What Causes Dry Eyes? Common Symptoms, Causes & Treatment Options in Salisbury SA

7 Aug

If your eyes feel dry, irritated, or constantly watery, you’re not alone. Dry eye is one of the most common reasons people visit our optometry clinic in Salisbury, and it’s something we see year-round.

What is dry eye?

Dry eye occurs when your eyes either don’t produce enough tears, or the tears evaporate too quickly. A healthy tear film is essential for clear vision and keeping the surface of your eyes comfortable.

What causes dry eyes?

There isn’t just one cause. In most cases, it’s a combination of lifestyle and environmental factors:

Increased screen time
Phones, laptops, and tablets reduce how often we blink, which leads to faster tear evaporation.

Air conditioning and heating
Indoor environments, especially during hot South Australian summers, can dry out your eyes quickly.

Ageing
As we get older, tear production naturally decreases.

Contact lens wear
Long-term contact lens use can affect the stability of your tear film.

Medical conditions and medications
Allergies, hormonal changes, and certain medications can contribute to dryness.

Common dry eye symptoms

Burning or stinging
Gritty or sandy feeling
Blurred or fluctuating vision
Redness
Watery eyes
Sensitivity to light

How to manage dry eyes

Small changes can often provide relief:

Follow the 20-20-20 rule during screen use
Use preservative-free lubricating eye drops
Stay well hydrated
Avoid direct airflow from fans or air conditioners
Take regular breaks when reading or working

When should you see an optometrist?

If your symptoms are persistent, worsening, or affecting your vision, it’s time for a proper assessment. Dry eye can be managed effectively with tailored treatment, but it’s important to identify the underlying cause.
