I want transitions lenses so bad, but the women in my life won’t let me 😔

They work based on UV light. So they will not transition inside cars. They also will not transition in cold weather, so you’ll walk in snow with clear glasses and have dark ones for 5 minutes once you go inside.

Never had them not work in cold. They change even during heavy snowfall when it’s well below freezing and well, no sun, heavy clouds. It’s great because they help with the glare from snow.

I could never get a straight answer. I think it’s fashion.

If it’s the women in your life, then yes. They are the epitome of turbo-dork when it comes to eyewear.

You know, we’re generalising, but you’ve got a point. None of my male friends have glasses in any kinds of shapes other than “boring grey ovoid.”

Why not? I thought they were pretty popular.

I don’t know. I think it’s because they’re practical?

It’s because they are not practical. They do not work inside cars, they transition super slow in winter, they are clear when you need sun glasses and dark when you need to see.

So the scenario is A) you have transitions that work 90% of the time and a pair of prescription sunglasses for the times they don’t Or B) you have regular glasses, and still have prescription sunglasses.
Option a means 90% of the time you don’t need to carry an additional pair of glasses with you.
I used transition lenses for a decade, they are great.

They transition just fine in winter, even down to 10f or lower.
They have a version that works in cars now. But that’s an issue with the car windshield blocking UV. So leave a magnetic “clip on” shades in the car. They look exactly like your frames, with them attached you can’t tell they just stick on from the front - they look just like your glasses.

They worked pretty well when I was in high school marching band. I didn’t drive yet so I didn’t need road vision, they darkened while out at practice and were clear elsewhen. Got an actual pair of prescription sunglasses in flight school though.
