The best method I’ve found so far: 1. Get your glasses wet with warm water. 2. Apply dish soap to both lenses. 3. Gently rub the soapy water over the lenses.

> 5. (This is the important step) Adjust the faucet’s flow to a low laminar flow and run the glasses through water, hitting the top of the glasses first and letting the water flow down and off the bottom of the lenses. It might take a couple passes but doing this will eliminate any water droplets on the lenses. This final step is also how soldiers get those perfect mirror finishes on their boots and belts!

I did it by using lots of polish, time, and a little (drops of) water. I don't remember holding my boots under a faucet, maybe I could have had an easier time if I'd have known back then. Some folks did use heat guns, but that always made the polish crack for me.

After you’ve water-bulled with the little drops of water how did you get the water off without leaving any streaks? This laminar flow approach collects them up and rolls them off as larger drops so the surface is left dry.

I bought a device with some kind of cloth pads held opposite each other, and when you close it they brush up against an inner pad which presumably removes grease from them.

It cost £20 and I was dubious about it, but it cleans better than I've ever managed by myself with a spray. Lasted about 1.5y before it stopped being effective (just moves grease around rather than picking it up) and I went and bought another one.

Who has this kind of time? I've been wearing glasses since I was a kid too and my approach is: don't worry about it, clean them if things look bad.

Unless this is maybe parody and I failed to pick up on that?

Absolutely first thing to do is hold the glasses under the faucet to get dust particles off.

Follow with, as others have said, dish soap, fingers and microfiber.

You can get water shedding coatings for lenses. Then you just have a few beads of water when you do this. You can either leave them there to dry or dab at them with a soft cloth like a tee-shirt.

Since I've started doing this I've actually had compliments from optometrists what good shape my lenses are in.

I asked the optician how they clean glasses: - Wash with cold water. Warm or hot water might ruin the coating. (Our water comes supercooled right out of the tap in the winter,so in order to not have my hands instantly frozen into a solid block of ice I go for 15—20 degrees or so.) - Use a drop of mild dish soap without ammonia. - Dry them with a soft clean cloth (they use microfiber I think, I just use a random soft…

I second this. Super easy to do and kept my current 1 year old glasses in great shape.

I just lick the lens and rub with a cloth. Spit and shine.

Ain't no way I could brush the dust off, it's all glued on by oil. I guess I'm a fat fucker and produce way more oil than normal, though...

Even with Zenni my eyeglasses cost over $100. At Costco they cost $300, and at most other places they cost $600. I used to always go with Costco, but last year I tried Zenni. The frames are definitely flimsier than any others I've had, which I've heard is generally the case for their wire-frame options—I'm sure their heavy plastic frames are more sturdy, but that's not my style. But the lenses seem as good as usual.…

7-8mm thick?! That's insane. I am pretty sure you can get thinner lenses by using a different index. It will be more expensive but definitely worth it. My Rx is -8.5 and my lenses are reasonably thin.

I can definitely get thinner lenses using a higher-index material, but I selected this lens material specifically because it has a higher Abbe number and thus has less chromatic aberrations. The thickness doesn't bother me, but chromatic aberrations do, a lot. I cannot tolerate the excessive colour fringing high-index lenses have, and while contact lenses don't have this problem I dislike those even more.

I have lenses with an optical index of 1.61, which have an Abbe number of 41. In comparison, basic polycarbonate has Abbe 30 (horrible), high-index 1.67 has Abbe 32, and high-index 1.74 has Abbe 33. The best is CR-39 (index 1.5) with Abbe 59, but that will result in an absurdly thick lens, and I'm not sure it's even available in such a strong prescription.
