Abstract: A method for coating a plurality of optical lenses having at least one main surface at least partly covered with lenslets, the method comprising: —dipping (DIP) at least one first optical lens from the plurality of optical lenses into a coating fluid, —withdrawing (WDW) the at least one first optical lens from the coating fluid at a controlled withdrawal speed, —measuring (MEAS) a thickness of a coating layer deposited on the at least one first optical lens, —determining (ADJ) an adjusted withdrawal speed based on the measured thickness, and —repeating the steps of dipping (DIP), withdrawing (WDW), measuring (MEAS) and determining (ADJ) on at least other optical lenses from the plurality of optical lenses, using the adjusted withdrawal speed during the withdrawing step (WDW).

Abstract: The disclosure relates to a method for coating an optical lens having a main surface at least partly covered with lenslets. The optical lens is dipped in a coating fluid, withdrawn to reach an initial position defined so that said main surface faces towards a first, horizontal, direction, and the coating fluid coating said optical lens is dried. After withdrawing the optical lens and before or while drying the coating fluid, the optical lens is tilted to a final position defined so that said main surface faces upwards towards a final direction having an angle comprised between 80° and 100° with respect to the first direction, the first and final directions defining a vertical plane. Alternately or in combination, while withdrawing said optical lens, part of the coating fluid is removed from the optical lens by sliding said optical lens along a mechanical blade.

Abstract: This invention is related to an optical article, such as an ophthalmic lens, comprising a an acrylic substrate (1) coated with a specific hard-coat (2) formed from a composition comprising a hydrolyzed alkoxysilane, a colloidal metal oxide and a poly-glyceryl ether.
