Good eyesight was the ultimate trait Chad back in the day.

Until 1000 years there were no glasses or any vision correction.
Imagine being a short-sightcel back in the day with -4.50 dioptre unable too she schit. You would have to stay with the women gathering berries and carrying for the kids while all the perfect eye sight Chads were going on a hunt for wild beasts. Imaging coming back from a hunt with a wild boar on your back and all the women mirin you. Probably the goat feeling ever.
