Curve Technology

frame curvature – Optilabs curve technologyMost modern sunglasses, particularly those designed for sport, have a high lens curvature. This wraparound style looks great but the curvature can cause considerable lens distortion. Until recently, this meant a lot of sports frames just weren’t suitable for prescription wearers – something that naturally led to a huge amount of disappointment.

The good news is that we have developed a computer model to overcome these difficulties. By inputting your prescription details and the curvature of your chosen frames into our ‘Curve Technology Program’, a modification is calculated which allows for the extra curve. This minimises the distortion and allows you to wear sports sunglasses that previously would have been impossible to fit with prescription lenses.

As a result, we have been able to increase our range of sports frames and sunglasses which suffered from a similar problem. Fantastic news for all prescription wearers!


Thank you very much for the quality of your product and service. I purchased a pair of prescription sports sunglasses from you in April and they have been superb. I had been advised by some opticians that sports sunglasses would not work well with varifocal lenses, as the curvature of the lens would lead to a distorted image. Prior to placing my order with you I phoned for advice and was reassured to be told that if I ordered varifocal lenses and I wasn’t happy that I could return them to be fitted with single vision lenses. I placed the order for varifocal lenses fitted to your Rapide frames and this proved to be a good choice. These lenses work really well for me with a clear image and absolutely no distortion. When these glasses need replacing I know that I can order from Optilabs with complete confidence.

I had been after a pair of prescription wraparound sunglasses for many years but had always been advised by my optician that because of my prescription, and the curve of the wrap around frames, it was not possible to make them for me. On the recommendation of a friend I was put in contact with you and I’m writing to express my gratitude – thanks to Optilabs I am now, at long last, the proud owner of wraparound shades. I’m absolutely bowled over by the quality. I noted that your glasses come with a money back guarantee but I can safely say that I won’t be taking advantage of that policy as I’m absolutely delighted with them! Many many thanks for your excellent service. I will have no hesitation in recommending you whenever I can.

By making incremental adjustments to your prescription, our Curve Technology Programme minimises distortion on lenses for frames with a high curvature and so provides better vision.

Try before you buy

Buying a pair of sunglasses is an important purchase. Not only do the lenses need to give you the best possible vision, your frames need to fit well too. If you are unsure which frames will suit you, Optilabs offers a Try Before you Buy service allowing you to choose up to three frames and have them delivered to your home so you can make your choice – and ask advice from family and friends should you need to. All frame samples will be fitted with plain, non prescription lenses at this stage but you will be able to get a good idea of fit and comfort before you order.
