Thinner lenses

With such a great reputation and high standards each prescription is guaranteed to be produced to the highest quality. Standard CR39 Plastic (Hi Index 1.5) is recommended for prescriptions up to +/- 2.50 and is the most common type of lens today. It’s tougher, lighter and safer than standard glass lenses so more comfortable to wear for long periods. Thin and Light (Hi Index 1.6) is recommended for prescriptions between +/- 2.50 and +/- 3.00. They are up to 25% thinner than standard plastic lenses and 20% lighter, and will work well with thinner metal frames. Ultra-thin (Hi Index 1.67) is recommended for prescriptions of between+/- 3.00 and +/- 5.00. This lens will be up to 35% thinner than a standard plastic lens and up to 45% lighter, it means that more delicate frames can be used. Super Thin (Hi Index 1.74) is recommended for prescriptions higher than +/- 5.00. It is 50% thinner than a standard plastic lens, 50% lighter and is currently the thinnest and lightest plastic lens available.

Photochromic Lens

Photochromic lenses react in sunlight becoming darker in UV light. They are ideal if you want to combine sunglasses and prescription glasses in only one pair. This feature offers great comfort and can change from light to dark depending on the amount of ultraviolet light. When you are indoors, the tint will be clear and when you are outdoors, it will get dark depending on the exposure to sunlight. They block 100% of UVA and UVB and have an E-SPF (sun protection factor) of 25. These do not work whilst driving.

Photochromic extra active (Driving)

This lens reacts to sunlight , but goes extra dark, and is extra reactive behind car windscreens so is the choice of lens for drivers. The lens starts with a light tint (not clear) further enhancing all day comfort. They also block 100% of UVA and UVB light and have an E-SPF (sun protection factor) of 25.

Polarised lenses

Polarised lenses block reflected light from shiny surfaces reducing glare problems and improving colour perception and contrast. In driving they eliminate reflections from wet roads, windscreens etc. In sport they eliminate reflections from water and snow so are the ideal choice for skiers, snowboarders, water sports enthusiasts and fishermen. They block 100% of UVA and UVB light and have an E-SPF (sun protection factor) of 50 the highest available with any lens on the market.
