If 3% generic hydrogen peroxide is substituted for the solution in one of the FDA approved hydrogen peroxide care systems, what may occur?

Substituting 3% generic hydrogen peroxide for the solution used in an FDA-approved hydrogen peroxide care system can lead to discoloration of the lens due to the composition and pH levels of the solution. FDA-approved care systems have specific formulations that are optimized for lens materials, ensuring compatibility and proper lens care, including cleaning and disinfection.

When using a generic product that does not match the composition of the approved system, the chemical properties may differ and potentially interact negatively with the lens materials, causing discoloration or degrading the lens. These interactions can occur as a result of different stabilizers, preservatives, or pH levels that might be present in the generic formulation, which are not meant for those specific lens types.

In contrast, while the lens might become uncomfortable or the solution less effective with an inappropriate substitution, this does not specifically explain the immediate issue of discoloration. Therefore, substituting with an unapproved concentration or formulation can lead to lens wear and quality issues that are incompatible with the intended use of the lens and the care system.
