•Make a FITMENT TOOL by cutting out a cardboard box using the sunglasses size that corresponds to your child’s age, using our pictured example shown above.
•Frame width = Arm length (for example, 110mm frame has110mm long arms.)
•110mm = 4 +1/4 inches
•115mm = 4 and 1/2 inches
•120mm = 4 and 3/4 inches
•Please make sure the arms are not too long and stickout far behind the child’s ears. This will make wearing them impossible in a stroller or in a car seat, as the sunglasses will pop off the baby’s face.
•We also highly recommend buying snug fitting sunglasses, as they stay put much better on the face. Purchasing larger sunglasses "to grow into" often leads to ill-fitting sunglasses, which your child will refuse to wear.
