Photochromic Tints

Photochromic Tints

photochromic_tints.jpgEasily the most popular type of tint we dispense, photochromic lenses darken when exposed to bright natural daylight, then fade again when indoors. This makes them a very versatile solution for glasses wearers who need protection outside but don’t want to carry around a separate pair of prescription sunglasses to use when necessary.

In strong direct sunlight the tint is just as dark and protective as a good pair of sunglasses, and indoors it fades to less than 10% light absorption.

Before opting for a pair, bear in mind that standard photochromics don’t work to their full potential in the car – the ultra-violet (UV) wavelengths that actually activate the darkening process don’t easily pass through a glass windscreen, hindering the reaction. However, the new Sensity Dark lenses (details below) are noticeably better in this respect.

Also infra-red radiation (heat) is a limiting factor to the photochromic process – so in hotter climes you may notice a slight deterioration in performance.

Hoya Sensity is our first choice photochromic tint.

Sensity – first launched by our favoured lens manufacturer Hoya in 2014 to provide wearers with the comfort they need all different light situations. Thanks to Stabilight Technology and its other innovations, this breakthrough product continues to be the foundation of the Sensity family.

Sensity Dark – these deliver extra darkness in the open air as a reaction to UV and visible light, offering better performance for outdoor activities. They will also darken more than standard photochromic lenses behind a car windscreen and perform better in super-intense light and high temperatures.

Sensity Shine – These lenses also deliver extra darkness outdoors, but in a unique way. They have a light mirror coating that is more intense in the light yet subtle when indoors. Sensity Shine is great for those seeking a more fashionable looking lens.
