Keratoconjunctivitis sicca is the medical term for dry eye disease affecting the cornea and conjunctiva.
What dry eye means
In this condition, the eyes either do not produce enough tears or the tears evaporate too quickly. The surface becomes irritated, which can make daily tasks like screen use or reading uncomfortable.
- Common symptoms include grittiness, burning, or a sandy feeling
- Paradoxically, eyes can water because the surface is irritated
- Vision may fluctuate, especially during long periods of concentration
- Air conditioning, wind, and smoke often make symptoms worse
When to see an eye specialist
Dry eye is usually long term but can be managed well with the right plan. Professional assessment identifies the main cause and guides treatment to protect comfort and clarity.
- Seek advice if discomfort or blur affects work, driving, or reading
- Treatment may include lubricating drops, gels, or prescription medicines
- Lid hygiene and warm compresses can improve the oily part of the tears
- Simple lifestyle changes, like taking breaks from screens, often help
