Just an FYI, I had that happen to my driving glasses a couple years back. My optometrist said that because you cannot leave glasses in a hot car as the heat destroys the coating… OK thanks for telling me AFTER the fact, where do you THINK I am keeping a pair of glasses that you designed specifically for my driving vision? And by the way, I’ve been wearing glasses for over 35 years and always had the anti-glare coating for night driving, what did you change that is suddenly making them self-destruct when they are stored where I need them???
Yeah they had no answers for me. But OP, if you left your glasses in your car, that’s probably what happened to the coating.
Just an FYI, temperatures in a car in direct sunlight can exceed 165F. Very quickly.
I know this because I left a glass thermometer under my seat for an hour one summer. When I came back to grab it, the glass has burst (max on the scale was 165F).
I have no idea about lens coating changes over time and their heat tolerance, but the insides of cars can be fucking awful.
Oh I agree it can be a friggin’ furnace. My complaint was that I’d never had that happen before so why is it happening now? And if I can’t keep my driving glasses in my vehicle, where am I supposed to keep them? Maybe keep them at my desk just in case my monitor suddenly gets really far away?
I’m sure that’s the case for a lot of people, however my particular locations has actually been getting more temperate – cooler in the Summer and warmer in the Winter. I mean it’s not by much, but we’re lucky to not be getting these massive heat waves the rest of the country has been seeing.
New coating that is better or cheaper or harder but worse with temperature. Or maybe some new blue light filter. Or the old coating had lead in it or something lol.
I saw a guy on YouTube a few years ago, heat water in the car to temperatures hot enough to brew coffee, which he then went ahead and did. It was a cool video. I doubt I’ll be able to, but I’ll try to find it. Anyway, yeah, cars are super hot in the sun.
Edit: I found it, searching for ‘brew coffee in your car’, so simple haha. Holy crap! 6 years! He hasn’t posted anything in a long time. Hope he’s ok…
Specialists can be so stupid. I think doctors don’t get enough sleep. Somehow they end up extremely disconnected from their customers’ actual needs.
Blows my mind that they wouldn’t think to tell you this. Why wouldn’t they have a checklist of things to cover? Any appliance salesman is going to have a list of things he tells you when you’re packing up a new dryer to take home. Why is that schlub taking his job more seriously than a doctor?
I honestly don’t get it. Part of me suspects the white lab coats interfere with a sense of shared experience. Kinda like the doorway effect, but with clothes.
You’re overthinking this. Company decided to cheap out to raise profits, so they changed the formula for something that will last X years instead of XX years and hoped no one would notice.

That’s 74 degrees Celsius for the rest of the world

Could have something to do with global warming.

TIL what happens when the thermometer maxes out
No but I did take a trip to the deep south, Kentucky is a killer this time of year
You could have gone DEEPER
I mean technically I started in SC, Left before the hurricane, drove up to Illinois, it’s just Kentucky was the hottest spot I found
Ugh I bet.

They don’t have an answer for you because it’s all EssilorLuxottica.
