Abstract
The plastic lens has the hard coat layer on a plastic lens base material containing at least sulfur atom and the organic anti-reflection film on the hard coat layer and further has a primer layer between the plastic lens base material and the hard coat layer. The hard coat layer comprises metal oxide particulates at least containing titanium oxide with rutile-type crystal structure and an organic silicon compound expressed by general Formula: R1SiX13. The organic anti-reflection film comprises a coating composition at least containing an organic silicon compound expressed by general Formula: R2nR3 mSiX24-n-m and silica system particulates of 1 to 150 nm mean particle diameter and has a refractive index which is lower than that of that of the hard coat layer by 0.10 or more.
