Does it really matter? If they help you see better, get them.

Transitions? As in the ones that go darker in the sun? My husband has had them forever. Easier than keeping a separate pair of prescription sunglasses around I guess. We’re 42 now but I’m pretty sure he had them when we met at 25.

I'm 41, I don't have transitions but both of my kids, 20 & 14 have them.

My ten year old niece had them, twenty years ago.

Even then they had improved tremendously.

No.

I have had transitions lenses since my 20s. I am fairly light sensitive and they really make things more pleasant without having to switch to prescription sunglasses.

I switched to contacts and had to carry sunglasses all the time, until the transitions contacts came out. Those things are awesome and make colors so much better when they tint. They aren't as good as sunglasses, but still do great.

Not really, but you see them a bit more often with old people, because the lenses inside the eyes become less flexible with age.

However, an alternative can be contacts with reading glasses. Can be frustrating to pop out the glasses often. Probably not good for driving idk

My wife had them in her twenties about 10 years ago, she couldn't get on with them because of how slow they returned to normal after going indoors.

I've never heard of them being for old people.

Transition lenses are the ones where you have reading lenses in the bottom and long distance lenses at the top? I guess they are for anyone who suffers both from myopia and hyperopia. Although you could just get contacts and a pair of reading glasses.
