This is one of the most useful threads here ever. I have followed it with interest.

I was thinking about this while driving home the other night. Would wearing glasses with an anti-reflective coating help with night driving even if your vision was perfect?

If your vision is perfect, so you don't normally wear glasses, then I can't believe lenses with AR coating would be as good as "no lenses at all."

AR coatings (as I understand it anyway) are intended to reduce the reflections you get from lenses. I'm not sure if they're primarily intended to reduce surface reflections (e.g. seeing a reflection of something behind you in the corner of your eye) or internal reflections (light bouncing between front & back surfaces), but I think it's the latter. Some lenses (especially high-index plastics) have a lot of internal reflections that can produce a foggy or "halo" effect. I think that's what AR coatings are intended to reduce. Though I have to confess I've never understood how a coating on the OUTside of the lens can affect reflections from the INside surfaces...

I blame Craig Rounds!! Shocked

For making me buy these cheap eyebuydirect glasses. Razz

I guess I have owned these three pair of glasses for three months. In that time, I have had four nose pads (?) break off. In all my years of owning sunglasses, I have never had them break off. Is this normal or unusual?

Anyway, Craig said Zenni is offering an anti-reflective coating on their glasses now and in his opinion the frames are better (at least in the ones he has sampled). I am going to try zenni and see how they hold up.

So I just wanted to write back that the customer service at EyeBuyDirect is pretty good, but I have not had a good experience with the quality of their frames.

I first made an order for two pair of glasses; one was for the "Clem" style frame ($47) and the other was the "Achinsk" style frame ($39). When the glasses arrived, both pair were out-gassing and had a terrible smell that lasted for about a week. The Clem glasses looked absolutely ridiculous on me so I decided to send them back under their replacement policy.

As a replacement I ordered the "Vernon XL" ($52). This cost me about $15 because I had to pay shipping to receive the new glasses and to send the ugly ones back. I like the look of the "Vernon XL" on me, but when I went to adjust the nose piece on the bridge the part of the bridge that holds the nose piece snapped right off. I have had rimless glasses for years and have adjusted them myself many many times and I have never broken a frame before.

I sent EBD an email about the broken frame and they told me that I could have another pair for 50% off and I would have to pay shipping again for both directions for another $15 or so. I called them on the phone and they agreed to send me another pair for only shipping costs. So first they wanted to charge me 50% to replace a defective or low quality frame, but then they agreed not to charge for the hardware, but I am still out the shipping charges and am not thrilled with being asked to pay 50% to cover poorly made glasses from EBD.

At this point I don't know if I will by from EBD again or not. ZenniOptical frames seem to be of much higher quality than what I have gotten from EBD. All three of the EBD frames smell(ed) terrible while they are out-gassing and I have never had this with Zenni. Also, the frames from EBD are adjusted very weird when they arrive and require massive adjustments to get them on your face the first time. ZenniOptical glasses usually fit on me pretty well right out of the box with little adjustments (like seriously EBD adjustments for the frames would fit on some alien species out of the box, but not humans).

Something weird about all three EBD pair of glasses is also that they all sit very high on my face. The top of the lenses are well above my brows and the bottoms are bothersome because they are too high and I can see them even while looking straight ahead. Again, I have never had this with ZenniOptical and this is only true with the EBD frames.

So maybe it's just me and the EBD frames will fit others better, but I have definitely had much better results from ZenniOptical.

That sucks, Craig. I haven't really noticed any issues with fit regarding my glasses, but admittedly my frame of reference is limited to these glasses and sunglasses. I didn't notice any outgassing smell either. It did take them three weeks to get here, so maybe they were fine by then.

My biggest issue is the plastic nose pieces broke off. I have never had that happen with sunglasses before. Of course the only glasses I wear a lot are my reading glasses. I only wear my regular glasses at night while driving.

I would like to try Zenni, but I have a real issue with UV coatings. On my regular glasses, I can see the light yellow tint that my reading glasses don't have. I was looking at the reading glasses that my eye doctor sold me and the yellow tint is even worse on them. When I am working, I can't have this color distortion. I already had a nightmare weekend with a customer who kept telling me the color was off even though it was so close no one but him or I could tell the difference. I understand the value of the UV coating, but it isn't needed indoors. I wonder if Zenni would leave the UV coating off on a special order.

Spanky, can you tolerate the high-index plastics? Those are the ones that they generally push, since they're lighter, thinner, and oh coincidentally more expensive. Craig and I can't tolerate them because of our high prescriptions. But if you can, most of those plastics have inherent UV blocking. They shouldn't need any UV coating at all.

From what I read, CR39 has about SPF4. More is better, so coatings on CR39 are a good idea, especially if you spend a lot of time in the sun. For Trivex, polycarbonate, etc, they have basically 100% UV protection as a property of the plastic. UV coatings are not necessary.

I could probably tolerate the higher index, but I am satisfied with the regular lenses. The only glasses that I need to have UV coating on them are my sunglasses.
