For optimal eye care and health, it is recommended that a multi-purpose lens solution from a reputable brand be used often to clean the lenses. You can purchase our Largo solution from our store or visit your nearest pharmacy or supermarket. Lens cases are also necessary to store the lenses when they are not being used. Again, be sure to keep  the inside of the lens case clean and avoid leaving it uncapped as dust and other small debris may enter into the case.
