Reactive glasses

[ufkacbln]

I'm thinking of getting some reactive glasses. I currently have interchangeable lenses, and it's a bit of a pain carrying the extra lenses and a cleaning cloth, and stopping to change them.
I ride in varying light conditions in the south of France, the light changes between shade and sun can be large.
It's a possibility I will be looking for prescription lenses too, just to make it more difficult. I can see where I'm going, but I can't see the Garmin, which is a frustration. Not sure whether it's worth going to prescription lenses for this.
Advice and experiences would be welcome

I use the Rudy Project RX for this reason

The insert is a varifocal lens that I renew with my prescriptions

I then use the photo-chromatic lenses, mainly the Racing Red, but the darker lenses are used on bright days

Mistake there methinks!

I had some 'transitions' (I think) lenses made for some Oakley frames (normal glasses though, not cycling glasses: I wore them all the time) - they were ok, but at the time I was driving a lot for work, and I hadn't realised they don't work through glass, so were useless in the car. They also take a while to change, as others have said, which can be annoying.

I used to have reacting prescription lens for several years and when I was outside on a sunny day they were great. However, it worth remembering they react to ultra violet light and not sunshine. Hence, even on a dull, cloudy day when you don't need any shading they will darken to some extent. Also, as byegad as indicated they don't react too quickly when the light conditions change. If this isn't enough, when driving the car's windscreen keeps out most of the UV light and so they do not darken even when the sun's glare is hindering your visibility.

The light conditions in the south of France may be more suited to them than here in eastern England but I have gone back to ordinary lenses for general use and will buy some prescribed sunglasses.

I understand the latest lenses can react to visible light, certainly my new lenses darken in the car. My problem is with high contrast conditions, seeing into the shade, tho'

Like @byegad prescription variously reaction lenses, but they're not polarised so I usually end up with clip ons anyway
