Help with your Lens Options Here at internetspecs.co.uk, we have kept our sunglasses lens options simple and at a great price. Because of their high overheads, high street opticians need to charge you a lot for both the sunglasses frame and any alternative lenses required. Online opticians will often make high profits on just the lenses. We have chosen to do neither! Our overheads are not high so there is no need to have our prices high - good for you!• If you just require the original manufacturer lenses, please simply select 'Original Sun Lenses'. These lenses will be PLANO (non-prescription). Please don't select these lenses if you require prescription lenses. They're scratch-resistant, hard coated lenses and have ultra-violet (UV) protection against the sun. We usually whether the lenses are solid or graduated. Solid lenses have the same shade over the whole lens. Graduated lenses gradually become a lighter shade; starting with a darker shade at the top of the lens and going to a lighter shade at the bottom.• Our standard 1.5 Tinted Sun Lenses and our thin and lightweight 1.6 Tinted Sun Anti-Reflection (AR) Lenses are ‘fixed tint’ (they are always coloured and so are for day use only). They will absorb 85% of sunlight. Our 1.5 Tinted Sun Lenses come in 3 different colours: brown, grey and green, whereas our 1.6 Tinted Sun AR Lenses just come in brown and grey. Our 1.6 Tinted Sun AR Lenses are only available from us if you have a negative prescription (the Sphere (SPH) reading).
• Our 1.5 Nupolar® Polarised sun lenses are tinted and eliminate glare, offering 100% protection from harmful UV rays. They're ideal for those sunny sunrises and sunsets when you can be 'blinded' by the sun, even while wearing 'normal' sunglasses. Polarised lenses must not be worn while driving at night. They come in 3 different colours: brown, grey and green.
• Our 1.5 & 1.6 Transition® lenses (known as 'Photochromatic Lenses' and available in either brown or grey), change colour in sunlight, meaning that you can use them during the day or at night. They are temperature dependent, darkening better in colder climates such as Northern Europe (in snowy conditions, they become extra dark, due to the intense ultraviolet light). Transitions® need ultraviolet rays from daylight to darken, meaning they're not always suitable for behind a car windscreen (our Polarised lenses are good during sunny driving conditions - please see above). The lenses without anti-reflection (AR) coating are darker in sunny conditions, whereas with anti-reflection (AR) coating, they are better inside and at night because they are lighter in colour. The thin 1.6 Transition® lenses come with an AR coating. The higher lens index value (1.6) causes reflections to increase. Having an AR coating helps to eliminate this.
Please note: Our brown and grey 1.5 Transitions® have a more limited prescription range than we have for most of our other lenses. Certain prescriptions will require more expensive 'surfaced' lenses. If this is the case for you, we will contact you very soon after you place your order to ask if you wish to pay the extra cost for 'surfaced' lenses or, if you wish to upgrade to 1.6 Transitions® or if you wish to change or cancel your order.
• It's also possible for you to have clear lenses into the sunglasses frame (for those who really love the sunglasses frame but want to have them as prescription glasses). We have Clean & Clear 1.6 Thin & Lightweight Anti-Reflection (AR) Lenses* (Single Vision only). These lenses will be noticeably thinner and lighter than standard 1.5 or 1.56 lenses. (You may have noticed that our Cylinder (CYL) drop-down forms opposite for the left and right eyes only go up to -2.00. However, for our 1.6 lenses, if you have a negative Sphere (SPH) reading, we are still able to supply, for no extra cost, CYL's higher than -2.00, up to -4.00. You won't be able to input this onto our forms so please either upload a copy of your prescription to us or tell us in the 'Any Additional Information' form).• Our Clean & Clear 1.67 Extra-Thin Anti-Reflection (AR) Lenses are even thinner and more lightweight than our 1.6 lenses. (for those who really like the sunglasses frame but want to have clear lenses and use them as prescription glasses). They are great for any prescription but are particularly good for those who have a high prescription (sphere (SPH) reading above +/- 2). Our 1.67 lenses are always Aspheric. Aspheric lenses allow the lenses to be made thinner and flatter. (You may have noticed that our Cylinder (CYL) drop-down forms opposite for the left and right eyes only go up to -2.00. However, for our 1.67 lenses, if you have a negative Sphere (SPH) reading, we are still able to supply, for no extra cost, CYL's higher than -2.00, up to -4.00. You won't be able to input this onto our forms so please either upload a copy of your prescription to us or tell us in the 'Any Additional Information' form). • Our Clean & Clear 1.74 Ultra-Thin Anti-Reflection (AR) lenses are the thinnest and most lightweight plastic lenses available (for those who really like the sunglasses frame but want clear lenses and use them as prescription glasses). They are only available from us if you have a negative prescription (the Sphere (SPH) reading). We recommend choosing a 1.74 lens if your prescription is higher than -4.50 for the Sphere (SPH) reading (i.e: from -4.50 to -8). Our 1.74 AR lenses are also Aspheric which contributes to the lenses being thinner and flatter.
• Our 1.59 AR Polycarbonate lenses are good for sport as they are tougher than normal lenses. (for those who love the sunglasses frame but want clear lenses and use them as prescription glasses). They're know as 'plastic aluminium' - weight for weight, they're four times the strength of aluminium - the material is used for riot shields. Because they're 1.59, they're also thin lenses.Please note: Our 1.59 Polycarbonate lenses have a more limited prescription range than we have for most of our other lenses. Certain prescriptions will require more expensive 'surfaced' lenses. If this is the case for you, we will contact you very soon after you place your order to ask if you wish to pay the extra cost for 'surfaced' lenses or if you wish to change or cancel your order.* Occasionally, for those with a low prescription (sphere (SPH) reading around Plano (0) to 1) selecting a pair of semi-rimless (supra) sunglasses, we may have to use a thicker lens (1.5 or 1.56) to enable glazing to occur. Here is the technical bit! - for semi-rimless sunglasses, the edges of the lenses have to be thick enough to allow a groove to be cut to hold the nylon thread. On occasion, a 1.6 lens will be just too thin. Please be assured that we'll contact you before we do this to make sure you're happy with us using a thicker lens.* In the instance that you have a positive (+) prescription sphere (SPH) reading, you have a small pupillary distance measurement and you choose a wide frame, we may have to use a special lens (known as a ‘surfaced’ lens) to get the centre of the lens in the correct place. If this occurs for you, we will need to ask you for an additional payment. Please be assured that if this case arises for you, we will contact you soon after you place your order to ask if you wish to pay for the special lenses or if you wish to change or cancel your order.
