My eyes don't work any better than my ears. I keep a small container of extra screws in the tool bag and don't even try to find the dropped screw unless I spot it right away. Even the ceiling fan screws ... almost every ceiling fan comes with an extra screw or two. Over the years I have never thrown one out and have lots of extra blade screws, blade mount screws, washers and metric machine screws all in one container.
