  1. Rinse your lens case with clean contact lens solution.
  2. Fill the lens case with fresh solution and screw it shut.
  3. Soak your lenses overnight to keep them moist and ready for another day. Never reuse old lens solution; replace it daily. Always use proper lens solution for cleaning and storing your lenses, and ensure they don't come into direct contact with water or saliva.

Daily lenses should not be cleaned or stored, as they are designed to be disposed of after each use.

Always wash your hands with warm water and antibacterial soap, and dry your hands on a lint-free towel before handling your lenses. At the end of the day, remove your lenses.

When you receive your lenses, match up the boxes to the correct eyes. Remove 1 lens pod from the strip, open it, and put on your lens.
