I think I’ve read that they see better in the dark than we do, but their daytime vision is not fabulous, particularly at distance. If you make a sudden move 15 feet away, they might jump because they can’t be sure what it was that moved. Also, they don’t see well in extreme close-up, either, plus they have that center-vision blind spot at close range that all critters do who have eyes on the sides of their heads. That eye position means that they don’t have the depth perception that we take for granted, but they do have a wider angle of peripheral vision. Their sense of smell is great however, and makes up for a lot of the vision disadvantages.
What I can’t understand is why, with their limited clear-vision range and lack of depth perception, they don’t crash into, fall off, and trip over every solid object in the room. (Although that would explain how my girlbun kept winding up in the wastebasket!)
