• Tint Regulations

  Perhaps the most common use of tinted lenses is for driving. Contrast enhancement can certainly improve vision while driving, improving depth perception and the tracking of objects however care must be taken as there are legal restrictions which must be adhered to.

• Maui Jim Sunglasses

  Maui Jim sunglasses were born on the Hawaiian island of Maui nearly 30 years ago and were created to make all the colours of the island shine.  These remarkable lenses not only have the finest polarising filters but also have exclusive technology that replaces and renews the natural colours that are dulled by traditional sunglasses.  Andrew believes that sunglasses should be about protection, comfort and an enhanced visual experience.  Maui Jim delivers just that.

  The difference is impossible to miss.  Put on a pair of Maui Jims and instantly glare is gone and the harmful UV radiation that can damage and age the eyes is absorbed.  The world’s true colours come shining through like never before.  Every vivid detail is cleaner, bolder, richer, crisper and with more contrast and clarity.  These benefits are a result of Maui Jim’s patented, colour infused Polarized Plus®2 lens technology at work in an optically correct, distortion-free lens that’s also available in prescription in both single vision and varifocal forms.  Come along and try a pair of Maui Jim sunglasses today and bring your world to life!  Because life happens, Maui Jim offers an unequalled repair service on all its products along with a two year warranty against any defect in materials or manufacture.

• Drivewear Lenses

  A new development in both photochromic and polarising technology has come in the form of the Drivewear lens. Developed by Younger Optics and Transitions, this laminated lens offers patients the first lightly tinted polarising filter combined with a new visible light photochromic and traditional UV photochromic functions.

  In overcast conditions only the pale yellow/green polarising filter (approximately 35% LTF – Class 2 tint) is evident, providing glare reduction and contrast enhancement whist driving.  In brighter conditions, even though most windscreens filter out UV, the visible photochromic element will still darken and enhance reds and greens.  Outside the vehicle the traditional UV photochromic element darkens the lens yet further to approximately 15% LTF (Class 3 tint).  Andrew believes that this is a very useful lens for driving.  He uses a pair himself!
