Abstract
An optical article comprising a first layer of a transparent resin having a self-healing property; an antireflection layer consisting essentially of a non-crystalline fluorine-containing polymer disposed underneath said first layer; and a circular polarizer disposed underneath said antireflection layer. The optical article has anti-reflective and anti-glare properties and also has self-healing properties and scuff resistance imparted by a thin, multi-layered film. The optical article thus is effective in reducing reflection and glare.
