Myopic children who wear spectacle lenses need a solution that will slow myopia progression, as well as protect them from harmful UV rays and intense sunlight.

MiYOSMART Sun

Outdoor Time & Sun Protection

The importance of outdoor time and sun protection

91% of Eye Care Professionals recommend spending at least 2 hours outdoors per day1

Spending time outdoors may slow down myopia progression in children, 2,3 and as such it is the most common recommended behavioural myopia management solution given by Eye Care Professionals.4 It may be the simplest and cheapest intervention that parents can encourage right away.

Children’s eyes should be protected from intense sunlight when outdoors

Children are more susceptible to eye damage from UV light than adults, as the majority of lifetime sun exposure occurs under the age of 21, so it is especially important to offer them effective and reliable sun protection.5-7 This is because children’s pupils are larger and the lenses of their eyes are more transparent, which allows more UV rays to reach the retina.6 Furthermore, single-vision sunglasses may not be the most effective myopia management solution for myopic children.8,9
