I just tried the kindle fire HDX 7 tablet with quantum dots. This new technology is amazing and the best color reproduction I've ever seen. I still had some eye strain with this tablet, but did not really spend enough time with it to be 100% certain if I could use this for many hours a day. I didn't purchase it because I prefer iOS at this point. There is some speculation that Apple is going to be using this technology in the future, and while I'm very interested in that from a color accuracy standpoint, I'm still not convinced that the eye strain problem can be corrected by using a more complete spectrum without blue shift. If that were the only solution, I imagine that OLED and the sony triluminos quantum dot displays would be a complete fix to this situation. That said, the more iterations of different screen techologies the better as I hope eventually one will come out by "accident" that works for us.
I also have very bad eye strain from monitors and screens. As many of you i also can't use led technology. This all start after a lasik surgery. In the last 5 months i have bought 6 laptops and 5 monitors. I had to return all laptops including a macbook pro because the eye strain was very bad. The best monitor i have tried was a dell u1708fp but still far from perfect. I also bought a dell u2410h that was better than all the led monitors, but still very bad for my eyes. I can use all day an old laptop screen from 2008 with lcd ccfl backlight. What im going to do is to buy a controller that will allow me to use this laptop monitor as an external monitor.
Im trying to find a solution for my eyes. Im searching for monitor filters. Unfortunately i believe there is nothing in the market for us, and we have to create our own product. I found some filters that i think its worth to try.
-Quality window film tint as llumar or 3M
-llumar air 80
-Ambert uv blocking film (This one looks really good)
In my opinion the best way to use this films is to buy 1mm (or thinner) clear acrylic sheet and then glue the film. If you glue it directly to screen it will be very difficult to remove without damaging the screen. Any of you have tried window film as a screen filter?
I know that sometimes we talk about sensitivity on other devices, such as the iPhone, and I want to report that I just upgraded to IOS 7.1 on the iPhone 4S (can't use the 5), and I noticed a difference immediately. I was not expecting it, so this is not a psychological effect. I immediately looked to see if my bright settings had been adjusted because, as illogical as it seems, this made a difference to me on the 4S. Not perfect but better. The setting was the same. After looking at the screen for just a few moments, I noticed a dry feeling in the eyes and a strain on my eyes. I have to be honest, I thought I had experienced a spontaneous improvement since I could use the iPhone 4s with no problem. Didn't understand it, was just glad to be able to have an iPhone. Wish I had not gone to this upgrade. Only time will tell if I adjust or have to abandon the phone. It definitely hurts my eyes. It has to be the software because the hardware did not change. If anyone has any advice, I'm open. For any of you able to use the iPhone with the previous OS, take care in upgrading. You know Apple won't let you revert.
I have purchased Benq 2405 in order to test it. I have been playing with it for the last 3-4 hours. The display is supposed to be flicker free and has a functionality to block blue light.
Up to now i think for me is the best led display i have used. I guess it is not as perfect as my old ccfl displays, but i think it could be a display i could keep.
The only symptom i got was that after a couple of hours of continued use i felt a bit dizzy, but that was it. After 15 minutes of rest i was fine again. No eye strain, no headaches. It maybe that i have not being used to work with large displays, up to today i had worked with up to 19".
I have attached the monitor to my professional desktop pc HP / Win7 / Intel HD Graphics. I keep the blue light functionality to office mode 60% which is for me a good brightness level.
One strange thing is that while the letters in ms office apps and Windows menus are very crisp, in the internet explorer and chrome the letters are a bit blurry.
I will post again tomorrow after i spend the day with it and see how i will be tomorrow morning in terms of sore eyes and headaches (if any).
After a full day of work with Benq 2405, i can say that it is the best led display i have used up to now. Yet it is not as comfortable as my ccfl displays. While i don't get severe eye strain, I get a persistent mild dizziness, a symptom i am not getting from the ccfl displays i am using. Today i woke up with this dizziness, which i don't know if it is something that i should ignore and if i will be able to get accustomed to it in the future. So I am thinking whether i should keep it or send it back.
