摘要：

An optical system having a transmission pattern comprising at least a first zone Z1 extending from 380 nm to a first limit L1 between the first zone Z1 and a second zone Z2, and a third zone Z3 extending from a second limit L2 between the second zone Z2 and the third zone Z3 to 780 nm,wherein the first limit L1 is greater than or equal to 436 nm and the second limit L2 is greater than the first limit L1 and smaller than or equal to 487 nm；the average transmission values T1, T2, T3, in each zone Z1, Z2, Z3 are such as:T⁢2>；T⁢1+T⁢3/2, withT1 the average transmission over the first zone Z1,T2 the average transmission over the second zone Z2, andT3 the average transmission over the third zone Z3,T1 and T3 being greater than or equal to 3% and smaller than or equal to 70%.
