how to photograph sunrise/sunset without going blind

[gordeaux]

How do people take photos of sunrises and/or sunsets without staring through the viewfinder so much that they damage their eyes?

Is there such a thing as an eyepiece filter that helps with this? (I'm using an EOS 10D).

During sunrise or better yet sunset, there is usually enough atmosphere to block most harmful effects of the sun on your eyes, however a good pair of sun glasses will help even more. Sunset is better because of the additional haze that is usually in the air.

When I take sunsets, I am more worried about my camera sensor.

In the below picture of which I took several, I basically set up my camera on a tripod, set the shot in the view finder and then only used the LCD review to monitor the position of the sun as I took each picture. Only when it had moved to much did I relook through the viewfinder. I took about 40 in this sequence, but I only liked this one.

In fairness, I should point out a bit of dark spots for about 5 minutes, but I get the same when I accidently look at my studio lights.
