Q1. How does a polarized lens work?

Light rays vibrate in many directions. As light passes through a polarized lens, the polarized film channels the light rays to travel in the same direction; thus eliminating unsightly glare, much the same way as a Venetian blind channels light.

Q2. What is the difference between polarized and tinted lenses?

Tinted lenses do not reduce glare. They reduce the intensity (brightness) of all incoming light. Polarized lenses selectively cut glare without reducing the intensity (brightness) of the incoming light. Thus a polarized lens will provide much sharper vision as compared to an equivalent tinted lens.

Q3. Do KBco polarized lenses provide protection against UV?

All KBco polarized lenses provide 100% protection from UVA and UVB transmission upto 380 nm. We use a system called E-SPF to grade our lens offerings. E-SPF is like SPF for your eyes with a higher number being better. The KBco product range provides an E-SPF of 25. We also provide the Xperio UV product range which has the highest E-SPF of 50.

Q4. Is it possible to get a clear polarized lens?

No, it is not. The amount of polarization a lens achieves is proportional to the density of the film. The lighter the film, the less polarization a lens can offer. Tinting a light polarized lens does not increase its polarity. It simply darkens the lens and reduces brightness. To achieve maximum polarization, you must use a lens that utilizes a dark (grey-3, brown-3 or grey-green) film.

Q5. Is a processing guide and tech data available for the Xperio UV and the KBco range of lenses?

Yes please check the lab resources section for these items.

Q6. What is the most effective way to demonstrate polarization?

Demonstrating with a polarized lorgnette. Have the consumer locate an object that is reflecting glare and then view the glare through the polarized lorgnette. The glare will simply disappear - a hands on experiment of show and tell.

Q7. What base curve ranges are KBco polarized lenses available in?

Curve selection is determined by lens design. Our range of base curves is optimized to leverage digital surfacing technology. For details by design please check the availability chart in the lab resources section.

Q8. Can I tint KBco polarized lenses?

It is possible to tint KBco polarized lenses, however it is very important to control the temperature of the tinting process, because too high a temperature can cause the polarized film to warp. However you cannot tint polycarbonate lenses.

Q9. Can I get finished polar lenses?

Finished polar lenses are available in non prescription/plano lenses only. All polarized prescription lenses must be surfaced so that they can be mounted with their axis at 180°.

Yes we offer Wrap Solutions®. Included in the Wrap Solutions® offering is the EOS Wrap® PAL, a progressive lens designed specifically for 8 base wrap frame prescriptions.

Q1. What is Transitions® Performance sunwear?

Transitions® Performance lenses become darker based on the amount of sunlight. They are generally activated by UV radiation. Transitions® Performance sunwear are adaptable polarized lenses that become darker or lighter based on the amount of sunlight.

Q2. Can I apply AR coating to Transitions® Performance sunwear lenses?

Yes you can AR coat Transitions® Performance sunwear lenses. It is generally recommended to coat the backside of the lenses.

Q3. Do Transitions® performance sunwear lenses have a scratch resistant coating?
