Durasoft 2 Colors (D2*OP) contact lenses from Wesley Jessen are easy to use and durable. They are vial contact lenses designed to change the color of dark eyes and are available in green, blue, grey and hazel. The lenses are designed to be worn as daily wear lenses.
Lens Material
The lens material, phemfilcon A, is a hydrophilic copolymer of 2-hydroxyethyl methacrylate and 2-ethoxyethyl methacrylate. The DURASOFT 2 ColorBlends (phemfilcon A) Hydrophilic Contact Lenses are made by modifying the uncolored DURASOFT 2 lens by affixing a colored pigment on that portion of the front surface of the lens which corresponds to the iris.
