NXT Polarized Photochromics

[grace angel]

Intercast has successfully combined its NXT Polar with its photochromic NXT Varia. The company offers the first sunlens that is photochromic, polarized and guaranteed unbreakable for life. The company states the polymer is patented and it is lighter, stronger, free of stress with superior optics and lower surface reflections and adaptable to designs unthinkable with other lens materials. I emailed the company for some parameters like the Abbe value, the index of refraction, tenstile strength and specific gravity. I've yet to get a response from them. Have any of you folks out there tried the lens or sold them and had any feedback? Or can anyone tell me any of the parameters i mentioned above regarding this lens? Thanks for any help.

You needn't look further than Trivex for your numbers. NXT is the same PPG polymer, marketed under a different name.

unbreakable?, i doubt it, under what guidelines

I would love to be that Optician who has someone come in with what I told them was unbreakable broken.

Intercast Europe Spa announced today that it has entered into long-term strategic licensing agreements with PPG Industries and Simula Inc. to utilize Simula’s family of high-impact resistant, transparent polyurethane materials in the prescription eyewear, and sun and sport lens markets ... Simula’s family of impact-resistant, transparent polymers have proved to be beneficial for use in transparent armor for vehicles, aircraft transparencies, bullet-resistant window glazing, eye- and face-protective shields and a wide range of other applications for the military and commercial markets ...

Don't say "unbreakable" ... just say "transparent armor" ...

After having made above statement, would you please make the patent number and the country it has been patented available to this forum? Thank you for providing the answer.

Also,

Utilizing their propriatary photochromatic monomer processing, do you know what percentage of ambient light is polarized?

Action Optics (a division of Smith Sports Optics, a division of Safilo) and Serengetti, have been offering photochromatic polarized technology for a number of years now. However, the compromize has been recognizing less effective polarization. I'm not sure who makes their lenses but I would probably be correct to guess they are outsourced.

You should have watched mythbusters tonight. "Bullet proof glass" Lanimated polycarbonate 1" thick did stop a 22, a 38 and a 44 mag. (note lanimated 1" thick, not 1mm eyeglass thickness). Now when shot with a 30:06 the projectile when clean though 2 sides of a box this thick without noticable deflection.

As to being the optician who said it was unbreakable. I have been in this position several times when we had the unbreakable fiberglass children's frames, and in the early days of flexible titanium (when the mfg.s made such claims along with "lifetime warranties". I did learn that these frames are all but unbreakable provide you tell momma that out of hearing of the child. If the child thinks it's unbreakable, you'll eat it in two weeks.

Also note poly is more our less unbreakable, too bad it isn't un scratchable. You give up somethng for everything you get.

I know I am bumping an old thread here......

We ran over a TRIVEX lens with a steam roller last week... Did not crack or chip.

I hope you got that on video, or at least some photos. Who was the sucker that got connned into wearing them?;)

Intercast is a lens manufacturer as a matter of fact they were recently sold to PPG. This for the first time gives PPG control of both plano (Trivex or NXT as the plano Intercast product is known), and Rx Simula Technologies material.

PPG had the rights world wide for prescription use of the material they call Trivex
Intercast had the rights world wide for the Plano lens market with this material.

NOT QUITE TRUE (unless this polarized NXT has been changed), when originally released it was a combination of thin poly polarized with cast NXT on the back surface. So Trivex was not the same.

as amazing as that is for the lens. where the heck did you get a steamroller?

I was pretty sure you were kidding but I had to look anyway.

A construction crew was installing a blacktop parking lot near our lab. They all thought it was pretty cool.

Do these lenses come in Finished version. I could only find them in FF lenses

[Craig]

big volume required

[LENNY]

Are they the prototype for Vantage?

[AWTECH]

It is not practical to make polarized lenses in finished due to polarized finished cylinder needs axis aligned relative to the polarized alignment. You need 180 SKU's in finished lenses in each cylinder power.

Make sense!
Thanks

Holy ancient thread, Batman!

I doubt its the record though...

[AngeHamm]

I had never heard of this lens until this thread was resuscitated. Very cool.
