Everyone stares at the computer or phone screens these days. And it’s causing a serious eye problem called digital eye strain in a large number of people. Recent research showed that 59% of the people who use computers and other digital devices on a daily basis experience symptoms of eye strain. It’s also called computer vision syndrome or computer eye strain. Symptoms of computer vision syndrome include eye discomfort and fatigue, headaches, dry eyes, red eyes, eye twitching, blurred vision, and neck or shoulder pain. Here are some good ways to reduce the risk of eye strain and symptoms of computer vision syndrome (CVS).
1. Use Proper Lighting:
Eye strain is often caused by extremely bright light either from harsh interior lighting or from outdoor sunlight coming in through a window. While using a computer, your indoor lighting should be about half as bright as that typically seen in most offices. Eliminate exterior light from coming in by closing blinds, shades or drapes. Interior lighting by using lower intensity bulbs or fewer bulbs. Many computer users feel vision comfortability if there they turn off overhead fluorescent lights. If you are bothered by overhead lighting, you can opt for floor lamps that provide ‘soft white’ LED lighting.
2. Adjust Your Computer’s Display Settings:
Adjusting the display settings of your computer rightly also contributes to reducing eye strain and fatigue. Adjust the brightness of the display screen so that it’s approximately the same as the brightness of your surroundings. Also, adjust the text size and contrast of screen for eye comfort, especially when composing or reading a lengthy document. The best combination for comfort is black words on a white background. Moreover, color temperature refers to the spectrum of visible light emitted by your color display. Blue light has short-wavelength, which causes more eye strain than longer wavelength hues such as red and orange. Reduce the color temperature of your display screen to reduce the amount of blue light emitted.
3. Blink More Often:
Blinking is essential when working at a computer. Blinking helps moisten your eyes to prevent irritation and dryness. So blink more frequently while staring at a computer or mobile screen. Try to blink your eyes with complete lid closures. Dry eyes can be caused by evaporation of tears during the non-blinking phases. To prevent dry eyes during computer use, slowly blink your eyes ten times every 20 minutes to rewet your eyes.
4. Consider Computer Glasses:
You can consider having customized computer glasses or upgrade your existing eyeglasses to the ones with blue light protection. Photochromic or lightly tinted lenses are filtering computer eyewear that helps protect your eyes from potentially harmful blue light. These non-prescription lenses block some of those harmful rays. They are significantly useful to reduce eye strain. It’s also essential to get your eyes checked at a LASIK surgery center if you feel the continuous eye strain.
5. Minimize Glare:
Glare from light reflecting off finished surfaces and reflections on your computer screen can also lead to digital eye strain. You can mount an anti-glare screen on your computer display. Consider painting bright walls a darker color with a matte finish. Also, purchase glasses that have lenses with anti-reflective coating. Anti-reflective coating reduces the amount of light reflecting off the front and back of your eyeglass, which in turn reduces glare.
