This is Part 5 of my multipart review How to buy glasses online. I have already posted my reviews of DB Vision, Warby Parker and This recap and summary is my final post which completes the series.

So far I have introduced the predicament of buying glasses with high index lenses in a monopolized glasses market, and reviewed my online shopping experience at three web-based optical retailers: DB Vision, Warby Parker and Along the way I have attempted to provide objective reviews of these retailers based on my personal experiences as well as advice for anyone considering buying high index glasses online.

Review summary

For this post, I intended to rank my three purchases and pick my standout favorite. That turned out to be more difficult than I thought. Instead, I'll finish with a brief summary and the pros and cons of each pair. This will supplement my earlier reviews now that I have had the time to wear each pair for a longer period.

I now have 3 pairs of glasses from The first, subject of Part 2 of this review, are designer frames with 1.74 high-index lenses. The second are the same frame with 1.67 lenses and are slightly defective. I was allowed to keep them after requesting a fourth replacement order. The third, not mentioned in this review until now, are a pair of computer glasses, also designer frames, with 1.67 high-index lenses that I purchased using the complimentary $100 credit provided by for the inconvenience of messing up my first order so many times.

Pair 1 took forever to get right and the lens package I ended up receiving is not available on the website because they were upgraded by special order (for free). Since I had tried these glasses on at several opticians and ordered them before any others, I assumed that these would be my favorites and this was also my rationale for investing more money in them ($248; $183 after discounts). To be honest, I love the pair with 1.74 lenses, but it is an unfair comparison against the other companies since 1.74s are not even available on-site. While I also love the frames alone, they are not as robust as I had hoped. My new computer glasses also have a somewhat weaker frame than I feel they should for the retail price. Perhaps that is not entirely’s fault. It is the fault of costly designer frames not being made like they used to be; and you would get the same exact frames at, say, Pearle Vision. Still, they are more delicate than I had hoped.

That said, upon first ordering, I was also not happy with the lens coatings and vision clarity on the premium lens package from, nor the highly polished edges, which led to many returns. While they happily obliged my returns, it began to border on the ridiculous, hence all the compensation (a full refund and $100 credit). My second order - for computer glasses - went smoothly: I got a personal call back to let me know that the order was placed and they even upgraded me to a premium lens package free of charge. So with the $100 credit I had on my account, I paid nothing for my computer glasses, either. Alas, the first pair had to go back (I thought it was a problem with the lens weight, but now I feel it was a faulty frame), but the replacement pair is perfect.

I have mixed feelings about In total they have given me 3 pairs of glasses with a retail value of almost $1000 for my trouble. I was ultimately happy with both the distance and computer glasses and got a backup pair thrown in. I can't top the customer service I received when things went wrong ... but so many things went wrong. The imperfect quality of the lenses and tendency for the frames to arrive defective has me worried.

Pros: Very good and patient customer service; Good selection of designer frames; Coupons and discounts available; Exceptional returns policy

Cons: Higher prices than other sites; Defects common (in my experience)

Warby Parker

I loved my Warby Parker glasses right out of the box. The frames felt strong, the color was great and the lenses gave me exceptionally clear vision. They instantly rose to the top of my list as my favorite glasses ever, above all because of the clarity of vision and instant comfort. When switching between glasses, they still give me the least feeling of needing to "adjust" my eyes and never make me dizzy. Although the tips of the stems feel a little tight on my head, the lenses feel so natural that I can forget I am wearing glasses.

I wore them for the first week or so after I got them, but then switched to the other glasses in this review as they arrived to test them all out. I put my Warby Parkers on again this week for the first time after a long gap. The clarity of vision is still perfect, but there are a couple of reasons why they are no longer my absolute favorites. First, they're a real pain to clean. After using plenty of lens solution and a microfiber cloth, when I hold them up to the light there is still a ring around the lens on the inside and outside of the frame which is impossible to get completely clean. I have had glasses since I was a kid and I am at a loss as to how to clean these. Second, I have noticed that on the tip of one stem there is tiny mark in the plastic surface as if it's peeling. I didn't even realize they were coated with something on the surface and I hope it doesn't get worse. Since I've hardly worn them, that is a bit worrying. Also, when I place them on the table, the stems are uneven. I don't believe this was the case when they first arrived. Since I meticulously return them to their case wrapped delicately in a microfiber cloth after each use, all I can presume is that they mold to your head as you wear them. Lastly, after a few days of wear, the lenses seemed to have settled into the frame and they may not be as accurately cut around the edge as I first thought and reported. No one would probably notice but me, but the right side lens has a dark patch along the bottom edge because of the way it has been cut.

