I experienced something very similar when presented with glasses to slightly correct my vision as a child. I found the world too sharp and distinct. When I looked at a tree each leaf stood out, while my experience had been that there should be no individual leaf, it should be blended.
I decided not to use the glasses and since my vision wasn't that bad I stumbled through. I realize as an adult now if I had just waited I likely would have acclimated to the situation.
