Have you ever looked up at the night sky and wondered if your eyes were enough to capture all it has to offer? Spoiler alert: They’re not!

While our eyes are absolutely amazing, they are also full of flaws. Nearsightedness, astigmatism, and even pesky floaters! But did you know these same flaws are mirrored in the world’s most advanced telescopes?

In this episode, I discuss common eye deficiencies and explain how they affect our ability to observe the stars. I compare them to the optical imperfections in telescopes, such as chromatic and spherical aberration. 

Tune in to learn more about nature’s first telescopes! 

This episode is part 2 of a series where we’ll uncover even more intriguing insights about the connections between our eyes and telescopes, so stay tuned!
