High Index Lenses

We pride ourselves on being the High Index Lenses Specialists, unlike most other websites and High Street Opticians we offer you the complete choice of both Plastic High Index Lenses and Glass High Index Lenses. We also offer latest range of Double Aspheric Lenses (Bi Aspheric Lenses) which are flatter than standard High Index (single aspheric) lenses, so there is less curvature is the lens. This results in a flatter design hence makes the lenses approx. 10% thinner in all lens indexes.

ThinLenses has wide range of High Index Lenses catering for most prescriptions.
