How to combat Digital Eye Strain

We live in an increasingly digital world, and it is commonplace to spend hours at a time staring at a digital screen; be it a smartphone, tablet or computer. Workers in western countries spend at least 7 hours a day using a computer, which is almost 2000 hours every year with their eyes staring at a computer screen at work.
On average, people spend more time sitting in front of a computer than sleeping. This year marked the first year that time spent accessing digital media surpassed the hours spent watching television. What does this mean for your eyes? Studies indicate that 50% - 90% of computer users suffer from visual symptoms of digital eye strain.