Pros: Fixed, fair prices; Charity program; Best standard polycarbonate lenses; Great frame collection (metal frames now available, too).

Cons: Hard to clean; Long-term quality TBD.

DB Vision

DB Vision offered me a complimentary pair of their digital glasses. It took me four in-home trials to arrive at a pair of frames. My hopes were not high, since I knew nothing about the brand new company, was skeptical about the digital lenses and had trouble deciding on a frame that fit. As it turns out, I love the frames and the digital lenses. The clarity of the lens is fantastic, even in a frame with a much larger lens than I thought I could wear given my Rx (see below). Even though they are also plastic frames with 1.67 lenses, they are easier to clean than my Warby Parkers and show no signs of wear. All told, I have worn these the most often, making them my unexpected favorites.

Pros: Digital lenses provide exceptional range of vision; High-quality frame with sprung hinges

Cons: Prices have jumped astronomically (see revised table below); Most frames too large for me

Well, that about concludes my review, except for one last bit of advice about Frame PD, a factor that is lacking from most online buying tutorials I have seen.

A final word of advice: PD and Frame PD

I recently helped my parents order their glasses online and realized that it is very confusing for people not familiar with frame measurements to make educated choices about eyewear online. Especially with some of the cheapest eyewear websites not included in this review, a majority of the new, trendy styles come with very large lenses or over-sized nose bridges (this also applies to "alternative fit" styles coming from Asia). Virtual try-ons often resize the frame to fit your face, so you would never know its real size without reading the numbers.

I have thus far only had a chance to mention this key point in passing. In previous parts of this review, I have talked about lens types, coatings, product guarantees, shipping, costs, quality control and why it costs so much more and is much more difficult to get decent high index lenses compared to standard plastic CR-39 or mid-index polycarbonate (which are not suitable for prescriptions above +/-4.00). I also advised that consumers shop around – online and offline – to find frames in a suitable style, shape and size before attempting to buy the exact or similar frame online. But this is not always possible to do given the constraints and pressures of shopping in-store.

The three retailers chosen herein were selected for their in-home try-on programs, but there are also many other online opticians with even cheaper prices that might offer suitable options within your price range. For instance, Zenni Optical, Eyebuydirect,, 39dollarglasses and Firmoo all offer reasonably cheap frames and lenses. The sites have mixed reviews and their return policies vary from generous to miserly. A full review is outside the scope of this post. Since high-index lenses are never included in the super cheap offers (like “full pair of glasses for $6.95”, “first pair free” or “free lenses”), you have to click through to your cart and choose your lens options before determining your final price. In this way, it's a bit like the bait-and-switch that happens at your optician’s office (Buy-1-get-1-free on all glasses! *single vision, under +/-4.00). It can be daunting and confusing to buy glasses online site unseen, but ultimately cheaper than the companies reviewed in full here. I chose not to take the risk of buying frames that I could not try on beforehand, but I might do so in the future. If you are buying high-index glasses online with or without in-home trials, the following information may be useful.

What is "Frame PD" and why does it matter?

In the previous installments of this multipart review, I made reference numerous times to PD or pupil distance and also to what is known as a "frame PD". These important measurements are what I refer to when I say that a frame is "too big" for my face and/or my prescription. I am spending a bit of time on this because this is a how-to for high index glasses, which require thinned lenses that are prone to aberrations and distortions when incorrectly fitted. If you do not wear high index glasses, this will likely be less of a concern to you, but not irrelevant.

Your Binocular PD or Pupil Distance is the measurement – in millimeters – of the distance between your two pupils. The measurement is needed to prepare your glasses, because it indicates to your optician where your eyes will sit in the frame. This is vital, because when glasses lenses are cut, the center of the lens is the most accurate point of your prescription where your vision will be the clearest. It is also the narrowest point. Distance lenses will flare outwards from there, becoming thicker (and more distorted) towards the edges. Ideally, your eyes should sit centrally in your frames for this reason. The center of the lens (its thinnest point) must sit right in front of your pupil. A millimeter either way could cause issues.

