What do you mean by "a good conditional"?
Both the sentences you gave are fine if we're talking about conditionals. There are just some corrections I'd make:
If you get something in your eyes, you should rub your eyes them.
If your mom comes home, you should ask for her to buy you an ice cream.
They sound better this way, in my opinion.
Conditionals of the first type, generally, describe events that can really happen. Conditionals of the second type describe events that can hardly happen. Conditionals of the third type describe events that could happen in the past but did not happen.
Hope this makes it clearer.
