A hydrophobic and/or oleophobic coating system for an ophthalmic lens having increased effective thickness and water contact angle. In one embodiment, the hydrophobic and/or oleophobic coating system comprises an anti-reflective coating applied to an ophthalmic lens, the anti-reflective coating comprising alternating layers of high and low index materials with an outer layer of silicon dioxide having exposed hydroxyl groups. A hydrophobic coating is applied to the anti-reflective coating, the hydrophobic coating comprising a silane with a hydrophobic group and fewer than three reactive groups capable of bonding to the exposed hydroxyl groups of the anti-reflective coating.
