Index finger knuckle: When your eye bothers you, most people rub it. If you make a poorly clenched fist, like you would use to rub your eye, the index finger knuckle with bent finger fits precisely into the pocket made by the meeting of your nose and eye. Rubbing there causes intense friction against the nasal white of your eye, abrading it and making it red. Try some artificial tears. If it doesn't help, see a doctor
