This concerns my Mazda 3s.
ok... ive searched this topic and found no resuilts and i know im not delusional. but as i was looking at my rear window from the inside and out, occasionally i can see a bunch of nickel/quarter sized circles that look like... pockets of air or something. they are whiteish or blueish im not sure.

i have not done anything to my rear window. no tint, etc.

anybody else notice this or is it just me???

thanks in advance,
James.

i think i know what youre talking about, im guna check on my car in the daylight....have you tried using windex or anything like that?

 

I think i have noticed the same thing before i tinted my windows, It is probably a clear film which is inside or outside to protect or make your glass stronger for impact. Oh, ya, the only time i have noticed it was during the day time. I can'r remember what i did but try to clean them with Windex "in my opinion may make these coins even more visible", or just tint your windows.

 

I have noticed these circles. I have them on my car now. They do not distract me and i mainly notice it when i am outside the car. Somtimes in the right light i notice them on the inside. All i do is clean the inside of my rear window and they go away. They will come back and you just have to keep cleaning them.

 

Hi,

If you are wearing polarized sun glasses, take them off. I was seeing the same "circles" in my rear window and moon roof. My wife thought I was crazy until she tried my polarized sun glasses on and saw the same thing.

I see them from the outside of my hatch but Im not driving a MAzda3 it looks kinda cool. Mine are patterned and they look like blueish grenesh nickle sized circles. Almost like soap was on the hatch. I notice more on cloudy days or twighlight.

 

87 Turbo II: i see those markings on my glass too...it does look kind of neat.

 

The circles on the windows that you see when the sun hits it is the UV protection and window tinting applied to the window. It is nothing to worry about. If you wear polarized sunglasses, you can see the circles better because the polarized sunglasses block out the same UV rays that the UV protection does in the windows..thus you can see the circles better with polarized sunglasses. Hope this helps!!

 

Just while we're on the topic about sun protection I want to sound smart by explaining another thing. If you look in a camera and see that the lense is purple, it isn't really purple but it's blocking a yellowish green that is the color of the sun and your eyes are so used to seeing it the sun looks white. Well if you take that color out of the spectrum you see purple. Look at the windsheild on a BMW, Mercedes, or in any review of a Bently in a magazene. They make cameras not see it because the color is so promenant you would see a nearly all white photo if there is any sunlight shining into the lense. It works best for blocking sunlight so that's why they use it on Bentlys and BMWs and stuff, it's not really purple tint but rather a "anti yellow" tint. and it doesn't make it any harder to see the road or other cars but makes the sin from above look dimmer coo huh?

Oh and all glas and 83% of plastics block 100% of UV rays by itself (that's why all glasses say block 100% when in reality no glasses allow 1% in even reading glasses) so I doubt the circles are added UV protection. Polarized lenses are just lenses with thousands of microscopic lines. Driving glasses are verticle lines to stop horizontal rays bouncing off the road, if you tilt your head when looking at the "glassy" effects on the road. Then put on driving polarized glasses and look it's still there, then tilt your head back to normal and it will dissapear. If you hold to lenses in front of each other and rotate it you will be able to see through it, then not, then see, then not every 90 degrees so I'm guessing that Mazda polarizes the rear glass if you cen see them better with polarized glasses on.

(oh and I say driving polarized glasses because standard polarized glasses are meant to block rays from the sky so those microscopic lines are horizontal to block verticle transverse light waves.)

heh thank you Mr. Key, the physics teacher that thinks his V6 mustang can beat my 7.
