We are carefull to set the starting point of the varifocal lens for long distance vision at 5mm above the centre of the front frame panel (eye shape). This is the average. Pupil distance measurements can either be supplied by you when entering your prescription or we can set the PD at the average of 63mm (distance). 

You may order varifocals as

STANDARD POWERS: Sph's up to +/- 6.00 and or Cyl's up to +/- 2.00, without Prism's, at the price indicated in your Cart

NON STANDARD: Sph's above +/- 6.00 and or Cyl's above +/- 2.00 or with Prism, but not over Sph's 8 and or Cyl's 4) at an additional surcharge of £30. Upload non standard prescriptions (only method) on the Non Standard prescription entry option form (red) and make payment of the £30 on the surcharge submission form below. From then on your Non Standard prescription purchase will be charged as if Standard and as shown on your cart page. You can proceed and shop as if Standard. (if you miss the surcharge payment it can be made retrospectively, don't worry).You may also upload your prescription and send it to us before ordering and we will email you back telling you "Standard or Non Standard" if you are unsure.