One of the keys to buying glasses online is that you need to know your PD. Your optician will likely measure this with a handy machine that you look into for a few seconds. Liberating this measurement from your optician is no small feat. But, once armed with your PD and your Rx, you are comfortably able to have your glasses made anywhere – including by online retailers at a fraction of the price. Many opticians see giving this number away as bad business. I see not giving it to me as even worse business, because I'll never be back again, not even for an eye exam or when I have comprehensive vision coverage. Luckily I found a helpful optician nearby (after several attempts at different ones) who measured it for me without question. He realized that a) it wasn't taking business away from him because I had no intention of shopping in-store anyway, because b) there was nothing he could do to help me afford his prices. Your local optician may or may not feel the same way. I have heard that Walmart opticians give out PDs to anyone who asks, so that might be the best route if the Walmarts near you are less hideous than the ones in New York.

It is also possible to measure it yourself, using instructions like these. There are now apps for phones and tablets that purport to measure it for you. I'm not going to advertise those here since I can't verify if any of them work. I also doubt the ability of high-index lens wearers to successfully navigate one of these apps once they take their glasses off. If you choose to do it yourself, try it a few times and using the different methods so that you can be sure of its accuracy. Adult PDs are usually between 60 and 66mm and will not change, so you do not have to have it re-measured with every new eye examination.

So, figuring out your personal PD is relatively simple. But what is a "frame PD" and why does it matter? Referring to the measurement sample image from (above), the frame PD is the measurement that includes the lens width plus the bridge distance (nose). So using the figures in the sample, the frame PD is 52mm+18mm, or 70mm.

For illustration, let us assume that your personal binocular PD is 60mm. That leaves a 10mm difference between the two measurements (70mm - 60mm = 10mm). Divide by two and you get 5mm per lens. You can plug the data from your frame into this simple formula to work it out for yourself:

((Frame PD) – (Binocular PD)) = horizontal decentration per lens

The resulting number gives your lens dispenser the appropriate level of "horizontal decentration", or the distance in millimeters that they have to literally slide your lens to one side in your frame so that the thinnest and strongest part of the lens – the center - falls in front of your pupil.

All raw, uncut lenses are large circles (see image above). The lenses in a pair of glasses are smaller, usually oblong and cut out from the blank lens circle. The more off-center they are (based on the horizontal decentration between your PD and the frame PD), the thicker the visible edge will be on your actual glasses. You can see photographs of the process of cutting, centering and glazing lenses here.

Shifting a lens 5mm might not sound a lot, but it is a lot for high indexes. What does it mean for your glasses? Well, the more out-sized your glasses are, the thicker your lenses are going to be. This has aesthetic ramifications, especially for thin metal frames, because your lens edges will stick out of your frame and look like coke bottles. Using my measurements and prescription, if I choose a frame with 54mm lenses and 18mm bridge, my lens edge would be 7.4mm thick at 1.67 high index. By choosing a smaller frame (50x16, for instance), the edge thickness drops to 5.7mm. That is a substantial savings in excess weight and distortion.

If the edges of the lenses are polished, then you will be burdened by glare unless the frame covers it entirely. You will also notice more distortion or warping as you look through the outer areas of the lens (my digital lenses from DB Vision noticeably reduce this). Finally, bigger lenses will be heavier on your nose and can weigh down your glasses, causing them to slide or even give you headaches. A bridge that's too wide for your face will add to your frame's PD and also be prone to sliding. This is an important tip for petite women who want to wear trendy hipster glasses with big lenses, or, like myself, who prefer the fit of men's frames to narrow girly ones.

A helpful tool for determining just how distorted your high index lenses will be depending on the size of the frame and your lens index (1.67 vs. 1.74, for instance) can be found here: Lens Thickness Calculator.

Use a ruler or tape measure against the edge of your current glasses to get an idea of any changes in your Rx affecting the thickness. If you're worried that your lenses will be too thick, the best way to fix that is to choose a frame with a smaller lens width or frame PD. Choosing a thinner lens option will also help, but all the websites that I reviewed here only offered 1.67 high index (except for the special replacement I was given by at 1.74). Acetate frames hide the lens edge more than thin metal frames; thick stems hide it more than narrow ones. Avoid semi-rim styles. But those are mostly superficial concerns. The main reason to avoid over-sized glasses is the eyestrain and potential impact on your visual acuity. That doesn't mean you can't wear wayfarers; they just have to be the right proportion.

The good news is that once you find a pair of glasses that fit your face well and are the right size, you probably won't have to go through this process again. Simply write down the measurements of your frames (they're written on the frame itself) the next time you need to go shopping. If you figure these measurements out at your local optician, you can then freely order on one of the cheaper websites that doesn't offer IHTO and reduce (though not eliminate) your risk of being unhappy with your purchase. As it happens, back before online shopping, I never paid much attention to this and just relied on other people telling me that the frames looked okay. I would get them home later with my prescription in them and usually not be fully happy with the choice. So for me I had to do this from scratch so that I could update my glasses with more modern styles and still get a good fit for my lenses. It was worth the time.

