ThinLenses are the High Index Lenses Specialists. Unlike most other websites and High Street Opticians we offer a comprehensive range of High Index Lens options. The latest innovation in High Index Lens technology is Double Aspheric Lenses. Standard High Index Lenses are only surfaced on one side. Double Aspheric Lenses, also known as Bi Aspheric lenses, are surfaced on both sides of the lens giving them a much flatter & thinner look.

Disadvantages of Double Aspheric Lenses
