Abstract
Disclosed herein are photopolymerizable compositions and formulations that comprise photochromic dyes, photochromic blue light blocking dyes, permanent dyes, permanent blue blocking dyes, and/or their combinations. In some variations, these formulations are suited for example, for sandwiching between lens blanks to form semi-finished lens assemblies to form a tinted lens useful in sunglasses. The formulations are also suitable for correcting optical aberrations, and may provide a photochromic effect when exposed to sunlight.
