Eye health in the electronic age

[Redaktion]

In the modern world, our eyes are constantly bombarded with information from displays. Whether it be from a laptop, smartphone, or some other device, many of us spend a significant portion of our day staring at some kind of display. As such, it is paramount that we should understand the strain placed on our vision and some steps we can take to improve and protect the health of our eyes.

It is very strange to see in suggestions HP EliteBook 840 G5 with PWM at ≤90% brightness.

Excellent article. These kinds are the best.

To add a few things,
1. Viewing distance also matters. It is generally advised to look at the screen from a distance of 40cm / 15inches or more.
2. Aftermarket, third party matte screen protectors are always an option for glossy displays.
3. Windows 10 comes with a blue light filter baked in, called "Night Light", easily accessible from Windows Actions panel by pressing the shortcut Win + A.
4. "Dark Reader" is a must have, lifesaving Google Chrome extension.
5. Using a laptop in a dark environment, the screen's lowest backlight brightness is just as important as its peak. The advisable level is below 15 nits.
6. Avoid PWM and TN altogether if possible. PWM also pertains to the laptops' keyboard backlight.
7. Refocusing part mentioned in the article is the most crucial. In fact, more essential than everything else combined.

Nice and necessary article even if i have noticed some discrepancies.

Darker rooms makes it much more difficult to refocus at other distances.
It forces you to be even more focused in the screen.
I have found that it is necessary that the environment should be with intensity similar to the laptop screen one.

They made it very clear in this article to avoid glossy screens at all cost.. Even making it one of the top causes of CVS.... then they praise the apple mac book even though it has a glossy screen????
Sorry, but that is just ridiculous!!

I 100% agree with their original recommendation to completely AVOID all glossy screens.

I had a glossy screen laptops for 9 years and it was terrible!

I now have a matte screen on my new Alienware 15 laptop and I never have to worry about reflections again. This is a vastly superior design no matter if it is TN, IPS, or something else. Glossy looks better on the showroom floor when you buy it. But if you are spending hours every day actually using it, then you really have to get rid of glossy screens. My eyes are still perfect, but that glossy reflection is just so annoying.

@me - They mention that PWM under 500 Hz is the main problem and the HP is over 3000 Hz. Might be why it still made the list?

As a person who has used PC's for decades and remember when resolutions were not even close to 720p let alone 4K. I think people today trading resolution increases for smaller screens may do more harm to eyes than they know. If you want more screen real estate use a bigger monitor. I am all for more pixels, but don't think that alone solves eye strain or gives you the ability to scale at levels that makes every font too small even if its possible to read it. That does not mean your eyes are any less strained. Given how much we spend looking at screens these days, its even more important to recognize that the easier it is for the eyes the better.
