For most people, computer eye strain — eye discomfort, headache and vision problems from viewing digital screens for extended periods — is a fact of life.
Other symptoms of too much time spent staring at digital screens include eye twitching and red eyes.
The Vision Council has found that 59 percent of people who routinely use digital devices symptoms of computer eye strain (also called digital eye strain).
Thankfully, there is something you can do about it.
Here are 10 easy steps to make time in front of your digital screens more comfortable and reduce your risk of computer eye strain:
1. Get a comprehensive eye exam.
Having a routine comprehensive eye exam is the most important thing you can do to prevent or treat computer vision problems. If you haven't had an eye exam in over a year, consult an eye doctor near you.
During your exam, be sure to tell your doctor how often you use a computer at work and at home.
Also, measure how far your eyes are from your screen when you sit at your computer, and bring this measurement to your exam. Your eye doctor can then prescribe the best lenses for seeing clearly and comfortably at that distance.
2. Use proper lighting.
Digital eye strain can be caused by excessively bright light either from outdoor sunlight coming in through a window or from harsh interior lighting.
Reduce exterior light by closing window shades or blinds. Reduce interior lighting by using fewer light bulbs lower intensity bulbs and tubes. If possible, position your computer so windows are to your side, instead of being in front of or behind your screen.
If possible, avoid working under bright fluorescent lights. Instead use a floor or table lamp that provides softer, indirect lighting.
Generally, “soft white” LED light bulbs (color temperature: 2700 K) will be more comforting on your eyes than “daylight” or “cool white” bulbs with higher color temperature ratings.
3. Minimize glare.
Glare from light reflecting back from your screen or other surfaces in the room can contribute to computer eye strain. Install an anti-glare screen protector; and, if possible, paint bright or reflective walls a more soothing color with a matte finish.
If you wear glasses, purchase lenses with anti-reflective (AR) coating. AR coating reduces glare by minimizing the amount of light reflecting off the front and back surfaces of your eyeglass lenses.
4. Upgrade your display.
If you are working on an older computer, consider upgrading to a new device with the latest, high-resolution screen technology. Adjust the brightness of the screen to a comfortable level (about the same brightness as your surroundings).
Also, consider purchasing a device with a larger screen for easier viewing.
5. Adjust your computer display settings.
Adjusting the display settings of your computer can help reduce eye strain and fatigue. Generally, these adjustments are beneficial:
