Instructions for maintenance, insertion and removal of night lenses

Impeccable hygiene and respect of the maintenance & handling instructions are essential for wearing lenses at night.


Instructions step by step

To avoid contamination, always wash and dry your hands thoroughly before putting on or removing your lenses.

In the evening, before installation, fill the lens with comfort drops or artificial tears without preservatives. A separate shade allows you to differentiate the right lens from the left lens: the purple shade corresponds to the right lens and the blue shade to the left lens.

In the morning, when you wake up, instill a few drops of comfort into the eye or artificial tears without preservatives, and wait 10 minutes before removing them.

Once the lenses have been removed, let them soak for at least 6 hours in an Hydrogene peroxyde solution: decontamination is essential to eliminate bacteria and ensure safe wearing.

Once a week, lenses should be deproteinized with enzyme tablets.

To deproteinize your lenses:


Place the lenses in the case baskets


Add a enzyme tablets in it


Soak your night lenses all day


Rinse your lenses and case thoroughly with saline solution before putting them back in your eyes
