Abstract
An optical element comprises an antireflective layer that is disposed on and in contact with a substrate. The antireflective layer has a refractive index of greater than 1 to less than 1.41 and has a pore size ranging from greater than 0 to less than 300 nm. The antireflective layer includes an outermost surface having a water contact angle ranging from greater than or equal to 70° to less than or equal to 120° as determined using ASTM 5946-04.
