What kind of mask and eye protection do I need for occasional repairs?

Ok I don’t build surfboards, but I have repaired my own in the past and probably will in the future. In my history of surfing (5 years) I’ve made 4-5 repairs. What kind of equipment do I need for the occasional repair? I don’t really have room for a full face mask, nor do I want to spend the money on one. I pretty much always sand by hand anyways as I don’t want to over sand.
