Ultrasonic cleaners, with a bit of dishes soap in the water, are the most efficient/effective way (I uses to clean them with water and soap as well, in the past). They are simple devices that lightly shake objects very quickly, in water. They work well with dirt that is soft (e.g. grease), and therefore not only for glasses, but also for teeth aligners and jewelry/small objects. Some grease is still sticky, but gener…

What uncoated lenses do you have? Polycarbonate lenses usually have an anti-scratch coating, and most lenses have an AR coating as well.

I think the intention was (cheap (coated lenses esp. sunglasses)) though they wrote it as (coated lenses (esp. cheap sunglasses)).

I have a few uncoated lenses, such as semi-disposable safety goggles, and a few uncoated glass lenses of one sort or another, although I expect you didn't mean those.

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. For some stubborn things (like sunscreen) in the edges I sometimes gently use a Q-tip. 4. Rinse under warm water. Gently rub with your fingers to agitate the soapy water and help rinse it off. 5. (This is the important step) Adjust the faucet’s flow to a low lam…

I do some optics design and prototyping for my day job. This is close enough to how I clean expensive optics, except that I would avoid a q tip unless absolutely necessary. The only thing I'd add is if you do need to dry something with a cloth, an old cotton undershirt that's been washed many times does a great job.

Also, I wash my windows at home with plain water and a squeegee.

Wash with cold water. Warm or hot water might ruin the coating. This is why I worry about radiant heat from fires while camping or burning yard debris. Plastic lenses are usually opaque to IR and that means they're heating up even more than you might think.

I once ruined the coating of my glasses by sticking my head into a hot oven to check a disk I was baking. The surface of the lens sort of blistered. From then on I removed my glasses when checking on food in the oven... I also try not to stick my head so far in also.

Chef tip: Take the item out of the oven instead of inserting your head into the oven.

I asked my optician to please give me glass lenses and avoid the shenanigans with inferior materials, but they declined citing safety concerns with broken glass. Ah well.

Glass lenses are only good for spherical prescriptions. If you have astigmatism, you need an aspherical lens, which cannot be shaped in glass.

I've owned several pairs of aspherical lenses made of glass, ground by competent yet hardly exceptional shops. Only in the U.S. I found people uninterested in selling me glass lenses--exaggerated mimicry, "but they'll be so heavy!", etc.

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…

Glasses are plastic lenses? I thought they were… glass. Am I wrong? Warby Parker and such are plastic?

Can you even get glass lenses anymore? I don’t recall seeing it as an option the last time I ordered a pair but maybe since Zenni tends to focus on affordability they don’t bother offering the (presumably more expensive) option.

Yes https://lensfactory.com/ They are so much better.

Do they shatter when you drop them?

This is exactly what I do.

I know someone that cleaned their hard contacts like this too.

They used to be actually glass, but now the majority are plastic.

Glass lenses are only good for spherical prescriptions. If you have astigmatism, you need an aspherical lens, which cannot be shaped in glass.

Anyone who is into photography knows this is flat-out untrue. Aspherical lenses are a big deal in the high-end camera lens world. Canon, Nikon, Leica, Zeiss, etc. all have aspherical lenses.

I wear glasses and my glass lenses are made by Zeiss. My left eye has mild astigmatism and the glasses correct it perfectly. Each one is made from a single piece of glass that is ground to shape.
