For how long should contacts be soaked if no specific time is provided by the manufacturer?

If no specific time is provided by the manufacturer for soaking contact lenses, the standard recommendation is to soak them for 4 hours. This time frame is generally sufficient to ensure that the lenses are properly disinfected and hydrated, making them comfortable and safe for wear. The soaking process plays a vital role in killing any microorganisms present and cleaning the lenses of debris or deposits that may have accumulated during wear. Thus, opting for a 4-hour soak aligns with best practices in contact lens care, maximizing the health and safety of the user’s eyes.
