Sunglasses block which kind of radiation?

that's just wrong. some sunglasses may block UV but they are primarily to block visible light.

Actually, cheaper sunglasses do not block UV. Wearing them in harsh sunlight can damage the eyes. Primarily, sunglasses are for visible spectrums of light, however.
