Simple precision

The basis of our SlideLens™ technology is a moving lens with a special profile, containing both positive power and negative power areas. This faces another non-moving lens with a similar shape. They cancel each other out.

As the two are moved across each other they cancel out less or more. The lens strength is adjusted to deliver clear vision instantly.

The very-best in hands-on manufacturing

To make our amazing lenses required us to invent a whole new way of making glasses. Our lens units are manufactured and assembled with the frames in a state-of-the-art facility in the UK. We’re investing to keep high-tech manufacturing expertise close to our home base.
