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 concerns in the UK, particularly among older adults. 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 might help.
Why Eyes Can Feel Drier and More Sensitive Over Time
Age and eye comfort — As we age, the glands that help keep the eye comfortable can become less efficient, and the natural moisture around the eye may evaporate more quickly. This tends to become more noticeable from the mid-40s onwards.
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 significantly, reducing how often the eye surface is refreshed. It's why eyes often feel most tired at the end of a working day.
Indoor environments — Central heating and air conditioning reduce humidity, which can affect eye comfort. Offices, flights and heated cars are all particularly challenging environments for eyes.
Contact lens wear — Lenses sit directly on the eye's natural moisture layer and can affect comfort over time. Many wearers find discomfort builds progressively through the day.
Other factors — Wind, pollen, dust and certain medications can all affect eye sensitivity and comfort.
Signs Your Eyes May Need Extra Care
- A persistent gritty or uncomfortable sensation
- Burning or stinging, particularly in dry environments
- Redness and light sensitivity
- Tired, heavy-feeling eyes towards the end of the day
- Watering — counterintuitively, very dry eyes sometimes water as a response
If symptoms are sudden, severe or accompanied by any changes in vision, consult an optometrist or GP promptly.
Simple Habits That Can 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-feeling eyes.
Take contact lens breaks — alternating with glasses during long screen sessions can reduce cumulative discomfort.
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 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 can support everyday eye comfort without preservatives — making them a popular choice for sensitive eyes, daily use, and older adults whose eyes may already be more reactive.
