Glasses for the little ones. Children's bodies are generally more delicate than those of adults because they are less developed and less accustomed to the effects of external agents. In the case of the eyes, the main external agent is solar radiation, which can cause short and long term damage such as cataracts. To avoid this, the quickest and most useful way is to use specific sunglasses for children like these in a fun blue-green tone and round frame with lenses adapted to their needs.
