The RoZZ sunglasses are ideal for children between 1 and 4 years old. Their round shape will give your little ones a slightly retro look. Their hinge-free UNBREAKABLE frame is perfect for all activities and, because they're available in 2 sizes, they'll fit all faces for kids in this age group. The oversize category-3 lenses ensure optimum protection from sunlight. This category of lenses, less dark but filtering out 100% of UV light, makes them more comfortable for this age group as they learn to walk.
