Top 5 Tips To Combat Computer Eye Strain

Thousands of young people put vision at risk by straining their eyes and forgetting to visit the opticians. We asked the experts how to prevent eye strain and protect your sight

Eyesight is our most valued sense, beating smell, touch taste and hearing in a recent poll. But despite this, 17 per cent of Brits admit they haven’t had an eye checkup in the past three years.

And on a daily basis, an increasing number of us flit from work computer screens, to mobiles, to TVs to tablets and back again, so it’s no surprise eye strain is on the up.

“If you have a real problem, such as unexplained blurred vision or pain, discharge or redness in the eyes, it’s really important you go and see your eye doctor,” says Steve Schallhorn, Chairman of Optical Express’ International Medical Advisory Board (IMAB), which carried out the survey.

If your eyes are just tired from staring at screens and you’re experiencing tired eyes from day to day tasks, here are Steve’s top five tips for beating eye strain:

1. Take five. Give yourself a few minutes, get comfortable, close your eyes, take off your glasses if you wear them, slow down, relax and take deep breaths. Just for a few minutes to really give your eyes a break.

2. When you get home, avoid near work for a period of time. You’ve been working on a screen all day so don’t jump right into checking your email, or looking at your phone or even read for about an hour.

3. Change your lighting. You want a gentle, soft light that’s not too bright or high intensity, but still illuminates properly. Try dimming a light, or turning on lamp rather than the main light. See how your eyes feel – you don’t want to put them under strain from too little or too much light.

4. Blink. We blink less when we’re doing intense work and some of the eye fatigue can be due to dry eye that we might not even notice. Taking five can help but also blink, get in tune with your eyes and see how they’re feeling. If they’re dry, close them or if that’s not enough use eye drops.

5. Massage. When we work in front of a computer screen our forehead muscles get very tense and just a few minutes to massage the head, brow and neck, if you have someone to do it for you, can help ease the pressure.

During the day Steve advises specs-wearers to ensure they have the right prescription and a well-fitting pair of glasses to prevent eye fatigue.

And even if you don’t need glasses yet (by 65, 94 per cent of us will!), there are things you should do to prevent your eyes being over worked. These include lining your screen up comfortably, so your eyes are level with the top third of it, with you looking down slightly. Also, adjust the brightness of your screen. It should be bright enough to read the letters comfortably but not significantly brighter than the surroundings, as a contrast will mean your retina has to work too hard to compensate.

It’s recommended you have your eyes checked every three years, even if you have no problems as some conditions, such as glaucoma, which can lead to blindness, have no symptoms. For more about eye care, visit

Enigmatic Moray Agricultural Terraces Of Incas

One of the most visually stunning Inca ruins is at Moray, an archaeological site in Peru approximately 50 km northwest of Cuzco and just west of the village of Maras. In a large bowl-like depression, is constructed a series of concentric terraces that looks like an ancient Greek amphitheater. The largest of these terraces are at the center – they are enormous in size, and descend to a depth of approximately 150 meter, leading to a circular bottom so well drained that it never completely floods, no matter how plentiful the rain.

The concentric terraces are split by multiple staircases that extend upward like spokes of a wheel and enable people to walk from the top to the bottom of the bowl. Six more terraces, in connected ellipses rather than perfect circles, surround the concentric heart of Moray, and eight terraced steps that cover only a fraction of the perimeter overlook the site. The purpose of these depressions is uncertain, but the most widely agreed theory is they used to serve as ‘agricultural research station’.

Enigmatic Moray Agricultural Terraces Of Incas

One of the most remarkable feature of the site is the vast difference in temperature that exist between the top and the bottom reaches of the structure, which can be as much as 15°C. This large temperature difference created micro climates, similar to what is achieved in greenhouses in modern times, that was possibly used by the Inca to study the effects of different climatic conditions on crops.

It is no coincidence that the temperature difference corresponds to the natural difference between coastal sea level farmland and Andean farming terraces 1,000 meters about sea level. Furthermore, pollen studies indicate that soils from different regions of the Inca empire was imported to each of the large circular terraces. It is now believed that the Moray terraces were used by Incan priest-scientists to experiment with vegetable crops to determine which should be disseminated for domestic production to farmers with fields all over the Andean region.

Another enigma is the way how drainage for water flowing through the aqueducts worked. The lowest level is perfectly drained and never gets flooded even after incessant rains. It is suggested that there must be underground channels built by the depressions' bottom allowing water to drain. It is also argued that the bottom is over a very porous natural rock formation that enables water filtering toward the earth's interior.

We might never know why Moray was constructed, but the agricultural research station is a very likely possibility. Perhaps it is not surprising, since about 60 percent of the world’s food crops originated in the Andes, including hundreds of varieties of maize and thousands of potato varieties.
