A dry eye is a situation when the eye cannot produce enough fluid aqueous, and the condition is known as keratoconjunctivitis sicca. Its primary causes are
- advanced age;
- Specific health issues include Sjogren’s syndrome, allergic eye illnesses, rheumatoid arthritis, thyroid disorders, lupus, and vitamin A deficiencies.
