NXT generation

Lens manufacturers never cease to deliver in their quest for ever-better optical and visual quality and the offerings at this year's Optrafair were no exception. The quality of lenses currently on offer might make you think that technology can offer little more improvement. Not so. Manufacturers at this year's show had a plethora of improvements in materials, fitting, features and processes.

The stand of a sunwear manufacturer might not seem the best place to start when reviewing lens technology advances but Bushnell had a different idea. The driving lens specialist was showcasing its Serengeti Polar PhD. These lenses feature a polarised, photochromic lens made from NXT, the sunwear version of Trivex. The lenses also have Serengeti's Spectral Control which enhances colour and contrast to improve vision quality and cuts down blue light. The lenses come in Drivers brown or a grey CPG colour. Communications manager Dawne Warren of Bushnell said the product carried on the legacy of excellence in glass lenses but in the lighter NXT, opening up many more frame options.
