the sensor and not the shutter?
During metering, composition, and focusing, the mirror is down, so the light isn't getting to the shutter: it is reflected up to the pentaprism.
His eye, on the other hand, might be at risk if he's staring at the sun through a lens. Ack!
Optical damage to components is a function of power density. Your eye will focus collimated light to very small spot, so the power density goes up roughly 100,000 times when the light gets to your retina. Optical cements are capable of handling powers MANY orders of magnitude higher than your eye tissue, so you'd burn up your eye with just one millionth the power density it would take to damage your optics.
Of course in video cameras or in P&S cameras with live previews, you can damage the sensor because those *are* subjected to incoming light. (I can say from experience, never shine a high power laser into your brand new Nikon P&S . . . Doh!!! )
