Children & Blue-Light
Research has shown that 97% of children under the age of four use mobile devices and teenagers spend 6-7 hours per day on screens.

The first step to protecting your vision would be having an annual eye exam. If you or your children suffer from any of the above symptoms and spend hours on devices, be sure to mention that to your eye doctor so they can prescribe the correct lens for you.
