What is methafilcon A?
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.
Is methafilcon a safe?
Hubble contacts are made with a material called Methafilcon A by Shine Optical Co. Very few contacts are still made with Methafilcon A and most optometrists won’t recommend products made from the material. It’s considered a bad material because it impacts how much oxygen is able to get into your cornea when in use.
Is Omafilcon B silicone hydrogel?

What does Filcon mean?
The FDA gives each contact lens material a generic name.
