Do you suffer from dry eye?
If your eyes often feel sore, gritty, watery or tired, especially towards the end of the day, you’re not alone. Dry eye disease affects millions of people and is one of the most common reasons patients visit an optometrist.
While effective treatments are available, prevention is always better than cure. By understanding what causes dryness and taking a few simple steps, you can significantly reduce your risk of developing persistent symptoms. Here are our top five tips for preventing dry eye:

Our 5 Top Tips
TIP 1 – Give Your Eyes Regular Screen Breaks
We blink up to 60% less when using digital devices, and fewer blinks mean the tear film isn’t refreshed as often — leading to evaporation and dryness. If you spend a lot of time on screens, follow the 20-20-20 rule:
- Every 20 minutes, look at something 20 feet away for 20 seconds.
- During these breaks, blink consciously and fully to keep your tear film stable.
This simple habit reduces strain and keeps your ocular surface healthier.
TIP 2 – Keep Your Eyelids Clean and Oil Glands Flowing
Healthy Meibomian glands, the tiny oil glands in your eyelids, are crucial for preventing tears from evaporating too quickly. When they become blocked (a condition known as Meibomian Gland Dysfunction, or MGD), dryness, irritation, and inflammation often follow.
A quick daily routine can make a big difference:
- Use a warm compress (like a heated eye mask) for 5 minutes.
- Gently massage your eyelids afterwards to help express the natural oils.
This keeps glands working properly and supports a stable tear film.

TIP 3 – Hydrate Inside and Out
Your body’s hydration levels directly affect your tear film. Aim to drink enough water throughout the day and limit excessive caffeine or alcohol, which can dehydrate the eyes.
In dry environments, especially with central heating or air conditioning, consider using a humidifier or taking regular breaks outdoors to reduce tear evaporation.
TIP 4 – Adjust Your Environment
Your surroundings play a bigger role in eye comfort than you might think. Try these adjustments:
- Avoid sitting directly under air vents or fans.
- Wear wraparound glasses in windy conditions.
- Use artificial tears before long flights or car journeys in air-conditioned environments.
These small changes reduce tear evaporation and help maintain surface moisture.

TIP 5 - Know When to Seek Professional Help
If you notice persistent symptoms, such as burning, grittiness, watering, or blurred vision, it’s important to get checked by an eye care professional. Chronic dry eye is often caused by Meibomian Gland Dysfunction, and over-the-counter drops alone rarely address the underlying problem.
A comprehensive Dry Eye Assessment can uncover what’s driving your symptoms and create a tailored plan to restore comfort. Advanced treatments such as Intense Pulsed Light (IPL) and Low-Level Light Therapy (LLLT) can significantly improve tear film quality and long-term eye health.
