What four answers can tell you
Four taps will not tell you what is wrong with your eyes. My answers put me with the people who cover one eye before the kettle. You might be the one who already asked and got told you were fine, or the one with a bottle in the cupboard, or you are only just noticing. Any of those is enough.
If you are still checking before the kettle, try it for sixty days and see.
