Children require sunglasses just like adults to protect their eyes from the sun's ultraviolet rays. They are more susceptible than adults to eye complications and require extra eye protection. More UV radiation passes through children's lenses because their eyes are still growing and unable to effectively filter out harmful substances, putting them at a higher risk of developing many eye problems. Additionally, children spend long hours outside, and research indicates that a person spends 80% of their life exposed to UV radiation before they attain age 18.
