 Hydrogen Peroxide melts colour contact lenses?

"Hydrogen Peroxide disinfection melts colour contact lenses?"

Is this a myth or is it true?

I've not noticed any truth in it after experimentation,... but a lot
of people claim otherwise.

Who claims this?  H202 based disinfection systems are approved for almost
all lenses.

H2O2 might fade the colors a little in some lenses. "Melting" the lens is
absurd.

Some brand of colored contact lenses are surface treated, and I have
had patients using these who report that their lenses end up getting
"bleached" after long term H2O2 use for disinfection.

Most lenses now have the color underneat the surface, and are less
prone to this problem.  With most colored lenses being disposable
nowadays, I have not had any patients complain about this problem for
a long time.

I think a few of the older tinted lenses tended to "fade"  
w. the h2o2 systems.
But it can't "melt" the lenses.
