you pay an optometrist for their expertise/sources once then you can replicate the lens/glasses as you wish.

As a bonus he can double/quadruple check your prescription. My optometrist friend has some laser gizmo and it took about a minute to figure out my eyes actually did get worse. I remember now, I went because I couldn't see my infant son's nails well enough to cut them, so that makes it 2 1/2 years ago.

Hope this helps.

Thanks for detailed reply, it really helps.
But there is an issue with optometrisrt, I talked to one, and she said, no, I cannot adjust my prescription. I believe this is a liability issue, and she did not want me to have glasses less than prescribed. In case something happen, she thinks she is liable for giving me wrong advise.


But from my experience, I know, I CAN wear less powerful lenses. Because I still have my old-old glasses, and they are fine. Not perfect like my current prescription, but good enough to ride.

So, I have to find a place where they can adjust my prescription. Or adjust the lens bevel with Dremel to fit. I could not find such place where they can work with me. If someone knows it, please, let me know.

First, I'm not an optometrist and I haven't asked my optometrist friend about this.

With that in mind I want to clarify something. I think that you should be able to get a true -4.75 prescription lens for the Jawbones.

When I went to the optometrist Oakley had certain Rx limitations listed on their website. However the optometrist stated that in fact the limitations were higher with Oakley lenses and that he could get even higher (lower?) Rx lenses for the same frames, meaning through whatever normal stuff they get and then grind for fit. I think at the time I was looking at Jawbones, maybe something else, I don't remember the actual model name. At any rate the limitations were -6, not -4, and that was probably 4-5 years ago, the last time I thought about a sports glasses. Since my eyes are worse I couldn't take advantage of even the -6 Rx.

In other words, if you actually go see an optometrist (if you haven't already recently) they may be able to help you out.

btw I'm not saying the optometrist is free. I could have bought a pair of Zipp carbon wheels for the price I paid for 1.5 glasses (two sets lenses, one for a new frame, one ground to fit a frame I already had), and this was after another pair plus of Zipp wheels' worth of professional/friendly discount.
