If you have to use eye drops, lay down on the bed and lay the drop bottle on the bridge of your nose, turn your head sideways a little and the drop will fall into your open eye, without the chance of you touching your eye with the bottle tip.
I found that if you hold your bottom eyelid out and apply drops there instead of directly on the eye,you will squeeze most of the eye drops out of your eye.
(No one can keep from blinking their eye when something cold hits it)
