Many people spend the majority of the day looking at some sort of screen thanks to their job, whether it be a TV, computer or smartphone. By staring at these technologies you're doing your eyes damage, and it could lead to problems such as fatigue, dry eyes and may even make you short-sighted.

Worryingly, the levels are getting higher and David Allamby - a leading laser eye surgeon and founder of Focus Clinics, London, UK - reveals that within the next decade the number of people who are short-sighted could increase by a staggering 50 per cent.

He also notes that the more people look at screens, the more they complain of problems with their peepers.

Lucky he has some advice on how you can try and keep your eyes in top condition while still working hard.

A simple place to start is by not emailing your colleagues and instead making an effort to talk to them face to face, even if they are in another area. Focusing on a screen too much causes you to blink less, and as a result your eyes aren't getting enough moisture. The tears evaporate the longer you stare so by talking to your co-workers aloud, you'll help increase your blinking.

If your job is a solitary one and there are few people or no one to chat to, try the 20-20-20 rule. Mr Allamby advises that people look away from their work every 20 minutes and focus on something 20 feet in the distance for 20 seconds. This will help your eyes relax a little and test their strength.

"If you take a break from your computer screen and look in the distance, that gives the muscle inside the eye a rest," he explained to MailOnline. "It should prevent fatigue and dryness."

To make sure you don't forget, Mr Allamby suggests sticking a reminder in clear sight.

Some fresh air always helps too; as little as a ten minute walk during your lunch break can help break up your day and refresh your eyes. Natural light will also help wake you up as some workplaces can be either darker or lighter than normal.

"Daylight is the best light to prevent shortsightedness. That’s the only thing proven stop it," the expert added.

Even weak sunlight will help, as will keeping blinds up in your workplace to allow the light to seep in.

What you eat can add extra benefits too. Omega-3 and omega-6 are needed to keep your body healthy, but lacking in omega-3 will cause dry eyes.

Fish is full of it and eating something like sushi as little as twice a week can help. Alternatively, try flaxseed oil if you're not a seafood eater.
