Abstract
A lens including a lens base material, a hard coat layer that is laminated on the lens base material directly or via a primer layer and includes a metal oxide fine particle, an organic silicon compound and a polyfunctional epoxy compound as principal components, and an antireflection layer that is laminated on the hard coat layer and includes a porous silica fine particle and a second organic silicon compound as principal components.
Claims16
A lens comprising:
- a lens base material,
- a hard coat layer that is laminated on the lens base material directly or via a primer layer and includes a metal oxide fine particle, an organic silicon compound and a polyfunctional epoxy compound, and
- an antireflection layer that is laminated on the hard coat layer and includes a porous silica fine particle and a second organic silicon compound.
A lens comprising:
- a lens base material,
- a dyeable hard coat layer laminated on the lens base material directly or via a primer layer, and
- a porous antireflection layer laminated on the hard coat layer,
- said dyeable hard coat layer being dyeable via the porous antireflection layer.
