- calamari4065 3y agoWhen I was young, I was told a story about how native tribes used the star as a vision test for warriors. Only people with excellent vision could discern the second star. No idea if there's any truth in the story, but I wouldn't be surprised
- antognini 3y agoYou're probably thinking of Mizar and Alcor, which are at the middle of the handle of the Big Dipper. This was used as a vision test in ancient times and in the middle ages. A fun fact is that it is actually six stars. Alcor is a binary star system and Mizar is a quadruple star system.
- calamari4065 3y agoThat might be it. I was probably 10 at the time so I don't remember the details
- Amezarak 3y agoYes, nearsightedness is much worse in modern times. Many less people needed corrective lenses, even as they got older.
