Computer Glasses: COMFORTABLE Vision In Front Of Screens
Why Do We Need Computer Glasses?
With so much of our work being computer-based, the demands on our eyes can reveal issues we didn't know about. Staring at a screen for a long period of time can cause symptoms like blurred vision, tired, red eyes and even headaches. Collectively these symptoms are known as computer vision syndrome (CVS) or digital eye strain.
It is estimated that anywhere between 75 to 90 percent of computer users suffer from digital eye strain. A few simple steps can help your eyes cope with their daily workload. One step is choosing the right lenses to reduce digital eye strain.
What Happens to Your Eyes In Front Of Screens?
Since the 1980's it's been shown that using a screen is different to looking at text on paper. In 2017, a study at the University of New South Wales found that in just one hour of mobile phone use, the level of symptoms reported by the users increased dramatically. Another study found that when looking at screens our point of attention, (where our eyes converge to), moves further away the longer we look. It’s estimated that people spend on average around seven hours behind screens daily, so it's no surprise that we start to experience:
Are there Solutions to Digital Eye Strain?
The obvious answer is to reduce our screen time, but that’s simply not possible for most people. Between our jobs which often involve working on computers and the increasing use of smartphones, we’re not putting our screens down anytime soon.
Fortunately, there’s new lens technology to help relax our eyes when we use our digital devices, like Eyezen. Combined with the measures outlined at the end of this article, your eyes can feel better about living in the digital age.
How To Reduce Eye Strain
Eye strain occurs in other situation than using screens. In fact, prolonged periods of reading or other concentrated close tasks can result in tired eyes, redness, dryness, headaches and neck and back pain. Here are some tips to help reduce these problems:
- Check your lighting - eye strain can be caused by bright office lighting or light coming in through windows. Close blinds where possible and turn your computer so windows are to the side instead of in front or behind the screen. Overhead fluorescent lights can cause challenges to the eyes for many office workers, halogen or indirect incandescent lamps may be easier on the eye.
- Set up your desk properly - your screen should be about 50 to 75cms away from your face, or about arm's length. The menu bar should be at your eye level. You should be able to sit back comfortably with your feet flat on the floor with your knees at right angles and your ears, shoulders and elbows should be in a line.
- Adjust your display settings - The brightness of your screen should be around the same brightness level as your surroundings. Ensure the text is at a comfortable size when reading, so be sure to zoom in to avoid straining.
- Eye exercises - blink regularly (to help stop dry eyes), take regular breaks and remember to practice the 20-20-20 rule. look away from your screen every 20 minutes for at least 20 seconds and turn your gaze towards something about 20m away (e.g. out of a window if possible)
- Look after your eyes - it's important to have regular eye tests to ensure you're getting the best vision possible.
