There is no doubt that computers can do a lot of harm to your eye health. When you sit in front of the computer for a long time, your eye muscles will be very sore and along with this symptom are neck pain, blurry vision and sometimes even a headache. Well, I think you may already have experienced these symptoms. Of all these symptoms, I think the most insufferable thing should be eye strain. Nowadays, eye strain is so common. If your work requires you to spend most of your time to sit in front of your computer, then I strongly suggest you to rest your eyes every an hour, even only for 10 min will be very helpful to your eyes.
