NightFlex lenses are the saving grace for myopia up to –9.00 diopters and +3.50 diopters, with cylinder correction up to –2.50 diopters. Their magic begins with an astonishing 60-70% decrease in myopia after the very first night of wear.

Full correction is typically achieved within 3-4 nights, and your vision remains stable all day long after approximately 4 weeks. What’s remarkable is that this transformation is completely reversible and noninvasive, giving you the freedom to choose your visual comfort.

With NightFlex, fitting contact lenses has never been simpler. Our experienced design has been fine-tuned over the years to offer both effective myopia control and comfort for dry eye patients and individuals with comfort-related concerns.

Take control of the progression of your myopia in a comfortable and convenient way with NightFlex Orthokeratology lenses. It’s time to wake up to a world of clear vision, all day, every day.
