If you've noticed your eyes feeling drier, more tired or more sensitive than they used to, you're not imagining it — and you're not alone.
Dry, uncomfortable eyes are one of the most commonly reported everyday health complaints in the UK, affecting an estimated one in three people over the age of 50. But age isn't the only factor — screen use, indoor heating, contact lenses and environmental exposure all play a role.
Here's what's behind it, and what actually helps.
Why Eyes Become Drier and More Sensitive Over Time
Age and the tear film — Your eyes are kept comfortable by a thin tear film that coats the surface with every blink. As we age, the glands that produce this film become less efficient, tear production decreases and the film evaporates more quickly. This tends to accelerate from the mid-40s onwards, and is particularly pronounced in women around and after menopause when hormonal changes further affect tear production.
Screen time — The average UK adult spends over six hours a day on screens. Under normal conditions we blink around 15 times per minute; during screen use that can drop to five, significantly reducing how often the tear film is refreshed. It's why eyes feel most uncomfortable at the end of a working day.
Indoor environments — Central heating and air conditioning reduce humidity, accelerating tear evaporation. Offices, flights and heated cars are all particularly challenging for eye comfort.
Contact lens wear — Lenses sit directly on the tear film and can disrupt its structure over time. Many wearers find discomfort builds progressively through the day.
Other factors — Wind, pollen, dust and certain medications (antihistamines, antidepressants, some hormonal contraceptives) can all reduce tear production or increase sensitivity.
Signs Your Eyes Are Struggling
- A persistent gritty or sandy sensation
- Burning or stinging, particularly in dry environments
- Redness and light sensitivity
- Blurred vision that clears with blinking
- Tired, heavy-feeling eyes towards the end of the day
- Watering — counterintuitively, very dry eyes often water as a reflex response to irritation
If symptoms are sudden, severe or accompanied by vision changes, consult an optometrist or GP promptly.
Styes: What They Are and How to Support Recovery
A stye is a small, tender lump on the eyelid caused by a blocked oil gland or hair follicle becoming infected with surface bacteria. They're very common, affect all ages and usually resolve on their own — but they're uncomfortable, and supporting the area properly during recovery helps.
Common triggers: touching eyes with unwashed hands, sharing towels or makeup, incomplete makeup removal along the lash line, and conditions like blepharitis (chronic eyelid inflammation) that increase susceptibility.
During recovery: apply a warm compress to the closed eyelid for 10–15 minutes, three or four times a day — the warmth helps the blocked gland clear naturally. Never squeeze or pop a stye. Keeping the eye area clean is equally important, and a gentle, naturally antibacterial eye drop can help maintain surface cleanliness without the alcohol or harsh preservatives that would further irritate already-sensitive skin.
If a stye isn't improving after a week, is growing rapidly or is affecting your vision, see a GP or optometrist.
Simple Habits That Help
Follow the 20-20-20 rule — every 20 minutes of screen use, look at something 20 feet away for 20 seconds.
Position screens at or slightly below eye level — this reduces how much of the eye surface is exposed to air.
Stay hydrated — mild dehydration is a surprisingly common contributor to dry eyes.
Take contact lens breaks — alternating with glasses during long screen sessions reduces cumulative irritation.
Use a humidifier in winter — particularly helpful in rooms with continuous central heating.
Why Choose Natural Eye Drops?
Many conventional eye drops contain preservatives — particularly benzalkonium chloride (BAK) — that extend shelf life but can cause irritation and surface damage with frequent use. For anyone using drops daily, a preservative-free formulation is generally recommended by optometrists to avoid this compounding effect.
Natural eye drops formulated with gentle, well-tolerated ingredients support eye comfort without the risk of preservative-related irritation — making them particularly suitable for sensitive eyes, daily use, and older adults whose eyes are already more reactive.
