Our kids’ optical glasses come standard with polycarbonate lenses which are lightweight and impact resistant. Polycarbonate lenses are recommended for adolescent use since they are the most impact-resistant and safe lens option for children. The polycarbonate lens includes an Anti-Reflective coating in addition to a scratch-resistant coating that is applied to the optical surface of the lens. We offer kids glasses in single vision prescription, sleep prescription, and non-prescription lenses for ages 4-8 (small) and 9-13 (large).
Our kids’ sleep glasses are made of High Impact 1.56 lenses, which are also lightweight and impact resistant. While the lens tint is more yellow than the Felix Gray proprietary clear lens, our sleep lens specifically filters the range of Blue Light that is most disruptive to our natural sleep cycle in the 440 nm - 500 nm range. They are clinically proven to act as a natural sleep aid while minimizes color distortion. A recent study found when participants wore our lenses, they had an increase in melatonin levels, less awakening during sleep, and evidence of improved cognition compared to when they wore dummy lenses.
