A surface treatment process comprises (a) providing at least one optical device; (b) providing a curable surface treatment composition comprising (1) at least one fluorinated organosilane compound comprising (i) a monovalent segment selected from polyfluoroalkyl, polyfluoroether, polyfluoropolyether, and combinations thereof and (ii) a monovalent endgroup comprising at least one silyl
moiety comprising at least one group selected from hydrolyzable groups, hydroxyl, and combinations thereof, and (2) at least one fluorinated organosilane compound comprising (i) a multivalent segment selected from polyfluoroalkane, polyfluoroether, polyfluoropolyether, and combinations thereof and (ii) at least two monovalent endgroups, each independently comprising at least one silyl
moiety comprising at least one group selected from hydrolyzable groups, hydroxyl, and combinations thereof; (c) applying the curable surface treatment composition to the optical device; and (d) curing the applied, curable surface treatment composition.
