The good news for spectacle wearers is that our prescription laboratory is able to fit spectacle lenses to a wide range of the designer sunglasses currently on the market. If purchasing a frame elsewhere for this purpose, please check suitability with us beforehand to avoid any disappointment. Ophthalmic Frames Rather than purchasing a dedicated sunglass frame, any frame that can be used for clear lenses can also be transformed into prescription sunglasses by inserting tinted lenses instead. For advice on tint colours to suit various coloured spectacle frames, please ask your Optician at the time of dispensing. Types of Tint click for examples Single Colour The most basic sunglass lenses are single colour tints, where the amount of light that passes through the lens is reduced consistently across the lens surface by the addition of a coloured dye. Conventional colours are brown, grey and green, although a wide variety of other colours are available. UV400 Block All sunglasses that we provide are supplied with a treatment that prevents the transmission of harmful UV rays to the eyes. This protects the eye from damage that has been linked to the formation of cataracts and macula degeneration. Graduated As an alternative to darkening the whole lens with a tint, the lens can be made darker at the top to provide more protection from overhead bright lights, and then either fade slightly or completely at the bottom of the lens to make reading and mobility easier. Bi-colour Rather than a graduated tint simply fading at the bottom of the lens, it can instead change to a completely different colour. This can be done to match the lenses that are being replaced in your current designer glasses, or simply to create a more striking effect. Polarised These are the most comfortable sunglass lenses for driving, fishing, sailing and other situations where reflected light and glare cause problems. A polarised lens blocks all of the light that is reflected from the surface of the road or water, enabling you to see the fish that got away more clearly and enhancing your safety on the road. Mirror Coating In addition to changing the colour of the lens by tinting, a mirror-finish can be applied to the front surface of the lenses. This further reduces the light that passes through to your eyes, and makes it harder for people to see your eyes behind the lenses. Silver Shadow Clean Touch Coating click for examples This semi-transparent mirror coating can be applied to a wide range of lenses. It can be used in addition to tinted lenses to create a look that can be sporty, casual or elegant. When added to non-tinted lenses the coating plays with the light, giving the wearer a mysterious gaze.
