Multi-purpose contact lens solution may contain various chemical additives such as cleaning agents, surfactants, chelating agents, buffers, biocides, disinfectants, and preservatives(1). Rinsing contact lens with multi-purpose contact lens solution may cause minor eye irritation or discomfort when wearing contact lenses.
