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.

- wyclif 4y agoAnother reason to consider glass lenses.
- elliekelly 4y agoCan 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.
- not_the_fda 4y agoYes https://lensfactory.com/ https://lensfactory.com/ They are so much better.
- oAlbe 4y agoDo they shatter when you drop them?
- wyclif 4y agoThey 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/ https://shop.shuron.com/shop/sidewinder/
- Fnoord 4y agoHeh, its funny, whenever I see a video of an American with glasses, they don't have a reflective coating. I guess its too expensive over there. I have glasses which have reflective coating and photochromic coating. They're also made of titanium. Very light, despite being -4 or so. My wife has even worse than -4, and she enjoys the same. They're a tad more expensive, yes, and eventually the coating goes bad which with proper usage can be postponed for years (e.g. wear real sunglasses on beach).
- causi 4y agoUnless they're completely plain lenses the heat could still ruin the oleophobic and anti-reflective coatings.
- Grazester 4y agoI 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.
- willcipriano 4y agoChef tip: Take the item out of the oven instead of inserting your head into the oven.

- hammock 4y agoGlasses are plastic lenses? I thought they were… glass. Am I wrong? Warby Parker and such are plastic?
- userbinator 4y agoThey used to be actually glass, but now the majority are plastic.
- ek750 4y agoFor people with poor eyesight (like me!) plastic lenses are lighter and can have a higher refractive index, making them thinner than the equivalent glass lenses. Weight is the big thing though.
