Adaptive optical filter for spectacle lenses
First Claim
1. An adaptive optical filter for a spectacle lens, comprising at least two separate zones (10_M, 10_S), one being at least one upper zone and another being at least one lower zone, each of said at least one upper zone and said at least one lower zone being defined by an instantaneous value of at least one optical property,wherein said at least one optical property (CT) of at least one of said at least two separate zones (10_M, 10_S) of said adaptive optical filter is variable over time between a maximum value (CTMAX) and a minimum value (CTmin);
- wherein said at least one optical property is a light transmission coefficient (CT);
wherein a coefficient of transmission of said at least one lower zone is greater than a coefficient of transmission of said at least one upper zone.

Abstract
An adaptive optical filter for a spectacle lens, comprising at least two separate zones (10_M, 10_S), each being defined by an instantaneous value of at least one optical property. The optical property (CT) of at least one of the zones (10_M, 10_S) of the adaptive optical filter (10) is variable over time between a maximum value (CTMAX) and a minimum value (CTmin).

17. A spectacle lens comprising:
-
an adaptive optical filter having; at least two separate zones (10_M, 10_S), one being at least one upper zone and another being at least one lower zone, each of said at least one upper zone and said at least one lower zone being defined by an instantaneous value of at least one optical property, wherein said at least one optical property (CT) of at least one of said at least two separate zones (10_M, 10_S) of said adaptive optical filter is variable over time between a maximum value (CTMAX) and a minimum value (CTmin); wherein said at least one optical property is a light transmission coefficient (CT); wherein a coefficient of transmission of said at least one lower zone is greater than a coefficient of transmission of said at least one upper zone.
