Free online contact lens timer
Set a clear countdown for contact lens soaking, disinfecting, or peroxide neutralizing. Pick the time from your solution label, start the timer, and get gentle prompts for rinse, wait, case care, and ready-to-wear checks.
Confirm the minimum time on your solution label, use fresh solution, and close the lens case before starting.
6 hours is a common neutralizing window for peroxide contact lens systems. Multipurpose solutions may use a different minimum soak time, often printed as 4, 6, or more hours on the bottle.
This timer is a reminder tool, not medical advice. Never put peroxide solution directly in your eye, and never wear lenses before the required neutralizing time is complete.
Many hydrogen peroxide contact lens systems need about six hours in the special case to neutralize before lenses are safe to wear. Use the timing printed on your own product first.
No. Use fresh solution each time you disinfect lenses, and follow the replacement and case-cleaning directions on the product label.
Some lenses can remain in storage solution longer than the minimum time, but product rules differ. Check the label for maximum storage time, re-disinfection steps, and when to replace solution.
