Comments on: DIY eco eyeglasses made out of a Sprite bottle

These Sprite bottle glasses could become the hottest fashion in green eyewear.

the ring is a way to take them off?

Ouch! - Pretty certain I don' wanna know what material he's recycling for underwear...

It's so you can clip them to your bag/belt/bracelet/wallet... neat idea actually. Wouldn't have the ring at the front personally...

If you zoom in, you can see a line down the middle of the ring. I think it's a key ring.

Skippie. Now I have a new and inexpensive way to look like yet another poseur ******. Any more bright ideas, guys? Like how to cut the perfect faux-hawk with a Weed Eater?

No UV protection, unless someone is making plastic bottles with that built in.

it does look like a key ring. i bet there is another one, on the other side of his nose, to keep the glasses in place.

and then i looked at the picture again, and realized i am an idiot.

If they offer UV protection and/or polarization, that'd be interesting.

According to a white paper by Milliken Chemicals (http://www.packagingdigest.com/contents/pdf/Milliken%20White%20Paper%20-%20UV%20Absorbers%20for%20PET.pdf), fairly standard PET absorbs UV from about 100 to 320 nm.

As a very sloppy rule-of-thumb (I'm not a doctor, and I'm not giving medical advice), UV-A (aka LW UV) ranges from 315 to 400 nm, and it's not considered particularly harmful to eyes. Shorter wavelengths of UV-B and UV-C (315 nm down to about 160 nm) is of more concern.

I couldn't find any info quickly on whether PET polarizes visible light.
