Where are goblet cells most abundant in the ocular surface?

Explanation:
Goblet cells are mucus-secreting cells that form the mucous layer of the tear film. On the ocular surface, they are most abundant in the conjunctival epithelium, especially in the fornix and palpebral regions, where they contribute mucins to keep the surface moist and lubricated. The corneal epithelium contains very few goblet cells to maintain transparency for vision, while the retinal and iris epithelia are not goblet-cell–bearing tissues. So, the conjunctival epithelium is where goblet cells are most abundant.
