I can sympathize with that. I too was feeling like there was something seriously wrong with my eyes, actually getting legitimately worried. I'm 35, and I've been using glasses since I was 15. Only last November I started to notice worsening symptoms, and this spring it got bad. Looking forward to a new monitor and prescription will do for me.I felt like I was going blind.
Aren't luminoodles also LED? How would that help? I used to have a LED strip behind the monitor for bias lighting and I can't say it helped anything...If you use led bulbs for room lighting ditch them and get incandesants pick up a luminoodle white bias light strip all the others are garbage as well.
The report (in French): https://www.anses.fr/en/node/139064Maisons-Alfort (France) (AFP)
The "blue light" in LED lighting can damage the eye's retina and disturb natural sleep rhythms, France's government-run health watchdog said this week.
New findings confirm earlier concerns that "exposure to an intense and powerful [LED] light is 'photo-toxic' and can lead to irreversible loss of retinal cells and diminished sharpness of vision," the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) warned in a statement.
The agency recommended in a 400-page report that the maximum limit for acute exposure be revised, even if such levels are rarely met in home or work environments.
The report distinguished between acute exposure of high-intensity LED light, and "chronic exposure" to lower intensity sources.
While less dangerous, even chronic exposure can "accelerate the ageing of retinal tissue, contributing to a decline in visual acuity and certain degenerative diseases such as age-related macular degeneration," the agency concluded.
Long-lasting, energy efficient and inexpensive, light-emitting diode (LED) technology has gobbled up half of the general lighting market in a decade, and will top 60 percent by the end of next year, according to industry projections.
LED uses only a fifth of the electricity needed for an incandescent bulb of comparable brightness.
The world's leading LED light-bulb makers are GE Lighting, Osram and Philips.
The basic technology for producing a white light combines a short wavelength LED such as blue or ultraviolet with a yellow phosphor coating. The whiter or "colder" the light, the greater the proportion of blue in the spectrum.
- Circadian rhythm -
LEDs are used for home and street lighting, as well as in offices and industry.
That are also increasingly found in auto headlights, torches (flashlights) and some toys.
LED cellphone, tablet and laptop screens do not pose a risk of eye damage because their luminosity is very low compared to other types of lighting, Francine Behar-Cohen, an ophthalmologist and head of the expert group that conducted the review, told journalists.
But these back-lit devices -- especially when they are used at night or in a dark setting -- can "disturb biological rhythms, and thus sleep patterns," the agency cautioned.
Because the crystalline lens in their eyes are not fully formed, children and adolescents are particularly susceptible to such disruptions, the ANSES reports noted.
Interfering with the body's circadian rhythm is also known to aggravate metabolic disorders such a diabetes, as well as cardiovascular disease and some forms of cancer, noted Dina Attia, a researcher and project manager at ANSES.
In addition, a stroboscopic affect in some LED lights -- provoked by tiny fluctuations in electric current -- can induce "headaches, visual fatigue and a higher risk of accidents," the report said.
For domestic lighting, ANSES recommended buying "warm white" LED lighting, limiting exposure to LED sources with a high concentration of blue light, and avoiding LED screens before bedtime.
ANSES also said that manufacturers should "limit the luminous intensity of vehicle headlights," some of which are too bright.
Finally, the agency cast doubt on the efficacy of some "anti-blue light" filters and sunglasses.

I don't need glasses, but I think it would be worth revisiting the eye doc for this issue specifically. Excuse my ignorance on all things glasses, but when you say 'transistional lenses' you mean lenses that change tint according to light conditions?Sorry to hear you're having problems again, partikl . Your eyes definitely can get damaged over years and you don't get that back. I've had the new Philips monitor for a few days and I've been very happy with it, I'll try to make a review soon. This week I finally got my new glasses - old prescription was .25 off so that wasn't really contributing to my eye problems. I got the new lenses with blue blocking coatings AND I made them transitional. My new ophthalmologist explained (and then I googled myself) that just 15 minutes of being outside does just as much harm as a whole day in front of your screen, so LEDs are not the only culprit: not wearing sunglasses is just as bad, as you're forcing all that blue light in your eyes and different people's retinas will decay at different speeds. Well, I'm beyond in love with these new glasses: everything has a very slight, nearly imperceptible warm tone to it, and my eyes are SO comfortable all day. I specially notice it at night, like now, when I'm using my computer and I have zero discomfort despite the monitor being the only bring thing in the room. It's seriously impressive. The transition coating is new to me, but already is making a huge difference - I barely notice it happening, I notice it when I realize if I look out of the frame and see it's so much brighter than what I'm seeing through glasses. Never looks "dark", just perfect. A few days with them, and my eyes are very noticeably more relaxed: no tension, pressure, strain, burning... nothing. If you keep having problems, blue light block + transitionals might help you too. In my case the blue light coating was included, the transitional was "only" $70 extra so I decided to try it - I might keep getting it in all my new glasses. So far, excellent.
