UltraSight Lens™ - The new premium lens from Polaroid Eyewear
UltraSight™ lenses made with Thermofusion™ Technology and 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.

Benefits consumers can enjoy
UltraSight™ lenses are the most extensively tested Polaroid Eyewear lens. They unite a highly-efficient polarizing filter with UV protection, shock absorbers and scratch-resistant elements. Wearers enjoy glare-free vision, visual acuity, UV protection and genuine durability – all in an environmentally friendly lens.
UltraSight™ are light, safe and strong enough to even absorb high impact.UltaSight™ lenses satisfy high velocity impact tests. These lenses can absorb the energy generated from the impact of a steel ball travelling at a speed of 100mph. That’s because of the unique lens composition. In impact situations, every layer fused within the lens disperses energy. That makes UltraSight™ incredibly shock-absorbent and delivers higher levels of safety in an accident.
A better process Thermofusion™ Technology is the innovative production process developed specifically for our UltraSight™ Lenses. Using it allows us to form lenses in a way that fully protects the polarizer that is at the core of the lens. With other techniques, the the plarizing film for the lens comes into direct contact with hot plastic – compromising its efficiency or forming the lens in a way that results in poor optics.
Thermofusion™ Technology overcomes both these issues by accurately protecting, shaping and tapering each lens during production. The result is the UltraSight™ lens, a breakthrough in quality and technology, delivering great polarizing efficiency and perfect optics.
Unrivalled technology
Created exclusively by Polaroid Eyewear, 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.

Lens is placed between the highly polished concave and convex moulds. | |
Heat and pressure are applied, precisely curving the lens for optical clarity. | |
The lens curve is set during the cooling cycle and then unloaded for use. |
| With Thermofusion™ Technology, we can create lenses that are optically correct and block glare with great efficiency. They’re also more scratch resistant, more impact resistant and offer 100% UV protection to the highest level. Exclusive to Polaroid Eyewear, the UltraSight™ lens is our highest performing lens ever. |
Reaching the goal of perfect optics
| 
Vacuum-forming produces a lens of uniform thickness which distorts vision.
| | 
UltraSight™ lenses, made with Thermofusion™ Technology and exclusively used in Polaroid Polarized Sunglasses, are tapered towards the edges for uncompromised, perfect vision.
| Improving visual acuity is a goal that shaped our research into the development of Thermofusion™ Technology. By investing into this unique process, we are able to create lenses that are thicker in the middle and pared toward the edges. These preserve visual acuity so wearers can accurately see sizes, shapes and distances perfectly clearly without any eye stress or headache.
Highest level of quality control
Our lenses are formed in Europe (Vale of Leaven, UK) and a team of quality experts ensure that the Thermofusion™ process is always delivering outstanding UltraSight™ quality lenses, that are accurrately and comprehensively tested before they are put into our Polaroid polarized sunglasses. Test them now and experience all the great benefits.
Eco-lens from renewable sources Customers want to go green. We already have. To create the high performing UltraSight™ lens, Polaroid Eyewear developed materials from sustainable sources. Our eco-polymer lens is made from cotton and wood cellulose compounds, both natural and renewable sources. By contrast, polycarbonate commonly used for lenses is derived from crude oil – a finite global resource. As part of our commitment to the environment, innovation and technology, Polaroid Eyewear is an official sponsor and proud supplier to PlanetSolar™, a groundbreaking project, promoting the potential of renewable energy. PlanetSolar™ has an ambitious goal - to sail around the world using solar power alone. Along the way, it offers educational exhibitions to explore better ways to protect our planet.
