A guy I work for has the glasses that shift in different light. It looks like it takes less than a minute to get to the "inside" light when he comes in from the parking lot on a sunny day. A minute -could- be too long, especially if you're entering a crowded area. But he loves them. My dad used to have photo-greys, they didn't get as dark as he wanted them to outside but most of the time they were sufficient.

Those are fine if you don't have any serious eye problems - if all you are correcting is refraction. But, when such things as cataracts, glaucoma, others that I can't name, then real sun glasses become more important. I'm using the term "real" rather loosely. Don't know exactly how to distinguish but you don't want the glare of sunlight on cataracts, for example, ever.
Transitions lenses do work reducing flare. They also Block 100% of UVA & UVB rays, and turn very dark within a few seconds. I have been wearing eyeglasses with Transitions lenses for numerous years, and they work as follows: when you step outside the lenses adjust to the amount of daylight. The more light there is, the darker they get. It means that under the sun they will turn as dark or darker than sunglasses. Then when you step inside the house where is darker, the lenses change from dark to clear in a matter of seconds.
That said, if you are taking photos in the middle of the day (lost of daylight), as you look through the viewfinder of your camera the lenses make it difficult to see the camera's settings displayed in the viewfinder, much like when wearing sunglasses. Also, since automobile windshields and windows block UV and UVB light, the Transitions lenses won't turn dark when you are inside the car and the windows are raised.
I have both prescription sunglasses and eyeglasses with Transitions lenses, and wear the sunglasses when I want to have a larger area of shade over my eyes. The sunglasses are much larger than my regular eyeglasses, and cover my eyes out toward my temples. When you go to an optical shop, ask if they offer prescription sunglasses, too. At the local Sam's Club's optical shop, they offered me regular eyeglasses with Transitions, and a set of prescription sunglasses for half the price. I got both, of course.
I have several types of glasses.
One (regular, daily wear) pair is coated with a protective coating (crizal or something similar) that not only reduces/prevents scratches, but also reduces glare dramatically compared to untreated lenses. I also have the type of glasses that darken when outdoors...those work well when I don't want to change glasses. These too are coated with the other 'stuff' so very limited if any glare. And, finally, my prescription polarized sunglasses are very dark, and work extremely well..even in a pool, or on a boat, etc. They work so well I cannot read my I-phone in some cases. I rarely experience glare with these three glasses. The glasses I own that have the clip on sunglasses however are not equivalent and I experience more 'glare' issues - but I like the convenience. Each pair works in different situations.
I have a print-out about sunglasses written by Dennis Robertson, M.D.. One paragraph is as follows:
"Standard prescription eyeglasses in the U.S. are treated to provide UV protection while retaining a clear, nontinted appearance. Some contact lenses also offer UV protection, but should be worn in combination with sunglasses to maximize protection."
I am wondering it this means all prescription eyeglasses in the U.S. are invariably so treated without having to ask for it. Or, does it mean that in the U.S. this is available upon request?
I like the flip-ups best of all but they are not made in good polaroid plus U.V. protection glasses. They are just a thin piece of plastic with some polaroid but have no U.V. protection so far as I know. I've asked many places and that is what I've always been told. My eye doctor told me that they are fine for a fast trip outside and back in but not for a long exposure. Oh well, for only $10, what can we expect?
Flip-ups surely come in handy, though, when you have to go into a shop and then step back outside.
I see no section for eye care. So, shall just steal a corner here. I was told something this morning that I'd like to confirm if anyone else has had the experience. I'd mentioned to the young woman at the cash register in the drug store that sun glasses were totally useless when the sun is directly in my face. She agreed and said that's why she never wears them. However, she had a story to tell along with that. She says her mother did this and has had no more problems with sun glasses causing glare.
If you wear prescription glasses, you take the sun glasses to your optometrist and ask her to put the prescription in the sun glasses. That, she said, solves the problem. Her mother is a happy camper with her prescription sun glasses.
Has anyone else heard of this or know anyone who has done it? The sun glasses alone cost me a small fortune. I don't want to spend more getting the Rx put into them if it isn't going to work and I have to then buy new glasses.
Thank you.
You will have to buy new lenses because they must be made to order with the prescription.
They used to have these stick on magnifying things that you could put on glasses or sunglasses that would make them into reading glasses. But as far as a full prescription, you have to have the lenses made to order.

I have been wearing Transitions since they first came out and I do not wear anything else. I have the gray tinting. I find that more powerful than the brown tint. When I'm out in full sun, they look black if you look at me but from behind the lenses everything looks "normal". They also change very quickly if I go into a more dark environment. Driving in the car they turn as much as they need to. I had a pair of Polaroid sunglasses once but didn't like them.
Maui Jim sunglasses owns the patent on a lens technology that wipes out 99.9% of glare and blocks 100% of harmful UV. They have a proprietary lens layering with "rare earth elements" that also boosts color to brighten viewing.
You can get them with an Rx, too: Maui Jim RX
But, they will cost you! I have had mine for years. They are excellent with replacements, if you break them, too.

Hi my old Fringe buddy!
Yes, I prefer the gray tint as well.
