Fortis Bays Polarised Sunglasses
Our brand new Switch technology allows the lenses to darken substantially in response to UV light. The lenses contain light sensitive molecules that change shape and colour when ultraviolet rays strikes them. The lenses will begin to lighten as soon as they are away from UV light, gradually returning to their original state. The lenses will start at a filter Category 2 light amber that will then “switch” to a filter Category 3 dark brown dependant on exposure to sunlight. Through a course of a session, whether that be at low light at dawn, stalking in the midday sun or sitting watching them fizz at dusk, your Fortis Bays with Switch technology will be the perfect shades for all conditions. Colours from pictures may vary.
The Fortis Eyewear Bays polarised sunglasses have been designed with a 22 degree wrap angle offering excellent side coverage to help eliminate the ingress of side light. The Bays are also the first model in the Fortis range to incorporate our zero hinge technology making these frames extremely lightweight & robust. These glasses perform well above their price bracket in comparison with other leading manufacturers.
The Bays are the first model in the Fortis range that integrate our XBlok technology. A reflective surface coating that offers additional (or extra) glare block to enhance vision. Not only does this technology provide maximum functionality but the reflective surface coating is also aesthetically pleasing, creating a mirror of colour. Available in a range of colours, each designed to filter out certain colours within the light spectrum to give maximum performance in any condition.