I think this display is an improvement, considering the history of led displays and the symptoms they cause to a minority of the population, but i think it does not provide the comfort of a good ccfl display.
Those new iOS 7.1 settings didn't help me. I tried several combinations and (low) brightness settings, too. My iPad 4 still hurts my eyes, it's incredible. After like 10 minutes I was forced to turn it off. Half an hour later now, still sore eyes. Everything was good with iOS 6 for over 1 year (I used the iPad many hours a day without pain). The difference is like night and day. It would be helpful if an Apple engineer would talk to us so they can identify and fix the problem.
I wish Apple believed this is a problem. Our complaints and comments fall on deaf ears. The settings are not a perfect fix, for sure. I can't use an iPad at all, regardless of setting or IOS. This only allows me to use my iPhone a little. I still get eye strain and the subsequent fatigue. I had no problems with IOS 6 or iOS 7.0.6.
However, 7.1 is definitely a problem. Sorry this didn't help you at all.
I am also one of the LED sufferers. I can only use XP on a CRT. I am trying to get comfortable with Windows 7 on a CRT as I have problems with CCFL and LED monitors. CCFL gives me a pain in the temples that goes away after an hour or so. If I use an LED monitor. I get different pains depending on whether the issue is Flickering or Blue light. Usually Flickering hits me first. I have tried all kinds of monitors with no good results. I have tried the Sony VAIO with no joy and recently I got a BENQ BL2410PT. I put the blue light down by 75% and brightness at 50%. I was on the monitor for about an hour and it seemed ok. But later that nite I developed a pounding headache in my temples and it is still there 3 days later with a huge sensitivity to light. So it is back to CRT for me.
For Windows 7 on the newer laptops I just have a hard time looking at the screen for any length of time. I had been using a Lenovo X220 connected to a CRT but it looked fuzzy with True type turned off. I have a number of X200 Lenovos and they are clearer but still difficult to look at. I have also gotten a USB to VGA adapter and that seems to make the Lenovo X220 clearer but I have to try that for a length of time. I am also trying out blue blocking amber film from lowbluelights.com
So for me flickering is a big issue and how much blue light the monitor puts out is another factor. LED monitors literally burn my eyes. CCFL don't go so far into the blue of the sprectrum so I have a little more tolerance for them.
What I would like help with now is suggestions on how to get Windows 7 working on a CRT comfortably. Any hacks or suggestions would be useful. I will have to wait for a monitor technology that doesn't have spikes in the blue end of the light spectrum
It seems like a fair few people are using Windows XP here with no trouble, myself included. Presumably Windows 7 is no good.
Does anyone have experience with Vista? I recall reading that if you turn the Aero effects off then it is fine.
The reason I ask is that Microsoft is about to withdraw support for XP, which means we'll no longer be able to get updates for programmes on there. Some programmes may even stop working.
Also, I may be late on this, but Ebay has some decent spec refurbished computers with XP on them for decent prices. I've just ordered one to give it a try, but it occurred to me afterwards maybe I should have gone for Vista.
At least for me the OS doesn't seem to make a difference. The new LED HP monitors at my hospital kill my eyes rapidly regardless of win7 vs. xp. I'm OK on any OS I've tried with a CCFL or CRT. I can power through ~ 4 hours on the MacBook Pro retina, but I will have eye pain lasting ~ 2 days afterward. I no longer get nausea but definately will get a headache. My hope for now is some new display tech using quantum dots. I was hoping transflective tech like mirasol or liquavista would lead to a new type of display, but it seems that LED backlit displays will be the main technology for the forseeable future.
I was using a WinXP desktop computer with an LED monitor last week at one of my clients' offices. I was able to force myself to use it for an hour which was better than my Macbook, but it was still unconfortable and I couldn't use it for longer.
While LED screens are part of the problem, for me there is definitely something in modern operating systems or graphics cards as well, as I can't use my Macbook through a CCFL display. There is also the issue people have been reporting with IOS 7.1, where a software update has made it unusable.
I'd be interested to know if anyone can use a Win7 desktop computer through a CCFL monitor but has had problems with other operating systems
