Do your glasses get so dirty that it's visible in a webcam image before you clean them yourself? In typical lighting conditions, I don't think my lenses' smudges are visible until well above the threshold where I'd clean them myself.

Is this not something you can determine with your own eyeballs?

Solved! Put up a blank screen. If it's snowing, get out the microfiber. If it's hailing, wash them.

Next up, a holographic display that corrects for your vision. Optionally, adjusts to changes in real time.

Next up next. Eyeglasses that automatically dispense your eye drops. (You need to look up for this to work)

OIMV (Order of invention may vary)

Reminder, everyone. Use your monitor in a well-lighted room. A bright monitor in a dark room causes eye strain. Lost the study, but I can speak from experience.

If one's glasses have not yet become smudged badly enough to notice, what would be the point of cleaning them?
