Abstract: The invention relates to an ophthalmic lens configured to exhibit a clear state and optionally at least one darker state. The lens has a front and a rear surface (Cx and Cc) respectively defining a front and a rear side of the lens, the lens having in the clear state (FS) a visual transmittance at an AOI of 0° greater than 81%, the lens comprising: - a substrate having a front and a rear main face respectively adjacent the front and rear surface, and - at least one multilayered interferential coating comprising a front multilayered interferential coating which surmounts the front main face and which comprises at least one absorbing front layer in the visible region. In said clear state, a total visual reflectance for the lens Rv_t_rear from the rear and front surface, measured from the rear side at an AOI of 35°, is less than 5.
