Stimulating cold-sensing corneal receptors to enhance tear production.

Explanation: TRPM8 agonists activate cold-sensitive corneal afferents, which increase basal tear secretion and blinking (and can modulate ocular surface sensation), improving tear film and relieving dry eye. The other options describe mechanisms of cyclosporine/tacrolimus (calcineurin inhibition), lifitegrast (LFA-1 antagonism), and lipid-based tear therapies (lipid-layer stabilization).
