It won't kill them.
Most of the time the contact lens prescription between the eyes is very similar, and the shape of the eye is very similar, and patients will not even notice!
If the prescription is different, they will usually be able to tell because one eye will be clearer than the other.
Hope this helps :)
They should be able to tell by how well they see.
They could always go back to the optometrist and have them figure out which is which, they should do that for free.
You can usually tell,by the fit and vision quality. I, for example, have two different perscriptions, so I can tell the difference.
If the perscription is the same and you don't feel any difference, then you should be fine.
You will know they are in the wrong eye because it will hurt really bad. I accidentally put the wrong contact in my eye and it made me really sleepy. I could not stop blinking and it made my eyes water really bad too. So make sure when you put the contacts in to put them in the right eyes. You can get some really bad infection if you keep putting them in the wrong eyes, it can affect your sight. I hope this advice helps. good luck. ~merry christmas~
