Sunglasses
Ro-Sham-Bo eyewear has 100% UVA, UVB Protection, they are polarized and some even have mirrors. They also have an unbreakable warranty.
As a previous optician, I care deeply about sun protection for kids. More than 80% of our total lifetime sun exposure happens before we turn 18 years old. Our crystalline lens is also at its clearest when we are young, making the sun even more damaging as a child.
