Initial Lens Specification

If you know the lens dimensions you wish to fit, supply those to No7 and a lens will be manufactured to those specifications. Otherwise, call our technical help desk with keratometry readings, spectacle Rx and HVID and we will provide a lens for you to assess.


Assessment of Fit

The lens should give good comfort, centration and adequate smooth movement in all directions of gaze.


A Good Fit

A good fit should be:

  • Comfortable
  • Cover the limbus in all directions
  • Centre well even on upward gaze
  • Move freely on blinking with the lower lid pulled down – between 0.50mm and 1.00mm
  • Give sharp, stable keratometry mires immediately after blinking
  • Superior resistance to dehydration – sustains oxygen transmissibility and comfort throughout the wearing cycle
  • Computer controlled design and manufacture guarantee credible consistent lenses over the complete range of powers
  • All high powered lenses are manufactured with a unique aspheric front surface geometry to reduce thickness and provide exceptional comfort and oxygen transmissibility

Reflex SV is suitable for: –

  • High minus powers
