NightFlex Relax

Our NightFlex Relax lenses are specially designed to support myopia management, particularly for individuals with low myopia. Tailor the optic zone diameter to each individual so that the reverse treatment zone is smaller than the child’s pupil diameter. This approach enhances the effectiveness of myopia management.

About product


As specialists in individual contact lenses for myopia management for over a decade, SwissLens is proud to introduce a groundbreaking innovation in our NightFlex Relax lenses. Our new back surface design redefines the myopia correction process, offering greater control and precision.

In this innovative design, the reverse zone initiates earlier than conventional designs, but with a higher compression factor in the reverse zone. This unique compression factor empowers us to correct myopia more effectively and increase the induced addition as needed.

Much like our renowned soft or rigid Relax contact lenses, NightFlex Relax design grants you the freedom to customize the size of the zone and the amount of addition. This customization ensures precise correction of hyperopic defocus according to your specific needs and individual measurements.

With NightFlex Relax, you are not only correcting myopia, you are shaping the long-term vision and eye health of your youngest patients.