I'll see if I can make a review of the Philips monitor tomorrow.
Exactly, transitionals get darker when in strong sunlight, go back to normal in interiors. It takes like 15 seconds for the full transition. I've never had them until now, but I'm noticing the benefit mainly in how "relaxed" my eyes are all day long. I'm told by friends I should keep noticing benefits for a couple weeks, until my eyes have fully relaxed after years of strain.I don't need glasses, but I think it would be worth revisiting the eye doc for this issue specifically. Excuse my ignorance on all things glasses, but when you say 'transistional lenses' you mean lenses that change tint according to light conditions?
Do you really believe light harms eyes?My new ophthalmologist explained (and then I googled myself) that just 15 minutes of being outside does just as much harm as a whole day in front of your screen, so LEDs are not the only culprit: not wearing sunglasses is just as bad, as you're forcing all that blue light in your eyes and different people's retinas will decay at different speeds.
It's not what I believe, it's what science proves. Talk to an ophthalmologist. I've had several give me similar explanations. I tend to trust science, paired with my own personal experiences.Do you really believe light harms eyes?
Science also says that sun light stimulates dopamine release in eyes and it is needed to maintain good eye-health and lack of proper stimulation is most likely the cause of rising eyesight issues in young people. This rings with me better than "wear sunglasses at all times when outside" which does not make any sense given my own experiences with sunlight improving eyesight.It's not what I believe, it's what science proves. Talk to an ophthalmologist. I've had several give me similar explanations. I tend to trust science, paired with my own personal experiences.
I did sun gazing and felt my eyes being literally burned... so I guess my eyes are truly different ◠‿◠Don't forget - your eyes are not like everyone's. Just because something is not problematic for you, it doesn't mean it isn't for millions of others.
Keywords from your post are: "proper stimulation" and "my own experiences". So, let me fix your statement: Fortunately YOUR eyes work the way YOU felt they do. That does not apply to all humans on Earth.Fortunately eyes work the way I felt they do and not how your ophthalmologist think eyes work. Besides what interest your eye doctor have in you seeing well? Sorry, I had to say this...
Please do as you please. Hopefully your doctors come up with something more to help you than putting even more glasses on you.Keywords from your post are: "proper stimulation" and "my own experiences". So, let me fix your statement: Fortunately YOUR eyes work the way YOU felt they do. That does not apply to all humans on Earth.
I'll take the opinion of well regarded doctors both in Europe and the USA over a random online forum commenter. Thanks
I am skeptical about this. Having monitor lower than eye line mean you always look down on it which doesn't sound all that healthy, especially considering record of eyesight of people who read books and use smartphones which are used in similar look-down configuration-Technically eye level should be at the top of your screen (not the center like you would for movies).
1) There is a difference between craning your neck down versus having things be below your horizontal view line. EG: I look across at a laptop monitor, even with the top of the screen being at eye level. Which also in the case of reading books and using cell phones as you put it helps drastically. You can't say that just because some people use bad body mechanics that therefore we all do.I am skeptical about this.

I just feel that position where heavier parts of eye fluid is allowed to move away from photosensitive cells in eye toward external part of the eye as unhealthy even if it might be more comfortable for both neck and even somewhat to eyes itself (though I find looking up just fine if not better). Not that it does as much difference with monitor position which is still in front as it does with eg. reading book that sits on a desk or using smartphone. I might just be taking my hunches about eyes and stuff way too seriously though =P3) Do as you please. I find it odd that I would list a dozen things to do, and you would take basically all of them as well and good (implied by not rejecting them), and then center in on one you claim is false. OP wants suggestions. I gave them. Do them or don't.
