Sunglasses that use the latest technology

At Polaroid, we start by getting the basics exactly right. And that means investing in the development of the best lenses on the market. Our Ultrasight™ lenses are made of nine functional elements. At the core of the lens, is the polarizing light filter. UV light absorbers are bonded to both sides of the filter. These block all harmful UVA, UVB and UVC light rays. Shock absorbing layers are then fused to both sides of the UV absorbers, making the lens light, flexible and impact resistant. A scratch resistant layer on both the outer surfaces completes the lens structure.

UltraSight™ lenses, exclusively developed for Polaroid® polarized sunglasses, are made of nine functional elements. The core element of the lens construction is the polarizing light filter in the centre. UV light absorbers are bonded to both sides of the filter. These block all harmful UVA, UVB, and UVC light rays. Shock absorbing layers are then fused to both sides of the UV absorbers, making the lens light, flexible and impact resistant. A scratch-resistant layer on both the outer surfaces completes the lens structure.


Inside every UltraSight™ lens

thermofusion technology

It’s the process that makes them different

Thermofusion™ Technology is a step forward in optical manufacturing. It starts with convex and concave moulds that are smooth, hard and made from an alloy with high levels of thermal conductivity. Precisely designed, these moulds ensure that the lenses are optically correct – thicker at the centre and tapered toward the edges. By carefully controlling the temperature and protecting the polarizer with additional lens layers, the heat and pressure used in the process preserves lens efficiency. Our technology is also flexible enough to create lenses with widely different curvatures and the same careful optical fine-tuning.

 

Step 1: Lens is placed between the highly polished concave and convex moulds
Step 2: Heat and pressure are applied, precisely curving the lens for optical clarity
Step 3: The lens curve is set during the cooling cycle

Optical performance beyond question

UltraSight™ lenses meet all international standards:

  • European – EN1836
  • Chinese – GB10810
  • American – ANSI Z80.3
  • Australian – AS/NZS1067


In fact, these lenses also comply with Europe Class 1 Optics Standards, providing superior optical performance and clarity of vision.
