The biggest problem gettng safety glasses is that everyone wants to sell you stuff rated for arc welding. Unfortunatly arc welding does it's primary damage in the ultraviolet range and the blacksmith's forge in the infrared range---opposite ends of the spectrum!
So you are looking for the gas welding or foundry worker type of protective lenses---or wear protection against projectile matter and don't spend all your time looking into the forge! (Why I don't like gas forges at "eye" level)
I get full eye exams every year as a diabetic and after 25 years of hobby smithing there is no evidence of eye damage so far.
