ABSTRACT:
A composition including a neutralizing system and a sequestering agent is described which prevents the accumulation of inorganic deposits on contact lenses, particularly when used regularly in a conventional hydrogen peroxide disinfection regimen. The neutralizing system includes at least one reducing agent, a reductase, or both. The sequestering agent preferably is gluconic acid, a polymetaphosphate or their salts. Sodium hexametaphosphate is the most preferred sequestering agent; catalase is the most preferred agent for use as the neutralizing system.
