Abstract
The present invention relates to a light polarizing ophthalmic lens comprising a substrate made of organic glass and an optically transparent composite film deposited on the front main face of the substrate, said transparent composite film comprising a latex layer having an outer main face provided with parallel microgrooves, and a polarizing dye material filling at least partially the said microgrooves. The present invention also relates to a process for the manufacture of the light polarizing ophthalmic lens.
