Sunglasses work by blocking some of the sun's bright light and harmful UV rays from getting into our eyes. They have special lenses that are made to absorb or reflect the light. This helps us see more clearly and comfortably when we're outside on a sunny day. Some sunglasses also have polarized lenses that reduce glare from shiny surfaces like water or snow. That's why it's important to wear sunglasses when we're outside, especially on bright days!
