Its not eyesight. Before a certaib age you cant understand whats happening on a screen. So your toddler seems in complete focus, but in reality he's just overwhelmed.
Plenty of parents already let their sub 1 year old watch an hour a day. I get it, its easy parenting, your kid freezes and shuts up for a complete hour, but you're fucking his/her brain development up.
Screens can impact eyes *cough* visual snow *cough* but that was mostly because of crt's. 1080p and up is fine.
