HOYA’s MiYOSMART Spectacles for Myopia Management Available in Suns

April 4, 2023

MiYOSMART Sun RangeBANGKOK — HOYA Vision Care’s MiYOSMART spectacle lenses for myopia management are taking on a new form: sun spectacle lenses. The latest line, dubbed “MiYOSMART sun range,” will reach 30 countries in the coming months with an official rollout starting this month. (They are not yet available in the United States.)

The photochromic spectacle lenses, MiYOSMART Chameleon, and polarized spectacle lenses, MiYOSMART Sunbird, were developed to slow myopia progression in children using D.I.M.S. Technology while providing protection from intense sunlight.1-5 These two new products, along with the MiYOSMART clear spectacle lenses that launched in 2018, give children the freedom to comfortably take part in the activities they enjoy indoors and outdoors without compromising their eyesight.

MiYOSMART Chameleon and MiYOSMART Sunbird both provide protection from intense sunlight, while simultaneously correcting the myopic refractive error and slowing myopia progression.1-5 The new spectacle lenses utilize the same D.I.M.S. Technology used in the award-winning6,7 and noninvasive MiYOSMART clear spectacle lenses, shown to slow myopia progression by 60% in children aged 8 to 13.3

Due to its HOYA photochromic lens technology, MiYOSMART Chameleon is an all-in-one solution to myopia management and protected outdoor activity. It rapidly adapts to the level of sunlight and fades back to clear indoors in seconds.8 Meanwhile, MiYOSMART Sunbird is the ideal addition to MiYOSMART clear spectacle lenses, for extra protection from intense sunlight and glare.1,9,10 It also offers vibrant colors and rich contrast in bright light, allowing children to fully experience the beauty of the outdoors.11

“Children’s vision is worth protecting. By acting today, we give them more opportunity tomorrow,” said Frederiek Ysebaert, Managing Director of the Pediatric Care Business Unit at HOYA Vision Care. “With the launch of MiYOSMART sun spectacle lenses, inspired by our discussions with eye care professionals, we can enable children across the world to spend more time outdoors while protecting their eyes from intense sunlight, maximizing the benefits of D.I.M.S. Technology on myopia progression.”

Alongside the launch of the MiYOSMART sun range, HOYA Vision Care will launch “Protect How They See the World,” a dedicated global campaign to raise awareness of the importance of outdoor time and sun protection in children. Spending time outdoors may slow down myopia progression in children,6,7 and as such, it is the most common recommended behavioral management for myopia given by eye care professionals.8 However, as the majority of lifetime sun exposure occurs under the age of 21, it is necessary to prevent long-term eye damage to children’s eyes with effective and reliable sun protection.1,9 This is particularly important for myopic children using atropine eye drops for myopia management and those who are light sensitive.2,10,11

From the launch in 2018 until the end of 2022, over four million MiYOSMART spectacle lenses were purchased by parents across the world.18 With the launch of MiYOSMART Chameleon and MiYOSMART Sunbird, HOYA Vision Care will continue to help fight and control the growing problem of myopia around the world.
