Contact lens solutions are specially formulated liquids used to clean, disinfect, and store contact lenses. They help remove dirt, debris, and proteins that can accumulate on the lenses, ensuring clear vision and comfort for the wearer. There are different types of solutions, including multi-purpose solutions, which can be used for cleaning, rinsing, and storing, and hydrogen peroxide solutions, which require a neutralizing step before lenses can be worn. Proper use of these solutions is essential for maintaining eye health and preventing infections.
