The reason we need to be super careful with hydrogen peroxide around our eyes is that it's just too harsh. It's like trying to wash a sensitive wool sweater with harsh detergent - it's gonna get damaged, no question. Our eyes are way more sensitive than that sweater, and using hydrogen peroxide can cause irreversible damage to the delicate tissues.
Now, you might be wondering, "But what about all the times I've used hydrogen peroxide to clean cuts and scrapes?" Well, here's the thing: your skin is way tougher than your eyes, and can usually handle a bit of hydrogen peroxide without any issues. But your eyes are a whole different story - they need to be treated with kid gloves, and hydrogen peroxide is just not a safe choice.
