The user who buys glasses and contact lenses must do so under the prescription of an ophthalmologist, to whom he/she visits regularly for an eye check-up. The graduation of the product to be purchased must be the one prescribed by the professional, since introducing a different graduation to the one prescribed could cause damage to your health, being the sole responsibility of the user.
We recommend that to keep your reusable lenses in good condition, clean and disinfect them daily before and after each application with specific products and store them in optimal conditions. Store them in a solution with disinfectant, do not leave them only in saline solution as this does not protect against contamination and consequently could cause an eye infection.