Ha, I'm now using this new Philips monitor at 0% brightness, and it's still bright enough for daytime use with 2 giant windows around my desk. %100 brightness is just eye-burning in this monitor, I could never use that. I wish I knew how much cdm/2 it's outputting. I use a spyder5express to calibrate, which doesn't tell me more information, kinda wish I had paid more for the next model up to get more information about color gamut, etc.I typically set my colorimeter to 100cdm/2. There are tons of people maxing out their brightness to 350-500+ and that to me is eye frying levels of bright, which for me causes my eyes to get tired waaaay faster.
You can use HCFR Colormeter (https://www.homecinema-fr.com/colorimetre-hcfr/hcfr-colormeter/) to measure your display.Ha, I'm now using this new Philips monitor at 0% brightness, and it's still bright enough for daytime use with 2 giant windows around my desk. %100 brightness is just eye-burning in this monitor, I could never use that.

Amazon and Power practical both have the Luminoodle dimmers in stock now they were out of stock for months picked up two because they sent me 7 sets to play with.If you use led bulbs for room lighting ditch them and get incandesants pick up a luminoodle white bias light strip all the others are garbage as well.
Don't buy the Luminoodle Dimmer switches lol I picked up two one of them shorted out on me.Amazon and Power practical both have the Luminoodle dimmers in stock now they were out of stock for months picked up two because they sent me 7 sets to play with.
Looking upwards means that the muscles are being strained, downwards they are resting.Small update: while I've been doing quite well with the new monitor, sometimes my eyes do get sore. I tried lowering the screen a few days ago, so it's now at desk-level and I'm lookin downwards at it. I've noticed a fair amount of improvement in viewing comfort - my eye fatigue is not completely gone, but it's certainly improved. Maybe something that some of you might want to try? I later read that apparently looking upwards lessens the eyes' tear production, while looking downward keeps the eyes more moist, so that might have to do with it. Either way, worth a try.
Is this the conensus here, that VA generally is the best for eye comfort and eye health when it comes to everyday usage and office productivity?It's been a couple of more weeks. Still no eye fatigue from a VA monitor. And I did end up staying with the 32UD60, despite the uniformity issue. Eye comfort is way more important to me. And after years of dealing with eye fatigue from monitors, no way I would go back to IPS or TN.
surely depends on the monitor, but most of the time I seem to like my contrast at about 70% and my brightness at about 30%If you lower brightness, should you also lower contrast? I find both affect perceived brightness. My screens can be quite right with 0 brightness and contrast cranked up.
So if you have eye strain with your current unit, I highly recommend buying one of these from Amazon, trying it out, and if it doesn't solve your issue, just send it back for a full refund. I asked about the eye strain from customers and got several replies with none citing any strain, and most saying its comfort level is excellent.Honestly surprised the heck out of me. I didn't expect this sharp of an image with a 1:1000 contrast ratio. Works flawlessly out of the box. The stand was pretty easy to setup. Contrary to what I've read, it DOES include an hdmi cable. The 75hz is just the cherry on top. I have never used a device with greater than a 60hz refresh rate, and was both pleased and surprised to find that that extra 15 frames had a noticeable difference. This honestly may convince me to upgrade to a 120hz or 144hz display later down the line. Overall, 10/10 would recommend.
und is better for the eyes I think. But it sure won't wi
So did you buy it and try it and report back? I don't see any followup unless I'm missing it in my searches.That said, I just found this Acer ED323QUR that has everything I want: VA, 32", QHD, curved, 144hz. It's not 4K, but that's a small concession to get everything else. I'll probably get this later this summer and will report back. Hope y'all keep posting about eye-strain issues, I've found this conversation enlightening and inclusive. We really all are affected by very different things!
I did not, but as you will see in the response I just wrote to your other thread on these forums (coincidentally before I read this response of yours), I’ve come to the conclusion over the past year that there are many more things to consider than just the panel, such as room lighting and window position. I just bought a Pixio Px275h because it has a dpi of 108 (which I have identified to be the right amount for my own eyesight to be comfortable, which I realized after using a 40 inch 4K TV as a monitor which had a GPA of 110), 95 Hz to minimize lower frame rate eye strain (I wasn’t willing to pay another hundred dollars just to go up to 144 Hz), and dci-p3 color gamut because I am pretty sensitive to color quality. I will receive the monitor next week and once I have used it for a little bit I will be sure to post a review on hardforum.So did you buy it and try it and report back? I don't see any followup unless I'm missing it in my searches.
