- The side effects of computer screens
How many of us are staring at computer screens right now? We do it day in, day out. It’s a job requirement, whether we work at home or in an office, that we’re looking at computer monitors on a daily basis. And even though we might believe there is no way technology could possibly be doing any harm to our eyesight – there’s a good chance that’s not true. So what damage does staring at a screen do to your eyes over time? Let’s take a closer look...
There’s little denying just how much of an impact modern technologies have had on all aspects of our lives.
- LCD screens: The difference between good and bad ones
Not all screens are created equal. Modern-day screens range from in-plane switching (IPS) to vertical alignment (VA). Which type is best for your needs and how can you tell which is which? Read on to find out. To make a long story short, both VA and IPS displays offer great color accuracy, but IPS monitors tend to be better for general use because they're brighter, more color accurate at wider viewing angles, consume less power, and usually cost less than their VA counterparts. However,
both types of screens suffer from bad gamma performance out of the box; a feature that's built into Windows 10 allows users to fix it by adjusting monitor settings. But with these two types of displays dominating sales charts these days—VA becoming increasingly popular.
- How to avoid damage from computer screens
If you work in front of a computer screen, make sure to take frequent breaks from looking at it. The blue light emitted from computer screens is bad for your eyes, and can cause headaches. Worse yet, too much exposure to blue light makes your eyes more sensitive to UV light—and that could spell trouble if you spend time outdoors (or under fluorescent lights) right after staring at a screen. To protect yourself: Take a break every 20 minutes or so; look away from your screen while taking stock of what’s left to do; close your eyes and rest them for ten seconds; find an alternative source of bright light (like a lamp) to look at. Look up programs that reduce eyestrain and eye strain on Google or Bing search engines.
- These side effects can be prevented with glasses
A pair of glasses is not a cure-all for all ills, but they can protect your eyes from digital eye strain. It’s best to wear glasses as you would prescription sunglasses: outside, for a limited amount of time. Those who are myopic should always wear their glasses when in front of computer screens—but if you don’t have them on hand, it’s still important to take frequent breaks from computer use. Also, be sure that your monitor is at eye level and roughly 20 inches away from you at all times.
