Goblet cells produce mucus to aid tear film stability.

Explanation:
The mucous layer of the tear film is produced by goblet cells in the conjunctival epithelium. These cells secrete gel-forming mucins (such as MUC5AC) that coat the ocular surface, helping tears spread evenly, adhere to the cornea, and lubricate the eye. This mucous layer is essential for tear film stability and comfort, trapping debris and maintaining hydration so the tear film remains intact between blinks. The lacrimal gland and accessory glands (like the glands of Krause) mainly produce the aqueous portion of tears, providing the bulk of the tear volume. Moll glands are eyelid-margin sweat glands with a different secretion role, not the mucous layer.
