PC screen, which brand to recommend?

It is virtually impossible to give realistically useful advice on this topic as it is very subjective. What may be suitable for John Doe is not always suitable for Jane Doe.
Things I would look at are what sort of applications will you most often use, word processing/ spreadsheets/ graphics editors/ games etc.
Is it more important to you that a screen renders text sharper than it renders graphics? Does colour representation matter to you, does the display have colour profiles available if so.
What native resolution are you looking for.
Do you wear contacts/glasses, for long sight/ near sight. How long will you be staring at the screen. What is the environment like where you will be using the screen.
What is your budget.
Honestly the variables are extensive and only you know what your requirements are based on your usage, environment and preferences.
Maybe some more detail would enable someone to point you in the right direction.

Ok, so have you considered a TV with HDMI input, would probably be cheaper for a larger screen size (physically, not talking resolution) as long as your PC has HDMI output.
I currently use a Hitachi 42" HD (1920 x 1080p) TV, it has a 60hz refresh rate (important to avoid flicker), several built in picture modes for film, sport, games etc and all the usual settings for quality, trueblack and so on.
Some TV's (like mine) even have dedicated PC inputs (VGA, DVI, Displayport).
Its just an idea, plus you can always go into a TV shop and see the picture quality, size etc in use, cant really do that with monitors.
With TV's now sporting 4K resolutions (8K on the horizon), HD TV's are cheaper than ever.
Where monitors have the edge is in true high refresh rates, most modern TV's in general are 60hz base, maybe enhanced to 120hz, whereas monitors can have true 120hz upwards (144hz being common now) ideal for gamers chasing high fps, but really not needed for video, word processing and web browsing.

Which brand is best for eyesight? what parameter to pay attention to when purchasing a PC screen?

Go with a Dell Ultrasharp 27-inch. Great quality. It's a bit expensive but you will enjoy it immensely.

I have two of these, price it around...

You probably don't need 4K capability, but contact them for assistance on this and compatibility with the video that you will be using.

Many ways to tweak it for your eyes, but W10 has much to do with it. Takes a bit of time to get it "just right."

Strictly, IMHO.

Brands are one thing, but the panel you're actually looking at is most important. Asus, Dell, Acer etc can all have bad panels - or unfitted panels for your eyes - on certain monitor products. So before you buy one from a "good" brand, make sure to look up the panel being used here: DisplaySpecifications - Specifications and features of desktop monitors and TVs

If you have sensitive eyes you should stay away from FRC panels.

FRC is a form of temporal dithering which cycles between different color shades with each new frame to simulate an intermediate shade. This can create a potentially noticeable 30 Hz flicker. FRC tends to be most noticeable in darker tones, while dithering appears to make the individual pixels of the LCD visible

Go with high resolutions, true 8 or 10bit panels on IPS for good color depth and crisp texts. I can also recommend the Dell UltraSharp U2719D by @Compumind. Here are its stats: 27" Dell UltraSharp U2719D - Specifications.

I made a list for you to prioritize when looking after a monitor based on your needs:

• High resolution (crisp texts and better pixel density for reading)
• Eye care technologies (flicker-free, low blue light, brightness options to avoid eye strains)
• IPS Panel (For color depth and better viewing angels)
• No FRC (True 8bit or 10bit panel to avoid temporal dithering in shades)

Panel types: For movies and videos, VA panels have better contrast ratio and blacks than IPS, but worse color reproduction and response time. IPS is good for almost anything, especially in day-to-day use, but lacks in response time compared to TN. I don't recommend TN panels for you as the majority run in 6bit+frc, and they're mostly used for its good low input and GTG response time in gaming usage.

Yes, like @Faith said, TN and FRC Panels are basically inferior.

Go for the UltraSharp U2719D - you won't be sorry.
