It's not the FPS that hurts, it's the energy in the bbs that hurt.
In a lot of countries, the safety limit is 1 joule of energy. 475 FPS with 0.20g bbs is 2.09 joules of energy. It doesn't matter if you switch to 0.30g bbs. That would equal 387.17 FPS at the same 2.09 joules of energy that the bb launches with.
