Hello. FYI I'm a consumer.

I've never tried photochromic lenses before but am considering trying
them for a new prescription. I'm trying to compare the following
plastic lenses:

+ Corning SunSensors
+ Transition III and Quantum
+ Rodenstock ColorMatic

I live in Dallas, TX. I've had prescription sunglasses made in the
past but never used them much: big hassle and the correction never
seemed to match my normal lenses well.

I'm trying to compare, in order of importance:

+ Performance in the hot hot Dallas summer
+ Transmitted light indoors
+ Fading time
+ Blocked light outdoors
+ Blocked light while driving\
+ Weight
+ Activation time
+ Price
+ Lifespan (2 years is what I'm looking for)

I would be getting anti-glare coat.

After research here and on the company's websites, I'm confused about
which would best work for me, *if any*. From what I can tell
Transitions III would perform poorly in Dallas. Transitions Quantum
mentions "Proven high-heat performance," but no specs. Are these
really that different from their III line? Corning SunSensors touts
"Excellent warm-weather performance."

And Rodenstock says their lenses "darken up to 50% in the car."

Any opinion? Waste of $$$? I was thinking of trying Transitions III
because my Costco offers them for $70 (lenses only), and I could
handle that as an experiment. But in Dallas that looks to be a waste
of $$$. Adding to my confusion the optometrist who I went to for my
new prescription last week liked his Transitions III, and I'm assuming
he lives in the same heat soaked city I do.

Finally, do all of these really take 5+ minutes to fade back?

Consider the Transitions Velocity. It's the latest and greatest (according
to the maufact) and claims 7times faster darkening and 3times faster
clearing over the widest range of clear-dark of the transitions line, and
the least affected by temperature. Basically a Transitions Quantum
technology in spectralite lens material. A good lens, but a little pricey.

I have a pair of transitions III and corning sun sensors.

The sunsensors get much darker in cool temps. Sometimes too dark. In
warm temps there is not as much difference but I give the edge to the
Corning. I have not tried the Velocity transitions.

BTW they are all poor in a car. To kill two birds with one stone I
have a pair of magnetic polaroid clips and Corning lenses. That way
when I drive I put the clips on and use them without the clips for
most other activities. Works great for me.

Hello, I have a question about the thinner lens, my formula is of -3.5 and I bought a Rayban mount type aviator, is a thin mount, but I don't know what is the thinner lens if the transition 1.74 or colormatic 1.6, thanks
