At a Glance
- Dry eye happens when tears are too few or evaporate too quickly.
- Screens, AC, ageing, contact lenses and some medicines are common triggers.
- Lubricating drops such as CMC or PEG/PG formulas provide relief.
- Persistent dry eye should be checked by an eye specialist.
Every blink spreads a thin, three-layered tear film across the surface of your eye. It keeps the eye moist, clear and protected. When your eyes don’t make enough tears – or the tears evaporate too fast – the surface becomes dry and irritated. This is dry eye syndrome, one of the most common reasons people visit an eye doctor.
Symptoms to recognise
- A gritty, sandy or burning feeling
- Redness and tired-looking eyes
- Blurred vision that clears when you blink
- Discomfort with contact lenses
- Paradoxically, watery eyes – the eye over-produces poor-quality reflex tears
What causes it?
Less blinking means more evaporation.
Air conditioners, heaters and fans dry the eye surface.
Tear production falls with age, and after menopause.
Antihistamines, some BP and acne medicines can reduce tears.
How lubricating eye drops help
Lubricating drops, or artificial tears, add moisture and form a protective layer over the eye. Common ingredients include carboxymethylcellulose (CMC), which binds water to the eye surface, and polyethylene glycol with propylene glycol, which stabilises the tear film. Lighter strengths suit mild symptoms; thicker formulas give longer relief.
Use your lubricating drops before long screen sessions or AC exposure, not just after symptoms start. Prevention works better than catch-up.
Lifestyle changes that make a difference
- 01Take screen breaks
Follow the 20-20-20 rule and blink fully.
- 02Use a humidifier
Especially in AC rooms or dry winter months.
- 03Wear wraparound sunglasses outdoors
They protect your eyes from wind and dust.
- 04Try warm compresses
A warm, clean cloth on closed eyelids for 5–10 minutes helps the oil glands that stop tears evaporating.
- 05Eat omega-3 rich foods
Fish, walnuts and flaxseed may help some people with dry eye.
If dryness continues for weeks, or there is pain, light sensitivity or changes in vision, see an eye specialist. Dry eye can be linked to conditions such as thyroid disease or autoimmune disorders.
Frequently Asked Questions
Can dry eye be cured?
Dry eye is often a long-term condition, but symptoms can be well controlled with lubricating drops, lifestyle changes and, where needed, treatment from an eye specialist.
Are redness-relief drops the same as lubricating drops?
No. Redness-relief (decongestant) drops shrink blood vessels and are meant for short-term use only. Lubricating drops are designed for regular use to treat dryness.
How often can I use lubricating drops?
Typically 3–4 times a day or as needed. If you need them very frequently, ask your doctor about a longer-acting formula.
