Ophthalmic lens wearer`s head and eye behavior measuring method, involves determining lens zone when wearer looks at target, and calculating movement of head and eyes of wearer based on detected zone

摘要

The method involves providing a target and equipment of a wearer with a lens having two zones, where vision of the target through a zone of the lens differs from the vision of the target through another zone closer to the lens. A zone of the lens is determined based on the vision of the wearer, when the wearer looks at the target. Movement of head and eyes of the wearer is calculated based on the detected zone. An independent claim is also included for an assembly of non correcting ophthalmic lens.