When one optician kept harping on about size, I felt very limited in his showroom. Every time I chose a frame, he would shake his head disapprovingly. He kept insisting on a small, round, wired frame like the one I was desperate to get rid of. And he was right to keep me alerted to size, but buying online (risk-free with free returns) let me experiment a bit more. I now have 3 pairs of glasses all with slightly different sizes, but with a total width (both lenses plus bridge) of either 116 or 117mm. (I didn't measure them at the time, but this is how it worked out, attesting to the fact that you can tell the right frame PD by the fit and how they look on you). They are all different materials and lens heights, from 26mm to 32mm. On the advice of the offline optician, I never would have gone with a 32mm tall lens, but they actually excellent for the range of vision they provide. In short, even high index wearers can experiment – within reason – with frame size and style. Just be sure to shop for your face shape and be aware of potential distortions. I keep linking to this poor girl, but her experience is one we can all learn from: this is what happens when you bargain hunt in haste without checking your ideal measurements!

The End

I have thus far had over 2,000 unique views on this series of posts, attesting to a lot of people seeking information about buying glasses online. I would not hesitate to recommend any cheap glasses website for people buying single vision, regular index glasses, because you can get them as cheaply as $6.95 a pair and are not limited by concerns over distortions. But this review is aimed at high-index wearers whose concerns over lens quality and cost are more profound. Popular shopping forums direct people to sites like GlassyEyes for reviews and tips about buying glasses online, but not only is that site rather slow and out of date, it is also not geared towards high-indexes and does not review any of the three sites that I have ordered from. Judging by the positive responses I have received, my reviews fill a niche in the market. Please get in touch if you need any more personalized eyewear advice or if you would like me to do a review of your products.

To my other regular visitors, we will return to our regularly scheduled anthropological programming in my next post!

Thanks for providing such thorough reviews! I've never ordered glasses online before but am not keen to pay $600 or $700 to order through my eye doctor's office. I was disappointed to find when I tried to place an order with Warby Parker that they can't even fill my prescription (I'm -11 in one eye, and they only go to -10). The tips you provide specifically for people with high-index prescriptions are especially useful since I'm still shopping and looking at my other options.

Fran Barone said...

Many thanks for your comment, Shauna. Looking back, I am glad that I took the chance online so I could finally afford new glasses, but there are certainly some measured risks (more so for high indexes). I didn't realize that Warby Parker only goes up to -10, so thanks for letting me know. They are getting the most press and that's probably why I went for them first when I wasn't sure where to start. But there's plenty of competition. I listed the names of additional companies at the end of my latest review for Mezzmer Eyewear (My Mezzmer glasses turned out to be my favorite and most comfortable pair, btw), if that helps with your search: I'm still writing new reviews. If you have any requests for companies I haven't addressed, let me know and I'll see what I can do.

Michael Czeiszperger said...

If someone wants to buy cheap online glasses, Zenni will sell the frame and lens for $13. The problem with Warby Parker is you're getting the same rock-bottom-quality stuff, and just paying $95 for it.

I recently ordered a spare pair of computer glasses just to try out the Warby Parker experience, and compared that against the same prescription $250 glasses from a local shop. The difference in image quality was very noticeable: with the WP lens on I had trouble reading the same size text on the screen, and the edges were blurry too. This is understandable since one of the differences between a cheap lens and a quality lens is sharpness, i.e. the optical quality of the materials.

At least for me, for a pair of glasses I'm going to wear all day, every day, and be productive at work, and extra $150 is a fair price to pay.

Fran Barone said...

Hi Michael,

Thanks for your comment. I got my Warby Parker glasses when they were still a relatively new company, so I can't speak for any quality decline that might have happened since then. Although I'm not that happy with the fit of my frames (and venturing into WP HQ to have them adjusted was a failure - way too crowded and impossible to breathe in there), the lenses are very clear and high quality. They are as good as, if not better than, my $800 optical store glasses. I've worn glasses since I was a kid and have never been happy with my frames because the lenses always cost upwards of $600. At that rate, I had to choose the cheapest frames (they were never "cheap") and could only ever afford one pair of glasses at a time. WP and Zenni are definitely an improvement for me.

