Reflex SV is a 74% water-content SiHy soft lens designed for even the highest prescriptions. Lathe-cut, Reflex SV has a unique aspheric front surface geometry to reduce thickness.
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

- Computer controlled design and manufacture ensure credible, consistent lenses over the complete range of powers
- All high powered lenses are manufactured with an aspheric front surface geometry to reduce thickness
Reflex SV is suitable for: –
- High minus powers
