Contact lens solution should be changed daily. True or False?

• A. True
• B. False
• C. Sometimes in a week
• D. Never

Answer: (A)

Keeping lens storage solution fresh is essential because the liquid in the case can become contaminated with bacteria and other microbes after it’s been used and exposed to the eye and the environment. Reusing the same solution or leaving it in the case for more than a day creates an opportunity for these microbes to multiply, which increases the risk of eye irritation or infection when you insert the lenses again. Using fresh solution daily maintains a proper disinfecting environment for storing the lenses and helps keep your eyes safer. So the statement is true. After removing lenses, discard the old solution, rinse the case with fresh solution, fill it with new solution, and let the case dry between uses; never top off the old solution or reuse it.