I completely understand your philosophy on investing more in an everyday pair of glasses. I would also do the same and recommend that people have one "investment" pair. But I have to clarify the price thing. A pair of computer glasses for me would never cost $250 at a local optician. The cheapest (and ugliest, of course) pair I could find was $400 and that was with a generous discount. With Zenni, glasses in my Rx with 1.67 lenses cost a minimum of $75 for me plus shipping. It's $125 at WP and as low as $99 (I think; it's only $69 for regular index) from Mezzmer who made my favorite pair for me. The reason why I'd choose not to go with Zenni is because their return policy is poor. I've had to return a couple of pairs of glasses I got online for a replacement frame. Anything less than a no-hassle full refund is not worth bothering with. That said, if I could get my glasses for $13, I certainly would. I know people who order tons of glasses from Zenni, but then they have weak prescriptions and are not as dependent on their glasses as I am. High index lenses always cost more, which makes Zenni too big of a risk for me.

Thanks so much for your thorough reviews! I'm looking to get new glasses soon and would rather not spend hundreds of dollars on unsatisfactory frames/lenses. Apologies if you've already mentioned this somewhere and I just missed it, but would you mind sharing a bit about your prescription? My eyes are in the -7 to -8 range and I'm wondering whether 1.67 high-index lenses are enough, or whether I should go up to 1.74.

Fran Barone said...

Hi dainao. Many thanks for your kind comment. My prescription is pretty much the same as yours. I was concerned about the thickness of 1.67 lenses, having previously gone with 1.74. As far as clarity of vision, the 1.67 are fine; it's just a matter of weight and thickness, IMO. In fact they probably have less distortion. For me, the choice depends on the frame. If you have a an acetate/plastic frame, it will be able to hold the 1.67 lens well, typically covering the edge of the lens so that they don't appear so thick from the side (aesthetically). But if you choose a thin, metal/titanium frame or half-frame, the lens will stick out. In this case, 1.74s are probably necessary to fit within the frame securely and look okay. Frame fit will also be important. Since high index lenses are heavier than the plastic lenses that people with lower prescriptions can get, if the frame is too loose, it will slide down your nose because of the weight of the lenses. I thought it would take me a while to get used to the extra weight of 1.67 glasses since I always wore 1.74, but it hasn't been an issue. I hope this helps!

Cathy said...

Thank you so much for this review! Very helpful! I wanted to get some plastic frames when I went to my last eye doc appt and the girl kept shooting down all the pairs I liked and ending up talking me into a pair that were too big for my face. They looked ok the 3 minutes I wore them at the office, but once I paid $400 for them and got them home, I hated them. Too big and too dark. Luckily, they let me return them and I got a cheaper pair of wire frames, but I still had to pay just as much once you add the lenses. And I still don't have plastic frames!
I started looking at Warby Parker and have done the In Home Try On and found a frame I like but still wasn't sure if I would get a good pair of glasses or not. I usually wear contacts, so my glasses are mostly for evening before bed, so I am hoping the WP's will be ok since they are not going to be worn all the time. I too have a higher prescription (-4 and -5) so your review was VERY informative and has helped me to make a decision to go ahead and get them with the high index lenses. And your info on frame sizes helped greatly. Hoping I have good luck with the WP's but even if they turn out to be not so great glasses, at least I will have a second pair for every so often that didn't cost a fortune.
FYI- I went to the eye doc to pick up my prescription and when asked why I told them I found a pair online and the girl says, "well, good luck with THAT."

Unknown said...

Thanks so much for this exhaustive review. Given my strong prescription I've always been pressured (bullied?) into using brick & mortar opticians, but after spending comically large sums on a parade of unwearable and sometimes unreturnable glasses, often served with a heap of condescension and/or indignation, it's clearly time to switch gears. The obvious labor you've put into this tome has me seriously optimistic for the first time in decades.

Fran Barone said...

Hi Mark Z,

Thanks so much for your comment. I'm actually in the process of moving these reviews to a standalone blog (I didn't realize at the time that I would end up reviewing online glasses so exhaustively). I just got my new Rx, too, so maybe some additional reviews to come. I definitely learned a lot in the process, and the number one thing was not being afraid to say "no" to bad service. Looking back at it now, it wasn't always smooth sailing buying online, but I felt that even with if I had to do a return, the process was preferable to being rushed and bullied in a store. And no one was trying to trick me into believing the materials (frames or lenses) were worth 10xs their actual value. Glasses are so important! Do let me know if you have any questions or requests for reviews and I'll see if I can help.
