Preventive measures emphasize protecting the eyes from UV radiation by wearing glasses with a special coating to protect against UV rays.

yes it can

to prevent it put UV coating on it

Yes, the imaginary component of the refractive index is much lower then for silver or gold. Therefore there's less absorption. or if you prefer it's plasma frequency is at 77nm much lower then the other two
