Hello everyone,i wanted to share a story about what happend to my vision and i'm, 99% sure that BenQ monitor's cause it but i need to warn you that it might be long read a bit and please forgive me if i made any speling mistakes english is not my main language but i hope you will understand what i want to tell. Ok lets begin. In 2012. i got my first PC from my parents,it was an old PC with Belinea 1705s 17" CCFL TN monitor. I've been upgrading PC often since then but i didn't changed monitor until 2016. For those 4 year of usage i've been having eyestrain,dry eyes and red eyes but nothing serious and it wasn't bothering me that much and it only happend when i've been using PC for like 12 hours or more. What was important to me was to keep my vision good because i had perfect vision i never worn glasses or lenses and i was scared that this monitor could damage my vision because it was old. I then decided i need to buy new monitor and keep my eyes healthy so i ordered BenQ GW2255 VA LED monitor with flicker free technology. When i got that monitor after just a couple minutes of usage i noticed immediately something was wrong,LED light from the monitor was somehow pinching my eyes it was a weird feeling but i tought maybe i just need to get used to it. I continued to use that monitor and because i didn't work anything back than i was playing games all day long. After few months problems have started,first thing i noticed was when i was watching a movie in the dark room with black background and with white letters i could see double it was ghosting. I didn't got scared and i thought maybe it's normal.I continued to use PC normally and i noticed it's getting worse. In the summer off 2017. i started to work at nights driving a taxi. Then the nightmare begin it was the time when i finally realised how much my vison was damaged,it was terrible i had ghosting,starbursting,halos and glare problems but i still could see sharp at distance and close. In the daytime i still have perfect vision but in the night it's terrible. I got really scared and went to ophthalmologist. He did't found anything,my eyes are healthy and i don't need glasses. Then i decided to buy new monitor and get rid off this one and bought brand new BenQ GW2406Z IPS LED Low Blue Light Flicker Free monitor. It didn't help at all it was worse than the other one,i can not stand to watch at it long like i was able to watch in the prevous one or the old Belinea. Since than i went to 4 more ophthalmologist and nothing. I still drive at nights and it's still terrible and it got worse over time but it only get worse when i use that monitor and i have a solid proof. Here it is....about a month ago a had ingrow toenail surgery and i had to be in bed for 5 days for recovery,i coudn't walk so i decided to use my PC for those 5 days,i though what is the worse thing that can happen for only 5 days? I've been playing games and watching movies for those 5 days on GW2406Z and after 5 days when i was recovered i decided to go out at night. I didn't noticed that my vision had changed in the lit room only thing was that my eyes were dry and a bit red but i tought it's normal i had that even with my old Belinea.When i got out i almost had a heart attack,my vision went from bad to terrible,every starbusting and ghosting was 3 times bigger it was a disaster. I got so scared almost started crying. Went to do home to find artificial tears because my eyes were dry and it didn't help at all. Since than my vision hasn't improve at all,dryness disappeard the next morning but my vision never return to what it was before those 5 days. I still drive at night but it's a nightmare now really,i didn't use GW2406z at all since than i only use my old Belinea monitor. Conclusion,i think that those two monitor ruined my eyes (and my life two because i'm 22 years old and i always had only one wish in my life and it is to become truck driver but with vision like this i don't think i will be able to). Also i need to mention that i used BenQ monitors on 0 brightness and they don't flicker i tested it. I hope that someone will read this and maybe figure out how dangerous monitors can be,i'am now really depressed every day when i wake up i have only one wish to somehow fix this issue and return everything to normal,i don't go out anymore at night and i don't play games and i was able to do both before i bought BenQ monitor. I wish that i stayed with my good old Belinea and never bought new monitor things would be so much different now.
