Unfortunately, you weren’t able to answer the majority of questions about the human yes and its structure. Perhaps, you’re interested in eye anatomy, yet your knowledge is still far from being perfect. If you want to actually know the specifics of the visual system, you need to learn a bit more. Practice makes perfect! Hopefully, you were able to remember a couple of interesting facts while taking this quiz! Will your friends pass it better? Share the link to find out!
