Fortis Bays Polarised Sunglasses

• These have been designed with a 22-degree wrap angle offering excellent side coverage to help eliminate the ingress of side light. They are also the first model in the range to incorporate their zero hinge technology making these frames extremely lightweight & robust. These perform well above their price bracket in comparison with other leading manufacturers.
• Their 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 strike 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 glasses with Switch technology will be the perfect shades for all conditions. Colours from pictures may vary.
