Cheapest Chinese Prescription Lenses

Can anyone recommend a cheap source of prescription lens blanks from China? I am short sighted and have taken to making my own cycling glasses, e.g. like this,
Imgur
by bolting prescription lenses to the front of very cheap non-prescription specs. Ugly perhaps but effective.

Background blurb. This is the only forum I know of where folks talk about buying stuff from (generally but not always) China. I guess that any forum where this is a topic of conversation must be administrative hell, due to the all the spam that is likely to arrive from sellers. Thanks to the administrators for keep this place relatively free of spam, and yet, amazingly, allowing responsible sellers to have a voice - the review by the seller of the Javelot? long through light was interesting. Thanks to the administrators.

Actually we have just one admin. Most spam is dealt with by users through the “Mark as SPAM” link under each post. If a post receives enough spam reports it will automatically be hidden.

How much was the price of the prescription lens blanks in your picture and where did you manage to find them?

I don’t know any source for lens blanks but I have used http://www.zennioptical.com/ and they have very inexpensive prescription glasses. One option would be to get a cheap frame with large lenses, take out the lenses and toss the frame.

I’ve used Zenni for one pair, got “computer glasses” from them.

Okay lenses as far as I can tell by wearing them, haven’t had an optometrist check them.
My only worry was the earpieces, which had spear points on them where they sit over the ears.
I was afraid if I whipped the glasses up to put them on quickly I might could poke my eyes out.

The lenses shown were from my optician in Japan. For quite a while I have paid an optician to put strangely elongated lenses into cheap (100 yen shop) frames.

But the frames, being cheap and for reading broke, and then I would have to pay the optician to make lenses for another pair.The lenses cost about 30-35USD per pair from a local optician. It is not a lot, but I was purchasing a pair every three months.

Then I got some half frame glasses from aliexpress but they did not last long either

Then I realised that the lenses do not need to fit the frames if I just bolt the lenses on the front of cheap prescription free lenses. The fact that the non prescription cheapo lenses, tinted or not, are still in the frame makes the frame stronger. The line in the middle of the glasses is not so much of a problem because I am generally looking out of the top. When the glasses break I can just drill holes in the lenses of another cheap pair of 100 yen (sun)glasses.

I can get 5 usd glasses from ebay (search for nerd glasses on ebay) but the prescriptions have to be symmetrical (my eyes are –2.5 –3.0 so –3.0 –3.0 is usable) and the paint comes off the frames. The glasses are made with lenses to fit. I am sure that they are no big round blanks.

I can get 25 USD lenses and frames (the set) from aliexpress, again in “nerd” shape to my prescription (I have no astigmatism) from Aliexpress, and this is the cheapest that I have bought lenses.

But then rearranging the aliexpress keyword search for prescription lenses, with free shipping, and only one item (i.e. not in bulk) the cheapest are $2 but I think that that is a $2 surcharge on on some other glasses/frames and not the cost of the blanks.

The cheapest that do not look like they are a surcharge (i.e. one can just buy the round blanks) are about 8USD per lens e.g.

I use them because I like to get horizontal when I ride my road bike and look out the top of my brows, without craning my neck up. I am not that fast, but horizontal is fun and is an incentive to stay thin. I can only get horizontal recently, and it is a battle to stay thin. Going horizontal is the carrot. Cycling glasses come up high but have tiny RX inserts. Billards glasses (google) would also work but they are bout 150 a pair. My glasses get caught up in my helment straps so I want cheap or durable.

I could use a hacksaw or an angler grinder to cut the lenses but ideally I would like them to be cut to the shape that I want.

My optician confirmed when I asked that they can make “upside down” bifocals, and do it routinely for people who spend a lot of time working close underneath things — plumbers and electricians. I asked because I’d been trying to do that working in a crawlspace taping my cheap reading glasses to my forehead over my regular glasses ….

I willl be needing bifocals soon, but for the time being I am considering bolting the lenses to my cheap frames such that there is a space at the botom where I am lookin through the non-presciption plastic of the cheap glasses. These days I have to take off my specs to read things close to my face.

I honestly didn’t know such options existed. I suppose I shouldn’t be surprised. This is great info. Glasses can be too expensive.

I have used Goggles4U (.com).

I have 2 pairs of glasses from them, purchased at different times.
If you get on their email list, they occasionally send out fantastic coupons (usually on holidays, like FourSevens).

