Thats not true, I have glass aspherical lens.

That you wear for prescription glasses? Unlikely. Glass cannot be shaped into aspheres without very expensive grinding and polishing techniques. Multiple glass shapes are typically molded together to make an aspheric lens. The challenge is that molding the lens this way decreases the Abbe number significantly, which is why it’s not used for prescription eye glasses. If you have astigmatism, your lenses are most likel…

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.

Avoid moisturizing soap in general when doing this, since they often have silicones, and that can leave a film. Dish soaps are less likely to have them, so it's a decent one to try blindly... or just read the label.

But yep, this is exactly what I do. Usually hand soap, but the stuff I get is just plain soap, no fragrance or moisturizer, so it rinses super easily. And when it's properly clean, the water leaves the surface dry and streak-free.

This is what I do, usually once or twice a day. I seem to touch my face and glasses a lot, so dish soap is important as it removes the grease. Hand soap isn't as powerful and often has additives that will leave a film behind.

Between cleanings when I get a small smudge I go back to using my t-shirt, but I only clean the specific area that is dirty.

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 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.

Fun fact: if you're ever institutionalized for suicide watch, they confiscate your spectacles due to a perceived risk of being able to break them and cut yourself, even if your spectacles aren't made of glass.

I got LASIK. One of the best decisions I have ever made. EDIT TO ADD: I got the surgery 3 years ago, I'm 42 now. Post surgery I am at 20/15 vision. No complications, and no side effects. If anyone is interested, here is the video of the entire procedure (they even offered to live stream it on facebook for me): https://www.youtube.com/watch?v=P4YOuS-nznk

Please tell us more. How old are you, how long ago was the surgery, how is your vision now, any side effects?

Sure thing. I edited my original comment.

Are optical coatings that sensitive that warm water might bother them? I'll have to treat my lenses differently.

Yeah, I used to wash my glasses in hot water. I didn't notice an instant change, but it noticably degraded their quality after a while. Water straight from your cold tap is the way to go.

That sounds about right. I remember having gone to an optometrists office some time back and they were able to cut lenses right there and have glasses ready in an hour. I was amazed and couldn't understand why everyone couldn't do this. Sunglasses are the worst. They cost basically nothing to make but the profit margin is Inf% b/c of branding. A $20 (at most) pair of non-name sunglasses instantly becomes a $700 pair…

The locally made lenses still exists but it's becoming very rare. When I was a kid my parents went to a one-hour place, that made them on the spot. It's still possible but not economical. Not that they passed the savings to the consumer of course. Gotta love economies of scale. If forgot to mention sales commissions as I was talking about cost of goods. But a variable compensation for the sales person, is a lot of yo…

That makes a ton of sense and explains why opticians are paid so low (relative to other medical fields).

I use a tall glass with tap water and some dish soap. Dunk them in while I shower, then remove, rinse off with cold water. Afterwards I could use a towel, but actually I tap them dry with a sheet of toilet paper. I THOUGHT that would leave small dust, but surprisingly, does not.

I use cheap, uncoated glasses though and replace them every 3-4 years anyways.

There's absolutely nothing unsafe about glass lenses if you're a normal person and don't abuse them. They're actually superior to plastic in terms of longevity and durability. What I've found is that the tradeoff is durability vs. weight. Glass is heavier than plastic but if your glasses are well-fitted and adjusted, this is not a problem. Also, in terms of cleaning you can be a lot less careful with glass and they w…

I have glass lenses, but I don't care to find out what happens if ever an airbag explodes into my face.

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

Do they shatter when you drop them?

They might if you drop them hard enough, but I've dropped glass lenses numerous times and I've never had them shatter on me. Probably helps to have a sturdy frame with barrel hinges, too: https://shop.shuron.com/shop/sidewinder/
