Yeah, normally if you aren't a "serious" archer meaning if you're not planning on hunting then it's okay to close one eye. However, by doing that you narrow your field so when you're out there like the MC hunting and shooting arrows in a battlefield then you never close one eye because you can miss the changes in the situation or your surroundings which is fatal. One mistake and your dead or you lose your prey.
As an archer I just had to stop by and point out the inaccuracy. You never ever aim with one eye closed!! Anyway, that bothered me so I just had to point it out haha
