Oté Clean provides a fantastic level of cleaning power for hard and soft lenses alike. Oté Clean uses a safe chemical formula which includes ordinary alcohol and non-ionic compounds. These compounds react with dirt from proteins or fats, as well as dust which accumulates on everyone's contact lenses, and work to remove them completely. Aided by the preservative Polyhexanide Biguanide, this leaves your lenses fresh and ready to use every morning, ensuring sharp and clear vision.
