Anyone done clear UV-blocking "tint" on windshield?

I'm giving this some thought on my Prius and Civic, anyone have experience?

Do shops do it?
Any problems with polarized sunglasses?

Of note: ALL window glass (not specially treated or tinted) blocks MOST ALL UVB (so called "redness rays"), but NOT UVA, or the "wrinkling rays". That's why people who drive a lot get worse wrinkles on the left than the right, without ever having gotten sunburned in their cars. Sun protection is a big thing for me, I'm training to be a dermatologist as we speak.

I believe windshield film is technically illegal everywhere, but so is anything under 70% VLT on our front windows here in CA... I've had 35% all around on my last two cars for years and no problems at all. I think the more "modded" a car is, ie: more likely to be carrying "young whipper-snappers" in the eyes of the police, the more likely you are to get pulled over and ticketed, but maybe I'm just lucky. That and if I do get pulled over, I instantly turn on all interior lights and roll down all windows, which is exactly what police like for you to do anyway, even if your windows aren't tinted - I read that tip in "The Speeder's Guide to Avoiding Tickets". If you have limo tint and make the cop walk up to your car not being able to see inside, you can bet he's going to be apprehensive about it, probably with his hand on his gun!

On to the Prius: I believe that the UV-blocking only applies to the side and rear windows, not the windshield, but I could stand corrected on this. I still want the darkening properties of 35% or darker tint on the side windows anyway, but the concern is the windshield. I know a lot of tint shop owners tint their own cars' windshields, but will they do it on customers' cars?

Good to hear the thing about polarized sunglasses. I don't mind the mild pattern on the side windows, but on the windshield that would be dangerous.

Even on the windshield? Reason I ask is that the "shade" of the glass on the windshield is quite different than the side windows.

Thanks for the tip - I know that most tint companies claim 99% UV blockage, is there similar info out there about the HSEA glass? Can't find anything.

With the Prius anyway, I'll probably not worry about the clear windshield, though I do like the privacy and heat reduction that side window tint provides, at least it'll be cheaper that way!

The clear huber (or equivalent) is pretty much what I am talking about... I know that filters out most all (say 99%) UVA and UVB, but the question is... is it overkill on the Prius? If the HSEA glass blocks 95% of UVA or more I'd say leave it be, but if it's like 50-75%, I would go the extra mile. I just can't find the info anywhere.

This is NOT true of all glass. For UVB, it pretty much is, but for UVA is is not... Most "normal" glass allows UVA to pass through fairly freely. I have noticed in my own practice a HUGE amount of people with what I call "differential aging", that is, wrinkles that are much worse on the left side of the face (or right side if chronic passenger).

So... This discussion might have little merit with regard to the Prius specifically, with the HSEA glass, but is a huge medical (skin cancer) and aesthetic (wrinkles) problem overall. I have helped hack off cancerous chunks of enough Southern CA faces to know.

Rocco - how is your day/night vision with the "clear-ish" huper on?
