Tired eyes: symptoms, treatments and causes

Tired eyes can have many different causes, including lack of sleep, overuse and reduced blinking.

When we concentrate on a task, we tend to blink less. As blinking refreshes and moistens the eyes, they become dry and tired without it. Symptoms of tired eyes include soreness, red eyes and blurry vision.

Tired eyes remedy

Tired eyes are usually nothing serious, and the best remedy is to rest your eyes, either by getting more sleep or taking regular breaks from focused tasks and digital devices.

If resting your eyes doesn't help, speak to your GP or optometrist, as your symptoms could be a sign of something more serious.

How to relieve tired eyes

The most effective way to relieve tired eyes is to rest. However, if you can't take a break or stop a task, there are ways you can help to soothe tired eyes at home or work.

Blurry or double vision when tired

As your eyes become tired, they can struggle to focus on objects, and you may experience blurry or double vision. Long periods of looking at a digital screen can cause computer vision syndrome (digital eye strain), characterised by eye strain, neck and shoulder pain, dry eyes, headaches and blurry vision (Source: BMJ). These symptoms should ease with rest.

Blurry or double vision may be a sign of a more serious medical or eye problem, so you should see your optometrist if it persists.
