Abstract
A plastic lens having an anti-reflecting and hard coat layer is provided. The anti-reflecting layer is formed by coating a lens with a hard coat solution containing at least one oxide sol, hardening the coated solution to give a hard coat layer and immersing the lens into an acidic or alkaline solution to dissolve the oxide particles contained in the hard coat layer so as to make the layer non-uniform. The anti-reflecting effect of the formed layer is equivalent to that of a conventional anti-reflecting film consisting of at least three layers.
