I cannot believe my eyes! I have recently purchased some back surfaced varifocals for the first time and am amazed with the difference to my sight. I can now even read the small print! I can fully recommend glassesframesandlenses.com.

By machining the varifocal shape into the rear surface of the lens, a much wider viewing angle is achieved resulting in a wider field of vision. Here's an example to demonstrate: With your eye 3 inches away from a keyhole, you will only see a limited amount on the other side of the door. However, if you push your eye up as close as possible to the keyhole you can see much more than you could previously. This in essence is the main design principle of the Bespoke Varifocal lens. In addition to this, the freeform design provides for a more even distribution of power across the entire lens reducing peripheral distortion and enhancing optical performance.
In addition to our Bespoke Varifocal lens, we also offer our Standard Varifocal lenses £59 and Premium Varifocal lenses £89. For further details on these see our guide to different lens types.
