What type of lens solution can be used for both soft and rigid contact lenses?

The type of lens solution that can be used for both soft and rigid contact lenses is the multi-purpose solution. Multi-purpose solutions are specifically designed to clean, disinfect, rinse, and store both types of lenses effectively. This versatility makes them a popular choice among contact lens wearers, as they eliminate the need for multiple products.

In contrast, Clear Care solution is primarily a hydrogen peroxide-based solution designed mainly for cleaning and disinfecting gas-permeable lenses; it is not suitable for soft lenses without an appropriate neutralization step. Saline solutions, although safe for rinsing, do not have disinfecting properties necessary for effective lens care and are typically used just for rinsing lenses before use. Hydrogen peroxide solutions are effective for disinfection but require careful handling and neutralization before lenses can be worn, which may not be convenient for all users.

Hence, multi-purpose solutions are the most practical choice for safely and effectively maintaining both soft and rigid contact lenses.
