What it is Filled

The clear salty fluid secreted by the lacrimal glands that lubricates and protects the eye, in three kinds: basal tears that continuously coat the cornea, reflex tears produced in response to irritants such as onion vapour or wind, and emotional tears shed in response to strong feelings, a response apparently unique to humans; tears contain water, salts, proteins, lipids and antibodies, drain through the tear ducts into the nose, and their deficiency causes dry eye.

Why it exists Filled

Let an agent explain tears and their kinds, relay composition and function from physiological sources, describe emotional crying with research attributed, and route eye or emotional concerns to appropriate professionals.

Distinguishing features Filled

  • Three kinds
  • Three-layer film
  • Immune components
  • Emotional tears unique to humans

What robots and AI may and may not do Filled

Must not

  • Treat a person's crying as data to be logged, scored or reported.
  • Infer a person's emotional state or truthfulness from whether they cry.
  • Recommend eye drops or remedies in place of an eye examination.
  • Record or share images of a person crying without their consent.

Only with a human decision

  • Any clinical assessment or treatment of tear film or lacrimal disorders.
  • Responding to a person in evident emotional distress.

May

  • Explain the kinds of tears and their function in protecting the eye.
  • Encourage a person with persistent dry, painful or watering eyes to see an eye care professional.

Moral aspects Filled

  • Crying is an intimate signal, and treating it as a measurement intrudes on dignity.
  • Emotion recognition claims built on tears or facial signs are unreliable and have been used to judge people.

Who is affected

  • People in distress
  • Patients with dry eye disease
  • People subject to emotion analysis

Owners Filled

Steward

Nobody owns it; the examining clinician answers for care of a tear disorder.
