After selecting your glasses lenses, consideration should be given to choosing a lens coating that best suits your requirements. Our highly qualified and experienced dispensing opticians at Zacks Eye Clinic in central London W1, provide detailed unbiased advice on spectacle lens coatings without obligation or pressure.
Glasses lenses can be uncoated, hard coated (so that they scratch less easily) or multi coated to minimise reflections from the lens surfaces. The latest combination coatings leave the lenses cleaner, tougher and clearer than ever before allowing people to see your eyes rather than your lenses. The most recent lens coatings are also available with filters to help with computer use, night driving and even to counteract the effects of aging.
‘Blue’ Computer Coatings
Nowadays, we spend more time viewing digital screens which are often equipped with powerful light sources emitting intense blue light that can cause eye strain. The latest ‘blue’ multi-coatings absorb high energy blue light thereby enhancing the contrast of digital screens and reducing visual stress and harmful effects of UV.
The very latest coating from Nikon Optical called SeeCoat Bright, is specially designed to counteract the ageing effects in the crystalline lens. Nikon claim that this new coating will give a brighter colour perception and improved contrast to patients with less colour sensitivity. The coating comes with Nikon’s usual scratch resistance warranty and incorporates an e-SPF (Eye Sun Protection Factor) to protect eyes from UV.
SeeCoat Drive lenses reduce the blinding effect of glare from light sources such as oncoming headlights and street lamps, when driving at night. SeeCoat Drive lens coatings incorporate an innovative filtering technology which also offers superior vision in the daylight, so they are great for driving during the day and night.
Traditional sun lenses reflect some UV rays from their back surface. A Sun coating is specifically designed to eliminate both UV and visible light reflected into the eye providing a higher degree of protection equivalent SPF 50+ and reducing the discomfort from glare.
Transitions lenses offer all the benefits of clear lenses indoors and sunglasses outdoors. They provide visual comfort by automatically adjusting to changing light conditions. This helps to reduce glare and eye fatigue. Eye health is also preserved because these lenses block 100% of UV rays.
In addition to providing protection against UVA and UVB rays, polaroid lenses give effective protection against the glare caused by reflected sunlight making them ideal for sports (especially those involving water or snow). Polaroid lenses also provide enhanced colour perception, improved contrast and greater visual comfort than basic tints.
