Furthermore, if you look at the transmittance charts for most photographic ND filters you'll see that they typically allow a very high amount of UV and IR light to pass through. The OD5 solar filters block virtually all UV and IR light.
It's not a problem photographically since digital cameras have a UV/IR filter over the sensor, but unfortunately it's the kind of light that burns your eyeballs (without you knowing it)...

So live view would protect your eyes, but is the sensor safe? What about heat inside the lens? Does a 10 stop ND protect from that?
