Ophthalmic article in particular for sunglasses

Abstract

The invention relates to an ophthalmic article (), in particular for sunglasses, comprising at least one substrate () and a photochromic filter compound (), the ophthalmic article () having a first transmission spectrum in an activated state of the photochromic filter compound () and a second transmission spectrum in a deactivated state of the photochromic filter compound, such that: ⋅—the first and the second transmission spectra at wavelengths lower than 380 nm is lower than 1%, ⋅—the first and the second transmission spectra have a relative first maximum between 460 nm and 510 nm, ⋅—the first and the second transmission spectrum have a relative first minimum between 560 nm and 610 nm, and where ⋅—Tis the luminous transmittance according to ISO_13666 in the activated state of the photochromic filter compound. ⋅—Tis the luminous transmittance according to ISO_13666 in the deactivated state of the photochromic filter compound. ⋅The lens has a reduced transmission in the blue between 400 and 450 nm and a reduced transmission around 585 nm. The lens provides a good contrast and reduces glare.
