Clip-ons have come a long way! They actually come as a set in some cases and match your glasses perfectly. Some literally clip on and others use magnets. I loved mine till I lost them, but that was completely my fault. <shrug>

Better control because you determine when you're wearing sunglasses and when you're not. You have absolutely no control over your Transitions lenses - they get dark when uv light hits them, and light when it doesn't. When you walk from bright daylight into a dimly lit restaurant, the lenses will take 7-10 minutes to fade. In essence, they're sunglasses for awhile when you don't want them to be sunglasses. With over-rx or clip-ons, you don't have to take off your clear Rx glasses - they both go on top of your clear glasses, and the change is immediate.

The most convenient are the magnetic clip-on sunglasses, but they're not inexpensive.

I've seen it a couple of times. It's disappointing when I have to tell someone that the frame they bought on line doesn't fit them or is incompatible with their Rx.

but I'd still be clipping them on and off constantly, if I'm running errands and stuff.

I don't have a real problem with the Transitions staying too dark when I come in.

Not arguing, just debating, since I have an imminent glasses purchase to make.

Also, do you know --- I'm not sure what coatings my present glasses have, but I noticed after a while that I've got some iridescence on them. Is that the anti-reflective coating? Does it just do that, or maybe I messed it up by washing with soap and water?

Its not that big a deal to do/undo the clip-ons.

Personally, I will NEVER buy that anti-reflective crap EVAHHHHHHHHHH again.

My friend and cow order just showed me her scratched glasses -- from using clip ons

That's another reason I don't want real glasses. I'm hell on glasses. I had a prescription pair (paid for by an old job) that had scratch resistant crap. That shit didn't resist anything.

Magic Clips are teh sweeetness. When you paid tha cost to be tha boss you will wear these and then you will know, my droogs.

Yep, that's AR
I never go without it.
I'll bet they're the kind that clamp onto the lens. Magnetic clip-ons are held away from the lenses.
I don't know what you had, but I was around before scratch resistant coatings. Now THAT was bad!
You're as clear as an unmuddy lake. As clear as an azure sky of deepest summer. Time for a little of the Ludwig Van.

As a photographer I am vision obsessed. As far as I'm concerned there cannot be enough AR coatings on my glasses. I want my glassses to have the same shit that's on my lenses.
I fucking hate flare.

That's how mmhnmlmmhmnsmmn would spell it!

@Flint
I thought you said you wanted to be part of the team.

I have a pair of Magic Clips and one of the arms recently broke off right at the frame. Otherwise the glasses are in perfect condition. I don't want to buy a whole new set of frames/lenses/sunglasses, but I haven't been able to get them fixed. I don't remember how much they cost, but I know it was a lot.

Get the Bendium ones that don't break:

Do they make these in prescription?
