It can happen. Systemic absorption as opposed to only local effects of eye drops can have a big impact, and if you’re trying to poison someone, you’re probably putting in most of a bottle of eye drops (5-15ml) instead of the few drops you would put in your eye, so potentially a ~100x higher dose.
Just thinking briefly about it, I think the more dangerous eye drops would cause lower blood pressure if taken orally or potential kidney problems depending on the drug.
It would probably have to be a high dose to seriously affect a healthy young person, but an older person or someone with underlying health issues or other interacting medications could more easily be affected.
