Night lenses

What is orthokeratology?

The term “night lenses” refers to orthokeratology lenses. Orthokeratology or “correction through corneal reshaping” is a principle that allows clear vision throughout the day without wearing contact lenses or glasses, thanks to lenses that are worn during the night.

A proven technology for over 20 years, orthokeratology has benefited in recent years from major innovations in both lens designs and materials. This technique is considered, among other things, as an effective solution to reduce myopia.

Safe and painless, adaptation to night lenses also has the advantage of being non-invasive and completely reversible: wearers can stop using them at any time and choose another correction mode.

Progressive remodeling

The reshaping of your cornea is done gradually while you sleep, for a minimum of 6 hours to ensure an effective treatment.

Clear vision every day

See life clearly: that’s what DRL® night lenses do! By regularly wearing every night, night lenses will allow you to maintain the same quality of vision every day.

    Frequently Asked Questions

    Any questions?


    Made to measure, DRL® night lenses have been specifically designed to be worn at night and are made of a high permeability material which enables a good level of oxygenation for the eye.

    No. These lenses are made to measure and perfectly respect the physiology of your cornea. Of course it is imperative to strictly adhere to the hygiene rules (handwashing before inserting and removing, and daily care) which are necessary for safe wearing and renew your lenses every year. Studies have proved that there is less infection risk from wearing night lenses than from wearing day lenses.

    Clear vision during the day will last for almost 16 hours. It is of course necessary to wear your lenses every night to maintain the same quality of vision every day, because when you stop treatment, the cornea returns to its original shape after 24 to 48 hours and vision deteriorates.

    Yes. A satisfactory result can be achieved in one week for myopic patients, and in up to 15 days for hyperopic patients. This can vary from one wearer to another. In any case, you must follow your ophthalmologist’s advice.
