For info Reactolite Rapide was the trade name of photochromic glass
lenses produced by Chance-Pilkington, unfortunately no longer in
production.
Corning glass Photobrown/Photgrey glass lenses are still available on
the UK market Go to your local optician and tell them it is in the
Norville catalogue if they argue! They also supply Drivewear lenses
to the profession. Please note any photochromic lens will not work as
well inside a car compared to outside.

A newer version of Transistions will be available on the UK market
towards the end of the year we have been informed.

Gentlemen, I have done some more research and have come up with
Drivewear.Seems to do the job, but no use at night!

Glass photochromics are activated by a combination of visible and UV light.
Light transmission when behind a windshield will be about 50% in full sun, less
when cloudy.

Corning developed the technology, reactolite is probably the trade name used in
the UK. Also known as Photogrey/brown. Thin & Dark is an improved version,
available in grey only.

The big boxes won't have them. Try the independent doctors and opticians.

Thanks guys. I have got used to the idea of 1 pair of glasses that
does everything. It just damn annoys me that I cannot do that any
longer!!

I used to use polarised clip on years ago, but found that reacolite
just did it for me.
Robert, do you know of any branded photochromic that changes in the
car?

I am actually in the UK, where every thing seems to be transitions. I
have tried 4 opticians from large high street to back street. All the
same!!

Try a different optician. Ask for glass photochromics. Readily available
worldwide in a variety of lens designs.

You could have both- keep the clips in the car and use the
photochromatics/transitions for convenience. Sample both the brown and the grey.
I'm using brown more than 90% of the time.

John's right- once you wear the polarized lens you won't go back, if you can
tolerate taking them on and off and carrying them with you when you go out.
Probably a big "if" from the sounds of it. Demo the polarized lens just to be
sure.

I don't know anything about this "Reactolite" brand, but my solution
for driving is to use magnetic clip-ons. You can grab them with just
one hand and pop them right on, because they stick using magnets. The
nice thing about them is that they are polarized. It makes a real
difference. You will never want to go back to your reactolites once
you use a polarized lens for driving.

People, I have a problem, which hopefully someone can help with!
I have worn glasses for over 50 years, and have only ever needed /
wanted 1 pair of spectacles. For over 20 years I have used Reactolite
Rapide lenses which do everything I want.

They are now no longer available, so my optician has supplied
Transitions which I think are crap.
They are clearv indoors, and not very dark outside, but the worst
thing for me is they do not work in the car.
I spend alot of time in bright sunshine, driving and out of the car,
and cannot cope with changing glasses all the time.

Someone must do a photochromic lens that works in the car. Reactolites
did!!
