HOYA's proven patented Integrated Double Surface Technology enhanced with Intelligent Design by Extensive Analysis (iDea), is a unique combination of never before attained personalization and enhanced design accuracy resulting in a truly distinct design optimized for every individual.

The iDea design principle adds a whole new dimension to the optical correction of presbyopia. iDea involves the enhancement of HOYA Free-From design principles right down to the level of the smallest retinal ‘pixels’ by going beyond incorporating prescription powers, frame dimensions and positioning relative to the wearer's face. iDea also takes into account lifestyle aspects of the patient, the chosen frame and information about previous glasses worn via the iDentifier™ interactive consultation and selection program.

In practice, this comprehensive approach and correction optimization guarantees perfect spatial vision in the most literal sense and total support during any activity. Millions of different design variants ensure significantly more personalization than any other HOYALUX progressive lens.
