Expressions Colors contact lenses from CooperVision are manufactured using a technologically advanced tinting process that create a more natural and realistic color change.  They are available in eight natural-looking colors:  Jade, Blue, Aqua, Green, Hazel, Gray, Blue Topaz, and Brown.  Expressions Colors contacts are monthly color disposable lenses.

Lens Material
The lens material, methafilcon A, is a random copolymer of hydroxyethylmethacrylate and methacrylic acid. The lenses are made by modifying  the uncolored methafilcon A lens by affixing a colored pigment on that portion of the front surface that corresponds to the iris. The colored pigments consist of carbazole violet, chromium oxide green, dihydrodinaphto brown, dihydrodioxo yellow, phthalocyanine green, iron oxide red, iron oxide brown, iron oxide black, phthalocyanine blue, and titanium oxide.
