I had one eye done for a few years before i got the second done. Being a forklift driver at the time this was not a good idea as looking up at pallets above me made one side very near, the other side seemed to be miles away. this caused a few problems with me dropping pallets of bleach and booze!
In my favour i did not kill anyone but after dropping butter all over the truck (took 3 days to clean it ) i was banned from the forklift.
