Square-eyed Spain: Office workers spend longer hours on computer than rest of Europe

Three-quarters of all workers who use computers or other electronic devices in their jobs suffer dry eyes, blurred or out-of-focus vision, neck and shoulder pains, joint pains, headaches and backaches.

The average office worker in Spain spends at least seven hours a day in front of a computer, more than anywhere else in the EU, the report claims.

Opticians warn that this could lead to serious eyesight problems.

As well as following recommendations on posture and screen height, medics say anyone whose job involves constant computer use should get up and walk about for five minutes in every hour and get away from their screens.
