  1. Refill

    Considering the circumstances, you can still make an attempt to reuse your contact lens. Without touching your lenses, refill the solution in the case and make sure the whole contact lens is soaked in the solution. When they are dry, they are prone to be damaged, therefore it is recommended not to touch them.

  2. Wait

    Leave them for 24 hours, let the contact lens absorb the solution.

  3. Check

    After they are restored to their original state, please inspect your lenses closely for any tear, damage or notch. If they appear fine you can wear them but remove it immediately if you notice even the slight discomfort. Microscopic scratches on the surface of contacts could lead to permanent scarring of the cornea.

Please do not try to reuse lenses that you suspect of contamination. Broken lens cases, cases that were improperly sealed or lenses that were dropped off and dried out must never be reused again.

To maintain the very basic care of your lenses, use only fresh contact solutions every day. Other than that, it is recommended to regularly clean and replace your storage case every three months.
