The Julbo Looping 3 Kid's Sunglasses are designed for children between the ages of 2 and 4 years. Children are actually more sensitive to bright light than adults, and damage to the eyes seldom gets better with age. Kids are never too young to start on a path to a lifetime of healthy eyes. Wrap around profile for optimal eye protection. No hinge frame eliminates the risk of pinching little fingers. Reversible frame, with no right side up, so kids can put the glasses on themselves. Altitude Spectron 4 lenses blocks 100% UV ABC and 95% visible light. Curved temples for secure fit. Flat elastic strap keeps sunglasses safely on your child's head. Includes carry bag. Fits children ages 2 to 4 years.
