Clear Rx cycling glasses?

I'd like a cheap set of the usual Oakley knockoff type glasses. Something that looks like this:





But with clear lenses, single-prescription. Is there anything like that out there for cheap?

That's three things. Cheap. Prescription. Sports. You can have any two.

Is there something about being "sports" that makes it more expensive? The frame seems much simpler than most regular eyeglasses, and a big single poly lens shouldn't be that much.

Yes, the frame and lenses are much more specialized. They can't just grind the lenses like they do with regular glasses. Go to any optometrist and ask to see the prices on their sporty prescription glasses. They're outrageous.

I am sure you can find a "cheap" pair of sports type glasses on-line. However, I think that depends on what you consider to be "cheap". Just do not come back on Bike Forums complaining that you were cheated because you did not get the item and quality you were expecting.

Ebay - Interchangeable lens
Amazon Prime - interchangeable lens
Amazon - Stick on lens
I used the stick on lens until I got a re-cycled eye. Works pretty good if low power reading lens is what you need

An interesting thing is there seem to be about a half dozen near-sighted lenses that are frequently sold over-the-counter. It is not uncommon for elderly folks to share reading glasses to read a menu at a restaurant.

Pure far-sighted lenses might also typically be in a dozen stock sizes. Frequently prescribed with different prescriptions per eye, but there is no reason why one couldn't have off-the-shelf generic far-sighted lenses.

It becomes more complex when one includes astigmatism (different vertical/horizontal focal lengths), and bifocals/trifocals.

I presume that the reason why some companies can advertise very cheap glasses is that they aren't actually custom grinding the lenses, but rather using plug and play lenses.

I'm surprised it can't be done with sports lenses to some extent, but perhaps the limited market makes it difficult. Plus, the wide viewing angles that are often chosen may make custom lenses more difficult.

One could, of course, use the Fresnel concept that is used with light houses as well as many flat screens including vintage projection TVs, but it may be annoying to have extra lines in the lenses, and more difficult to keep them clean.

I think I've seen sports glasses that mount a small corrected lens behind the large sweeping sunglasses lens. Not my choice, but truthfully, I have reasonably good peripheral vision around the edges of my glasses, so perhaps it wouldn't be such a problem as it may seem.

I picked up a pair of Ridge CF SM from Safetygearpro.com about two years ago, and they're perfectly serviceable single-vision glasses for riding. Will all of my options and adds (high-index polycarbonate lenses, ant-scratch, anti-glare,) my pair came to about 80 bucks, which is really cheap. Safetygearpro runs pretty fast and loose, too-- they have no form to submit a prescription or anything. You just type the numbers (sphere, cylinder, axis, pupillary distance) into the fields and they send you glasses. Fast, too. I got them in 6-7 days from date of order.

Try looking at www.zenni.com. I bought my glasses there. Not the big names but the price was good.

The best knock off Oakley’s are Oakley’s.

Go see an optician and have what you want made. You won’t regret it.

i agree i had Zenni but they were RX insert behind lenses and they fogged up all the time. I bought Oakley clear and sunglasses and they are expensive but totally worth it.

Interestingly, the picture in the OP is that style--you can see the faint outline of the prescription glasses behind the sunglass visor.

I just checked--OP got the image off of the Zenni site.

Yes I found they fogged a lot. I found myself popping out the rx insert and using the front lense it cleared up. my oakleys don't fog near as often,.

Yeah, I want that look but 1) clear, not tinted, and 2) the whole lens is Rx, not just a shield in front of small Rx lenses.

The reason I want cheap ones is because these are, believe it or not, just for watching movies at home. I can't stand having rims in my peripheral vision so I want as big a lens as possible, and don't need polarization, scratch resistance, de-fogging, etc. Goofy, I know.

For biking I use Costco "Drivewear" Rx sunglasses with a croakie to keep them tight. Work fine.