The thing with them is, you will probably end up ordering several pairs over time, as each time, you learn more, and get better at ordering. At first, you don’t know if you need wide, medium, or narrow glasses. The most difficult part is calculating your the distance between your pupils. They have a default you can use, if you don’t know. A friend I tasked with measuring my pupillary distance with both a ruler and calipers, was unable to do so (gave up after giving me unrealistic, and different, numbers on 2 tries). I had to try to do it in the mirror—not recommended. My years-old prescription paper does not list my pupillary distance, unfortunately.

I became of the opinion that continuing to get stronger and stronger prescription, is a vicious cycle. I have proven that to myself. I could use a stronger prescription, but also my eyesight has not gotten any worse over the years. I actually feel like I didn’t need glasses when my parents forced me to start wearing them. And I believe my vision would be much better today, if I could have put off wearing glasses as long as I wanted to.

Years ago, Goggles4U had more ‘normal’ looking frames. The ones I have seen lately (haven’t visited in awhile, kind of gave up for this reason), are overly stylized (I think bizarre looking), and geared towards what they call “designer” frames. I am glad I got the two I did, when I could. Even those, are IMO a little overly retro or “hippie”, which style has been foisted on us for years, and still has not gone away.

When I saw how cheap some of the G4U stuff can be, I concluded that most of the cost of glasses from glasses stores, was not the product, but the overhead of keeping a building, employees, etc… I think the actual product is probably the smallest expense a glasses store has. One valuable service a glasses shop does provide, is setting the glasses up for you (nose pad alignment, ear curve). And of course being able to try different frames to see how they look and feel. But when I go into a glasses store, I don’t like any of the styles anyway. I prefer to buy things online anyway, but I’m unusual. And I cannot tell a difference in construction quality of G4U versus store frames.

Goggles4U has a number of options, including re-lensing your old glasses, though I would be hesitant to send any irreplaceable frames to them. I believe they will ship bare lenses (blanks) to you, like you asked. Another purpose for doing that would be snorkelers and SCUBA divers. There are diving masks where whole blanks can be fitted. I have seen them in dive shops years ago. I was shocked to see how California, USA effectively made prescription diving masks illegal, by forcing all lenses and glasses to be purchased from an ‘authorized’ eyeglass store. The California dive shops woud sell those dive masks, nor would they fit lenses for you, even if you had them. Outside of California, getting them not a problem. Seriously people, socialism is the devil. It was also illegal for dollar stores in CA to sell those cheap-but-good reading glasses for farsighted people. The optometrist industry also somehow got pinhole glasses nationally outlawed. Pinhole glasses work, no prescription needed, but all the ones I’ve seen, like on Ebay, the holes are too big, so they don’t work right. If they are truly the size of pinholes, they do work, and it is amazing. You get a glimpse of how much helpful products or technologies have been suppressed, because they were too simple, too inexpensive, and too effective.

The last time I got a lens prescription, I asked for a copy of it. Everyone should do this, just to have it. You might need it someday. In CA, they might refuse that, I’m not sure.

I have no affiliation with G4U, and again, wish they would re-expand their selection of lower-cost frames. They had a number of nice, more normal-looking, very inexpensive frames that sold out, which they unfortunately never re-stocked.

PS I really like the idea of cheap, custom prescription cycling glasses! Let us know how it goes—please!

Thank you. I had a look at Goggles4U. There was one cheap (7USD) frame which is 17USD delivered to where I am but it is weird. The more standard frames are 20USD 30USD delivered, which is about the same as the cheapest glasses at a local optician, and about 5USD more than ones from Aliexpress.

Speaking of Goggles, I also got some goggles from aliexpress at about 28USD.

The lenses were 15USD on top of the price of the goggles themselves

I have asked the first aliexpress seller I mentioned above about oblong blanks like the ones I am using
Imgur
but I also found out my optician is only charging 20USD per pair (cheapest, no coating, not so strong) so there is a good chance that I will ask them.

I don’t notice the bolts (M2 @ 8-10mm with washers and lock nuts included in the pack) when I am riding. There where some comfortable frameless sunglasses glasses at a local second hand store, only lightly tinted. I may bolt some prescription lenses on the front of them. I would not wear them to work, but for cycling, where no one sees me, and there is no commercially available alternative (other than billiards glasses), so bolting on is the way to go for me.

These are matrix sunglasses. I won’t be using them (already dismantled) but they show anything is possible.

