Aqueous deficient dry eye: Aqueous tears are secreted by the lacrimal gland. The liquid portion of your tear film consists of these tears. Inflammation of the lacrimal gland, caused by some inflammatory disorders, can reduce tear production.

Evaporative dry eye: When tears vanish too rapidly, a condition known as evaporative dry eye can develop.

Mixed dry eye: Some individuals have both a lack of watery tears and unstable tears, a condition known as mixed dry eye.

• Painful sensations of stinging, scorching, or pressing around the eyes.
• A feeling of roughness or foreignness.
• Epiphora, or tearing, occurs because of dryness, which causes discomfort or irritation, and intermittently causes excessive fluid production.
• Sharp or dull discomfort can be confined to the area around the pupil, the back of the eye, or even the front.
• Unstable vision and comprehension problems.
• Heavy eyes, or having trouble opening your eyes.

Reduced tear flow

Reduced tear secretion is often caused by:

• Aging Sjogren’s syndrome
• Allergic eye disease

• Reduced blinking rate
• Issues with the eyelids, such as protruding eyelids and drooping eyelids
