I was wearing all-round closed safety goggles over normal eyeglasses -  
still a spark came in by the badly fitting area around the nose when using  
the angle grinder and melted a small spot on the inner surface of my  
optical eyeglasses (plastic, i was bending down so gravity made it land  
there).

Unless you do something drastic like for example put your head in a bucket  
and pot it in transparent resin (which might impede breathing and  
scratching your nose) there'll always be a way. Well... maybe not with one  
of those inflated plastic suits they use for work with dangerous diseases,  
but those don't seem especially resistant to mechanical impact and your  
neighbours might get worried if you wear one while working in your garage.
