Abstract
It is proposed a method for defining a design of an ophthalmic tinted lens provided with a turquoise blue ophthalmic filter. It is provided at least one optical parameter value that is prescribed with reference to a clear ophthalmic lens. At least one non-null optical power value is determined from said at least one prescribed optical parameter value. At least one reduction value is obtained. At least one reduced optical power value is calculated in function of said at least one non-null optical power value and said at least one reduction value. The ophthalmic tinted lens design is defined on the basis of said at least one reduced optical power value. Methods for defining a design of a first and a second ophthalmic tinted lens are also proposed. It is also proposed a corresponding ophthalmic tinted lens.
