It's nearly impossible for me to wash my hands in most bathroom sinks without punching the sink itself on accident just trying to get my hands in the water stream. I usually have to rinse one hand at a time, sideways just to have the tiniest amount of room
In a different universe I'd sell stickers for people to buy and stick near any sink like this that's been misdesigned, something like "Warning, the interior designer designing this bathroom was a moron, and choose an inappropriately-sized tap for this sink".
Best of luck, I hope your hands heal quickly.
Hand eye coordination doesn't improve the amount of room between the water stream and the sink, but as your comment appears to be in bad faith I'm sure you already know that.
Perhaps your hands are 4cm long so they fit just fine?
It would be nice if there was more infrastructure for it.
