We need to get your bifocal or varifocal lenses right, this is how it works *
When you order bifoclas or varifocals we send the frames out to you before making your prescription lenses. You will use the frames to take some important measurments. Next, you'll send back your frames free of charge so that we can produce your perfect prescription lenses. We know some other websites don't do this, but we think it's important to get your glasses right. Any questions, please do contact us!
What numbers do you need to provide us with from your prescription? *
Please select all of the numbers you can see information for on your prescription.

We need to provide you with a personal quote. *
Your prescription is slightly outside of the standard range for getting an online order right. We would like to provide you with the perfect pair of glasses, at an affordable price. Please contact us using the details on our website and we can provide you with an affordable quote that best meets your needs. It's quick, easy and it mean you'll get the right glasses for you.
Do you have one or two Pupillary Distance (PD) values? *
Some people might see more that one PD number on their prescrition. Measuring your PD is important and easy, please see our 'how to measure your PD' help section. If you do not add a PD measurement we will use the standard average 63mm for men and 60mm for women.

Add transitions lenses? *
Transition lenses are the lenses that darken in the sunlight and lighten in softer light or the dark. They offer both style and convenience, and can help protect your eyes from UV. Our lenses use genuine Transitions technology.
What colour transitions lenses would you like? *
Would you like to add Blue Shield Technology? *
Blue shield technology includes a blue light blocker to reduce exposure to potentially harmful light from extended periods using electronic devices like phones, tablets and laptops. It also includes an anti-reflective coating to reduce glare and increase the amount of visible light passing through the lens. Plus toughened surfaces reduce the amount and effect of scratches.

Want to add UV 400 protection? *
UV400' refers to UV rays at the top end of the UV spectrum, up to the 400-nanometre wavelength. Sunglasses with this level of protection block an even wider spectrum than the CE and British Standard models, making them the ultimate protection for your eyes.

Particular care is paid to the lower attachment in order to reduce un-spring weight from the shock which is already among the lightest in the market. The range of ride height adjustment is 8 mm, allowing the rider to customize the bike’s geometry.
In the shock absorbers for racing models market, the acronym XXF is a synonym for quality and technological innovation.
Development implied a reduction in overall weight and better response to the biker’s controls. Besides, the new ‘race ready’ set-up and upgrade of the adjustment of the inter-axis and the hydraulic spring-preload have proven to be key. As for innovation, damping ratio was improved along with stability at high temperatures. The 14-mm stem increases flowability, whereas the 30-mm piston reduces the movement of fluid masses. All these enhancements were aimed at reducing inertia and better controlling oscillations of the suspensions. Special attention was paid to the accuracy of adjustments, which are now available on the upper head.
XXF shock absorbers can be easily customized by replacing the XP compression and XS extension valves. Available set-ups are labelled on the body of the shock absorber.
When developing this racing shock absorber, the engineers' specifications were evolution and innovation. With a significant reduction in weight as well as an optimization of the set-up and the simplification of the setting options, an evolution was achieved. The interior of the damper is innovative. By using a 14mm piston rod, the friction could be significantly reduced and a 30mm piston reduced the amount of fluid to be moved. Together, this lowers the moment of inertia of the shock absorber and leads to a faster build-up of the damping even with a small spring deflection and low speed. The response behavior of the shock absorber has been significantly improved and thanks to the arrangement in the area of ??the damper head, all adjustment options are easily accessible. Even the length adjustment (max.
All functions of the damper have only one goal ... to give the driver the best possible grip and control and to ensure uniformly low tire wear. Only if the driver has absolute confidence in his chassis can he fully exploit the performance potential of his BMW S1000RR.
Compared to the standard version of the XXF 31 shock absorber, the spring preload is set using a hexagon screw directly on the damper head. This saves the handwheel and the associated connection hose.
