Question Is it true that monitors are without filters and spoil eyesight?

[kacper6768]

I'm using an LG W1943(Analog) monitor with the maximum supported resolution of 1280x1024 and I'm thinking of replacing it with another hardware. After a few hours of using this minitor, the icons and letters become double, but only when the monitor is working continuously for several hours, but when the monitor rests for an hour, the letters and icons are sharp again. From what I've read, some lamps in the monitor are damaged. Is it true that even the modern LED and Oled monitors are without built-in filters, even though they would be very cheap to assemble them in the factory and that they spoil the eyesight, but every monitor after a long time of use spoils the eyesight, but if they had filters, they would allegedly spoil less. I don't want to bring up conspiracy theories here but that's what this doctor Jaśkowski said that normally technology would develop in such a way that instead of monitors, projectors would develop that would show the image on the wall, it would be less damaging to the eyesight because one's would look indirectly at the wall instead of directly at the monitor and that's why for ophthalmologists and pharmaceutical companies to make money. I don't know if it's true, I'm just repeating what I heard and I'm curious what you think about it? I apologize in advance if it is against the rules of this forum to discuss conspiracy theories. This is what some doctors on YouTube, for example Jerzy Jaśkowski, said. I don't know English well, that's why I only watch Polish YouTubers. Me from a distance, when I see rear red car lights or other black light bulbs, I see quite sharply the brightest red color but the worst blue color when, for example, I see blue light bulbs from the same distance, for example, those on a police car, these are such big blurred blue balls but sharply I can see red light bulbs even when viewed from a much greater distance than this dim blue light. The monitor emits blue light. If I never used a monitor or TV, would I be able to see blue light bulbs clearly from any distance?

I presume this is related to the issue with the whole blue-light scare a few years ago: https://en.wikipedia.org/wiki/Biological_effects_of_high-energy_visible_light . However, a lot of research pointed out that there's no real link between long term exposure to blue light and damage to your eyes. I mean, there's this thing called the Sun that emits blue light every time its out, and the sky scatters blue light which is why it appears blue. So basically, you're constantly bombarded with blue light and people well into their 100s can see just fine (well, for someone their age anyway).

The only real health concern that was definitely linked to blue light exposure was the disruption of the circadian rhythm, i.e., your sleep cycle. If only because your mind thinks "blue light = blue sky = day time"

If you're concerned about eye damage or eye care, this is what you should do instead:

• Adjust the monitor settings and lighting in the room so that the screen is comfortable to look at.
  • Regarding something like color schemes (e.g., dark mode or light mode), it's actually more of a preference thing. However, there's some suggestion that light mode may be easier on the eyes for reading text because dark mode causes the pupils to dilate, which makes it harder to focus on things. And that may cause straining.
• Take regular breaks from looking at the screen. A rule of thumb is to look at something else every 20 minutes for 20 seconds that's about 20 feet (or 6m) away.
• Use eye drops if necessary
