One in two people have an condition that is a risk factor for sight loss

Speaking to Express.co.uk, consultant NHS ophthalmic surgeon Sai Kolli – based at University Hospitals Birmingham – explained how “the effect on daily living can be profound”. “Patients complain of redness, stinging, burning and grittiness of the eyes”, he said. A sign of dry eye syndrome, the condition can be caused by staring at a phone or computer screen for a prolonged amount of time.

Dry eye syndrome can also lead to the eyes feeling heavy and tired at the end of the day, irritated, scratchy, or watery.

Kolli said: “Sometimes, eyes can be red and overly watery – even though they feel very dry and sore.”

The condition can lead to fluctuating blurriness, an increased risk of infection, eye inflammation, and abrasion of – or a formation of an ulcer on – the eye’s surface.

Any damage to the cornea – the clear outer layer at the front of the eyeball – can lead to vision loss and blindness.

This can be achieved by “eating a varied diet with probiotics and a rainbow of colours of fruit and vegetables every day”.

Sharma added that maintaining regular hydration is useful, alongside “limiting caffeine and alcohol intake”.

In severe cases of dry eye syndrome, surgery might be needed.

Other suggestions for preventing dry eye syndrome from worsening include:

• Taking regular screen breaks
• Wearing dark sunglasses with high UV protection if you experience light sensitivity
• Avoid smoking
• Get enough sleep
• Blink more frequently when using screens or reading
• Wear a sleep mask to prevent worsening of symptoms at night.

If the eye condition is not managed, over time there is a risk of permanent damage.

People who persistently suffer from dry eye syndrome after a few weeks of using eye drops should seek professional care.

It is recommended to either visit your opticians or book an appointment with your doctor.
