I bought these glasses because I already knew the brand (the father has for him). They are funny with their flashy colors and eye protectors well. My son does not even try to remove them. He does not yet know them himself, but the fact that there is no sense is very convenient. By cons attention, they run small: my son has a big head, but at 7 months I took the waist 3 to be quiet and be able to take several years.
