I wear spectacles for driving and am tired swapping between normal glasses and sunglasses. I feel this is dangerous and thought about getting reactions lenses. I live in the UK and the girl in the opticians said I would be disappointed with them as they react to UV rays- most of which are absorbed by the windscreen so they will never go dark unless you have a sunroof. Also, she says the lenses never go really clear - there is always a slight tint. I want some feedback from people who have reactions lenses and advice on this issue please - thanks.

I have them. There is a slight tint on them most of the time but it's not noticable. They're good for driving (but intense sunlight will still blind you, and they do take a while to change).

She is right, reactions react to u.v rays and the windscreen block these so they don't go as dark as they would being outside. The only thing you can do is stand outside until they're at full darkness and then get into the car. With reactions they start to retain some of their colour over time, its actually worse if the lenses are glass not plastic and they will never go back to being completely clear after some years. Sunglasses are best if you want a really dark tint as reactions will never go as dark as a sunglass lens. The only reaction lens that goes anyway near as dark is a Transitions lens. These are completely clear to start with and go extremely dark in the sunshine. You have to be careful with some tints as well as they can make traffic lights seem different in colour than they are.Believe it or not they actually go darker in cold weather and work better if your on a skiing holiday as there are more uv rays bouncing around as everything is white and bright! I have been in optics for over 15 years.

Both I and my wife wear reactorlight glasses.
And your optician is correct. The lead in the windscreen stops most UV so the glasses don't darken very much.
My wife has a pair of prescription sunglasses But I prefer a large pair of sunglasses that fit over the top of my normal glasses and have a wrap round so that light comming in through the side window is blocked also
There is no quick fix to this problem

I have used these type of glasses for many years, and I would not willing go back to "normal" lenses.
I must confess that they always have a very slight tint not really noticeable to the user, in fact even to some one looking at you.
The speed of the tinting is very dependant on the amount of light they are subjected to, normally with in 40 seconds mine are quite heavily tinted in bright sun light. I do drive and the lenses still react but not as much as being out side but there again when driving you only get light through the wind screen which again has a narrow view of the sky(source of light) but perfectly adequate for me as you normally do not drive directly into the sun.
The speed of change used to be dependent on how much you pay, as well as amount of light, but I do not think so these days.
There seem to be to main colours for the tints one being gray the other being a brown colour.
Again I can only say best thing I did buying these kind of glasses, no doubt some one else my think differently
Regards
John

Personally I'm fed up with the "lag" in reactolite lenses when driving and they don't work terribly well behind a windscreen.
I've now got a cheapo pair of conventional glasses I use for driving, together with a large pair of sunglasses which I can whip on and off over the top of my specs as and when necessary.

lol...My dad has reactions lenses... they go dark in the supermarket under the lights and everyone gives him a funny look...
And this girl in my year at school has them... they're permanently yellow- not a slight tint, but really yellow- even when storm clouds are brewing!
But whats the point? We don't have that good weather... okay... there are 2 really hot months in the summer... but its too hot to do anything then!
My dads go dark in the car (in the sunlight)- although Ordinary car window glass filters out about 97% of the UV-B radiation and about 37% of UV-A radiation, they should still work!
Good luck!

My partner wears reaction lenses. He has no problems with them when driving; they always work.
They don't cost much more than ordinary lenses. I think you will find them much better: and safer than switching frequently!
