Before washing one’s hands, one should not touch the opening of any open parts of the body, e.g. eyes, ears, nose etc. It is as well preferable not to touch these openings from the outside of them e.g. eyelids, however, touching them through a garment e.g. pj’s is permissible.
One should also be careful not to touch food before washing their hands, but if one did touch food, the food is permissible to be eaten. However, whenever possible, the food should be washed three times before eating it.
