For organic lenses

For aesthetical reasons or to realize solar lenses, a lot of lenses are tinted.
Our products allow to prepare dyeing bath, which heated, will bring you a fast, stable and uniform coloration.

They are formulated from carefully selected synthetic dyes, chosen for their dyeing ability and their ability to pass the rigorous tests required by ophthalmic standards.
