Those big eyes you have when you're born stay the same as you age
When we're born, we typically have large eyes that everyone feels the need to compliment our parents on. But, it turns out our eyes stay the exact same size as you age. Because our faces mature as we get older, they only seem like they are shrinking in comparison.
Quick fact about the human eye
Every eye has a small blind spot behind the retina where the optic nerve is. Most of the time, we don't know this because both of our eyes work together to fill those blind spots.
