Does that not just mean the green strip across the top of the windshield? Not the whole windshield surely.

I just purchased a new 2011 Murano SV a couple of weeks ago. It's my first new car I have ever owned, and so far there is nothing I don't love about the vehicle.

I made the huge mistake of tinting the windows last week (wanted it even darker than the factory stained OEM glass) at 4% tint. Its all but impossible to see out the windows at night, because of the compounding factor of the tint and darkened glass.

Even during the day, it's a nuisance and not worth it. Will definitely have to get the job redone, especially now taht I realize my hatch is only getting 1% light through...(.25X.04).

Either way, this site is a great resource, and I wanted to thank you guys for sharing, I couldn't find this information (regarding the stock light transmittance %'s) anywhere but here.

A grateful new member to this forum,

To each his own i guess, i love my dark murdered out windows.

I am getting my front doors done tomorrow with the state legal (darkest) of 35%. So, am I reading this chart correct that once I put 35% on the front doors, they will have a Tv of approx 26% - same as the rear triangles and hatch (74%x35%=25.9%)?

[red kiosk]

That sounds about right. I had mine done this past spring at 35% too. Although it isn't legal in Illinois, something about SUVs with factory tints in the rear, can only do 50%. There's a picture in my gallery with a side view of my MO where you can get an idea how it looks. Also, an earlier one, same view, before I had the tinting done. Hope this helps and take care!

Dan, thanks for one of the most thoughtful posts I've read on the topic of glass tinting.

The thing some folks tend to forget is that your LIFE depends on being able to see out those windows - all of them.

Every state has different laws regarding the acceptable amount of tint on windows. Excessively dark windows are dangerous to you and also make law enforcement people nervous if they ever approach the vehicle. Both are huge negatives.

I researched this once and found a helpful site: Auto Window Tint Laws | TintCenter Window Tinting

Some states have no limitations, but most do. It's a good idea to adhere to them and not to exceed the legal limits for light reduction.

Congratulations on realizing that your eyes are telling you something important!

Wow, I knew that the windshield was tinted, but not so much that you could block 21% of the light! Also good to know that 100% of UV radiation is blocked by the windshield and a few other passes through the glass.

Sorry I have to ask what is Visible Ray Transmittance mean exactly?

Also what is the percentage that the front door glass is tinted at? My front windshield was replaced with an aftermarket one it very clear that it doesn't look anything like the factory one; its so clear that during sunny days my MO gets fairly hot from the sun beating in the windshield while the back which is tinted stays a bit cooler. I would like get my windshield tinted close to what my front door windows are, anything darker would be silly I think. as my front doors are lighter than my back, side windows, and rear hatch window.

Thanks
A.

Just look at the chart, the windsheild is tinted at 79% and the front windows are at 74%. Although i would let the tint shop correctly match them as materials have different properties and colors between brands.

Does anyone know if photochromatic lenses (glasses that turn dark in the sun) work with 100% UV blockage? I would hate to be driving in the sun and they don't turn dark! That's what they always tell me when I buy new prescription glasses....they won't work inside a car.

Photochromic lenses will not darken in a car (with all windows up) because they react to the UV light that is so effectively blocked by auto glass. I know, I keep a pair in the car.

The reason that the windshield is 100% blocking the UV is because it is laminated glass. The plastic interlayer stops all the UV which manages to pass through the glass.

Even clear window glass will stop most UV. It is just the nature of normal glass to not transmit UV very well. Fused silica glass transmits nearly 100% of the UV, but is never found in windows outside of laboratory settings because it is very difficult to manufacture.

This is right, I have to wear clip on sunglasses over my Transitions lenses when I'm driving.

My co-worker just told me that he got a new prescription and he told me there is a new product (and he has it) that transition while inside the car.

I also wear glasses but my transition NEVER turns dark when I'm inside the car.

BTW, I'm about to purchase a pre-cut windshield tint.. http://cgi.ebay.com/ws/eBayISAPI.dll...#ht_6556wt_907

Anybody here has a recommended other brand?

TIA

I've got 3M tint on all my windows including the windsheild, i wouldn't go any cheaper.
