Disinfection means inactivating all pathogenic microbes but not
necessarily all microorganisms. It can be done thru cleaning and rinsing. In the case of contact lens, they can be
disinfected using only a 3% hydrogen peroxide solution – and not higher
concentration for safety. With the several commercial disinfecting solutions
for contact lenses evaluated in May 1983 – only 3% hydrogen peroxide has a fast
disinfection rate of 3-4 hours and has met the safety factor requirement as
suggested by FDA.
