To go on a complete tangent here, chameleons also can't blink and I found a dissertation-level website only about how they can't blink and what the consequences of that are: https://reptilefriend.com/do-chameleons-blink/
But I initially thought that they can have their eyes blink independently, which brings me to my next point: In the anime My Hero Academia, one of the heroes, Erazure Head, has the ability to block someone's ability as long as he is looking at them, with the drawback that the effect ends when he blinks, which fucks up his eyes, because he doesn't blink during fights. And every time I see him, I just think to myself, if only that mf had learned to blink independently with his eyes, which I am sure you can train if you want to, he could've completely negated the drawback of his ability.
Then again, MHA is full of these little oversights, which definitely lessen my enjoyment of that anime. Take the heroine Alien Queen for example. She can spray acid from her hands, an ability she doesn't do very much with, which is why she is one of the less important heroes. She could however have trained to "sweat" acid to surround her body with an acid shield and if she had learned to spray her acid as a fine mist that the air can carry into your lungs, she could've become a walking violation of the Geneva conventions. Missed opportunity to have villains simply choke to death.
