In the comics the power is solar generated, but it builds up quickly
like filling a battery.
If he is in the a very long time, the power fades. Jean
was able to look into his eyes (they're brown)
on a few brief occasions when Scott was underground for too long.
He also has a pair of regular sun glasses that he wears in the comics
instead of his visor, we assume they're specially coated or something.