The seller at
http://www.aliexpress.com/w/wholesale-prescription-lenses.html?site=glo&groupsort=1&SortType=price_asc&SearchText=prescription+lenses&initiative_id=AS_20150719013348&shipCountry=JP&similar_style=n&isRtl=yes&isFreeShip=y
agreed to sell oblong blanks at my prescription for 13USD per pair or $25.5 for two pairs. I have ordered and will report back eventually (usually takes about three weeks). If you order please mention my name. His name is Zach apparently.

Wow, that’s some really thought-provoking stuff.

The ‘Ikey 493 basketball glasses’, which you appear to be wearing in your flikr photo: how does it work to order them? Does that listing only include the frame, and then you have to click on the embedded link and simultaneously order lenses, or how do they know to fit that 2nd order into the 1st glasses?

It also appeared you would also put your prescription in the comments for the lenses when ordering. I would just want to make sure that they knew to mount the ordered lenses inside the goggles.

Do you like those Ikey goggles? It looks like you’re obviously looking for something different for cycling. I don’t know anything about cycling glasses, so for me, I guess everyone, it’s about keeping the wind and dust out of my eyes. I guess like you, my normal glasses lenses are a bit small, so it lets the wind past the lenses too much. I have considered trying shooting safety glasses or even regular hardware store safety goggles over my glasses while riding, though the latter would be really embarrassing. It sucks to get something in your eye, though, especially at speed. I’ve also considered affixing/bending a piece of transparent plastic over a bike or BMX helmet, like a visor/shield.

Interesting… thanks for posting.

And it sounds like G4U has continued to go downhill since I was there quite awhile ago. Seems like they’re deliberately trying to sell out of their budget frames, sorry. I’m glad I ordered mine when I did, several years ago now (wearing one now). What I got was good enough for me. The last time I went back, I saw nothing I’d consider ordering :frowning: . I keep hoping they’ll figure it out and go back to what they used to stock, but it just gets worse.

I had quite a lot of problems with ordering the prescription lenses for the goggles. The top guy selling them said yes okay, I’ll have them fitted with prescription lenses. Make a purchase. Don’t make payment. Let me know and I will put up the price by 15USD and fit them up. I did all this, and told them my pupilary distance and prescription but when the glasses arrived they had standard lenses. I wrote and said that I would not pay (aliexpress has a protection thing that you need to say you have received the goods before the seller gets payment) unless they sent prescription lenses. After a lot of to and fro they send the lenses and I put them in. The problem with that seller is that there are many people working at the shop. He may require more than 15USD to want to do it again. I think that if when one makes purchase one adds a prominent message emphasising ones intention to have them fitted with precription lenses then it may work. If not then try another seller.

The goggles are good. I wear them when I do karate (badly!).

I like to ride long and low - almost flat backed - on my bike, for fun, and the goggle frames get in the way. I think that for people in most riding positions the goggles would be fine. I recommend them - but perhaps not from the above seller. I find that for $20 one can get a local optician to fit normal un-tinted lenses into a frame so that may be the way to go.

For those that want to go long and low, I would still also recommend purchasing some oblong blanks and bolting them to a variety of cheap glasses of your choice. One can pick up rimless glasses second hand cheaply. There are sunglasses from $1.2 on aliexpress which I have also ordered. I may remove the top part of the frame, glue the lenses into the sides of the frame with super-glue and then bolt blanks on them.

There are also these rimless sunglasses for $17. They’d be easy to bolt to.

Get good readers for yourself instead of lens. Readers are easy to wear and easy to carry and maintain. You can read more about this.

I suspect you’d have to be very particular as to how you bolted the lenses on, to maintain the pupillary distance. Aren’t you better off getting very slender spectacles and adapt or even make your own nose piece so the lenses sit much higher? Or even, thinking laterally, create a simple mirror/periscope set-up to sit beneath your normally fitted glasses if you’re riding “flat”, then your viewing angle (which would be very weird at first I bet, but you’d soon get used to it) would be fine?

Interesting thought, and the product already exists!

They’re glasses advertised for reading while laying flat on your back. :smiley:

EDIT: On second thought, these might prove dangerous when you tilt your head up and are suddenly looking straight up into the sky! :person_facepalming:

Yes I did cinsider prisms which can be had cheapky as lazy glasses on ali/ebay, and there was an abortive kickstarter but I want a wide field of vision. I found that bolt ons were okay on dry days in winter but, in the wet or sweat, fluid would get between the lenses so I did as you suggest and got some strong thin double screw readers with Trivex lenses from aliexpress and wear them all the time on my bike.

I still look like a dork though.
