<human>: I've heard that the sun is bad for your eyes. Is this true?
<bot>: The sun can be very bright and harsh, so it's important to protect your eyes when you're out in the sun. However, most sunglasses are designed to block UVA/UVB rays, which are the most harmful types of radiation from the sun. Sunglasses with a higher percentage of UV protection will offer better protection from both types of radiation.
