• Standard single vision (CR39) – This lens is both lightweight and budget. It is suitable for most rimmed & half rimmed frames and will tint well for sunglasses.


• Mid Index (1.56) – This low cost lens is 20% thinner than standard and will tint well. Recommended for higher + prescriptions. Over +6.00 dioptre requires a sun spec tint.


• Polycarbonate (1.59) – These lenses are both thinner and lighter than standard plastic. With 100% ultraviolet protection they are up to 10 times more impact resistant than plastic. Polycarbonate lenses are an excellent choice if you are after rimless, half rimmed and sports glasses.


• Thin (1.6) – Up to 40% lighter and 35% thinner than standard plastic lenses. Tough anti-scratch and anti-reflective comes standard.


• Thinner (1.67) – 45% lighter and 45% more thin than standard plastic lenses. You won’t find much thinner lenses out there. Because of the slimness, these lenses are suitable for most frames.


Thin and thinner lenses are recommended for prescriptions above +6.00 down to -10.00 dioptre.


• Thinnest (1.74) – Up to 60% thinner than standard plastic lenses. This is the thinnest plastic available. This lens comes with high-impact, scratch resistant multi-layer antireflection coating. These lenses are recommended for prescriptions from -2.00 to -10.00 dioptre.


Please note: Thin thinner and thinnest lenses are not suitable for sunglasses.


• Transitions/Photochromic (1.50, 1.59 Polycarbonate, 1.6 or 1.67) – These lenses darken on exposure to UV rays and sunlight protecting your eyes from UV rays. This saves you from buying a separate pair of prescription sunglasses. The darkening feature means you are always wearing the perfect glasses. Suitable for rimmed and half rimmed frames. (1.59 & 1.67 are suitable for rimless.)

Lenses guide:

Hard Coating (scratch resistant): This transparent, hard polyurethane coating will prevent fine scuffs and scratches which would mark an uncoated plastic lens.


Anti–reflection: This coating reduces discomfort from reflection and glare. The lens allows light to pass through the lens with less dispersion. For example it would benefit night time drivers by reducing street light and headlamp flair. Anti-reflection lenses allow other people to see your eyes more clearly making them cosmetically appealing.


Lens tints: Mainly used for sunspecs and come in a wide variety of colours. There are many benefits from tints such as full UV protection as well as a comfort tint to complement and match your chosen frame.

Further lenses information

Modern lenses are now made from different plastics which are much lighter and harder to break than the traditional glass lenses.


All these factors help, but choosing a lens to suit your prescription is equally important. Take a look through our lenses guide and you can't go wrong.
