You may not even realize it, but when you are really into your work, you may end up forgetting to blink. This is because you are concentrating so hard on what you are doing. When you don’t blink, your eyes are going to become dry and itchy, and this is a sure sign that you have been working your eyes too hard. It may be wise to also stock up on some eye drops to keep your eyes lubricated at all times.
Taking frequent, short breaks is not only good for your eyes, it is also good for the rest of your body and your mind. If you are going to be spending several hours in front of a computer, it is a good idea to get into the habit of taking short breaks every 10 minutes or so. These breaks can be as short as 10 seconds, but just long enough to look away from the screen and give your eyes a quick break.
Do Eye Exercises
There is a simple eye exercise you can do that will help to reduce eye strain, known as the 20-20-20 rule. Basically, every 20 minutes or so, turn your attention away from the computer, and focus on something that is about 20 feet away for approximately 20 seconds. This helps to relax the muscles inside the eye that are responsible for focusing, and keep your eyes from becoming tired out. Also, start practicing moving your eyes around while they are closed, to exercise your eye muscles.
Adjust Your Monitor Settings
An easy way to reduce eye strain is to adjust the settings on your computer monitor. Fix the brightness so it is about the same as the surroundings around you. Adjust the contrast to make reading easier (black print on a white back ground is optimal), and adjust the color temperature lower than the amount of blue light that the monitor is displaying.
