Because most of us spend several hours each day looking at a computer screen, we often just assume that we have to put up with some degree of eye strain. We may experience eye fatigue, headaches or burning eyes – often referred to as computer vision syndrome or CVS – when looking at our monitor for long periods of time.
In this blog we look at the common causes of computer-use eye strain, and what we can do to avoid it.
What causes eye problems or eye strain related to computer use?
There are many reasons why we experience eye strain or other types of CVS when using computers, but the most common ones are:
- Monitors are usually too bright for our eyes
- The colour temperatures in most monitors are set to colder tones
- Some monitors have pixel inversion issues and, as a result, the screen does not
alternate between positive and negative voltage fast enough to remain invisible to the naked eye; when used regularly for a long time, the visible flicker causes eye strain
- The pixel pitch of your monitor (the number of pixels used to make up an image on
your screen) is not adapted for your eyesight; a larger pixel pitch will significantly reduce strain on your eyes
- The monitor has a poor backlight which may cause your eyes to ache after long
periods of continuous viewing
Sometimes the solution is just a matter of adjusting settings through your control panel. For some of the other causes, however, you may need to get us to have a look at your set-up.
How do you choose the best monitor for your eyes?
We’ve put together a list of the top 7 things to keep in mind when choosing a monitor:
- Choose a monitor that provides bright image quality with efficient text and icon clarity
- IPS (in-plane switching) monitors are thought to be better than regular monitors because of their consistent and clear presentation of colours
- If you cannot afford an IPS panel monitor, a VA (Vertical Alignment) panel is your best alternative. It will give you almost all of the same attributes that are present in an IPS panel, at a much lower price
- Look for a monitor that uses blue light technology and is TUV certified flicker free
- Make sure your monitor has ergonomic options that enable you to swivel, tilt and pivot it for optimum comfort
- Choose an antiglare monitor, which is much better for your eyes than a glossy monitor
- Use a monitor with a screen resolution of 1080p, 1440p, or 4K. If you want a smaller screen size (22” to 24”) go for 1080p screen resolution. For medium screen sizes (24” to 27”) choose a 1440p resolution monitor. For large screen sizes (27” and above), a 4K monitor works best when it comes to keeping your eyes safe
