Double side progressive lenses

Twice is the new individual progressive lens with double surface, that delivers an exponential increase in visual acuity in all fields of vision.

By taking account of all the individual parameters of relevance for the prescription (corneal apex-lens distance, pantoscopic angle, frame design and wrap angle) combined with information about the material and refractive index of the chosen lenses, it is possible to create a totally personalised lens, dramatically reducing the difficulties associated with getting used to progressive lenses.

Thanks to the distribution of power over both surfaces, Twice offers extremely sharp peripheral vision. 
Twice features a variable base curve, an innovative front surface providing the ideal optical geometry in all the areas of vision.
