Why does the lacrimal gland secete too much?

The lacrimal gland may secrete excessive tears due to various factors, including irritation from foreign bodies, dry eyes, or Allergies that trigger a protective response. Additionally, certain medical conditions such as infections, inflammation, or autoimmune disorders (like Sjögren's syndrome) can lead to overproduction of tears. Emotional responses, such as crying from sadness or joy, can also cause temporary increases in tear secretion.
