Greetings all) I registered here to share my experience, which may help some of you. First, I want to say thank you because your discussions helped me when I was desperately trying to figure out what was going on. I apologize in advance for the long text and for possible mistakes, I'm from Ukraine and English is not my first language. I bought a Legion5 15ACH6H (82JU00YKRA) Ryzen 7 5800H RTX 3070. The first day I used it for about 4 hours and noticed my eyes started hurting, but thought I was just tired or something. The next 5 days it got worse. My eyes hurt more and more until the pain became unbearable. My eyes were throbbing, my eyeballs hurt and I could feel a tear in the back of my right eye. I was already realizing that it was affecting the screen. I went to the store, where a seller told that this sensor is the best and can not be the cause of my problems( All this time I changed the brightness and contrast, checked the calibration and ClearType, blinks of course not on this matrix, the light is tiny at the top, which is difficult to notice(I'm not sure I'm using the right word. highlights - I mean bright spots that are visible on a dark screen). By all parameters, the screen is perfect, but the pain does not go away. I take a break for 1 day and my eyes come back to normal, and the next day I have a work order and I spend 8 hours in front of the screen. That's when the next day was hell. I couldn't sleep, couldn't even look at sunlight. My eyes had never been in so much pain, I had to go to the hospital, the doctor diagnosed irritation with inflammation, recommended limiting the use of the laptop and prescribed drops. The drops helped, as soon as my eyes were dry they eliminated it. Before that, I used a Lenovo Z580 with a TN matrix for 10 years and I worked at it for 10 hours a day. I was desperate. I had been saving up for a laptop for so long and what did I get. Other than the screen there is nothing to complain about, I liked the laptop more than anything. Another 5 days I doubted and tried to make friends with him(laptop), then I did not look at the screen directly, and constantly covered his hand and averted eyes. + bought computer glasses with protection (it did not help). In the end, I decide return the laptop and take Legion 5 Pro 16ACH6H (82JQ00XNRA) Stingray. I was just hoping for a miracle. When I got home the first thing I saw was horrible highlights( In all corners of the screen, and at the bottom right it was huge( I was not happy with that. 70,000 is a lot of money to me and I get a product like this. Still, I decided to give it a chance, but the eye pain manifested itself quickly and was the same + now I had a screen with highlights that annoyed me. I went back to the store and exchanged this laptop for my first one. It's like picking the best from the worst, at least there are no highlights. I ended up buying a VA matrix monitor and OH MIRROR. it worked!!! This monitor doesn't hurt me anymore. I also sit for 10 hours at it, but I'm comfortable, and the laptop works like a standard computer. If anyone needs to know this monitor - Samsung Odyssey G3 24". Guys, as I understand it, modern ips matrices have a powerful led backlight and not all eyes are able to adapt, especially if you have lived with a "faded" monitor for a long time before. My mom looks calmly at the laptop screen and does not feel any discomfort, but I am still in pain. It is probably a peculiarity of the eyes and the inability to adapt quickly to a bright, saturated screen. Try to buy monitors, look for the one that will not hurt your eyes and do not hesitate to return the product to the store if it did not fit (within the days that gives the law, in my country it is 14 days). Sorry for the long text and for possible mistakes in the text. Take care of yourself, your eyes and be healthy π
