Yeah I've seen some occasionally mention the "blue light" (aka HEV light, high-energy visible light) in this forum. So is there any consensus about it yet, or it is just not known yet because people have been using LED TVs, monitors and lights only relatively short time, and some effects might show only after decades (statistical)?

Trying to find information online, besides the Wikipedia link above, they seem to normally point to pages where a company is selling products which are supposed to protect you from it. I tend to take such product pages with a grain of salt.

I'm less concerned about the effect to sleep (I sleep fine, thank you), but more about the potential long-term effect on eyes. Using such amber glasses at work or in a Counterstrike tournament might look geeky, unless there is a real reason to do it. But that's fine, the few times I go to a concert, I always use ear plugs because I don't want to damage my hearing unnecessarily, even if it doesn't look cool either.

The little info that I've gathered understanding about the HEV light and their sources:

- In general, blocking HEV is trickier than UV (UV-A/B/C) because UV can be blocked 100% without affecting the image, while HEV is part of the visible light spectrum. That's why the "HEV glasses" seem to mention something like 97-99% HEV filter.

- Sun: Buy sunglasses which block not only UV-light, but most of HEV too. For shits and giggles, I asked in one local spectacle store, and they had no idea what I was talking about (HEV light filtering sunglasses?). :D

- LED TVs: Maybe not the biggest issue as people tend to watch them from greater distances? Just don't watch them too close.

- LED lights: Maybe not a big issue as long as you don't keep staring at them?

- Computer LED monitors and tablets: possibly the biggest issue (besides sun) as people tend to stare at them near for a long time.

So, wearing amber glasses, or just turning down the monitor brightness to lessen the risk, get the old CRT TVs and monitors back to use from the basement, or pffffffft doesn't concern me?

I don't care about wearing special glasses for monitor use. Then again, I need to wear prescription glasses to see just about anything at all, and getting another set for filtering is a bit too expensive for my taste (as for sun glasses, I have a set that's designed to go outside my normal glasses). I saw a lot of publicity for Gunnar Optics "gamer glasses" several years ago though.

I thought this was going to be about the recent NSFW games, but it's not.
I think I'll be fine. I will only be needing my eyes for a couple more decades, give or take. After that, who cares about long-term effects?
I bought myself some of those glasses here, since I game a lot and I work a lot on my computer, and I must say that I felt a real impact on my eyes tiredness. Is it really efficient on the long term, I don't know, but at least I can now spend a long time in front of my computer without having dry eyes...
The other day I saw something about how some researchers actually think antioxidants help cancer rather than fighting it like everyone claimed for years. Hardly the first time that kind of "oh wait" moment has occurred, either.

Screw all that alarmist noise. Everything is out to kill and/or harm everyone these days if the news and researchers are to be believed, so I'm going to die eating bacon and avoiding silly glasses.

So you bought one of those T'Aime optics glasses, or something similar? I have no idea how many companies are shipping such glasses, at least the spectacle stores here seem to have no such selection, only UV-blocking sunglasses and such.

How's the vision with them, ie. do they alter the colors on the monitor much or anything? I read that they have even a positive effect on the image, adding contrast and removing some hazy effect?

I should buy a new pair of sunglasses anyway (yes you need ones even in Finland, in the summer you know, plus whenever I go to Thailand), and that T'Aime page suggested they are good as sunglasses too (UV blockage etc.). Not too dark though, but maybe that is ok. Then I wouldn't feel I've wasted any money either way.

They seemed to be selling clip-on glasses too, for prescription glasses:

Naturally I wouldn't want to use $100 for something that is not necessary, so just trying to get some idea if there is any truth to this "blue light alarm". Yeah some people smoke too and never wear a safety belt, and they are doing fine...

Well, the Wikipedia article certainly make it seem like an unsubstantiated scare, and I would say that's likely to be true. Everything is bad for you in large quantities, and I'm sure that staring at a computer screen for hours certainly can have negative side effects. However, my guess is that the blue light issue is less of a health issue than many other issues of sitting all day in front of a computer.
Now we know how dangerous those dating sims on here are. I mean when you combine gaming and beating it like it owes you money...

Odd, I didn't get a similar view on the Wikipedia article. On one hand, it suggested it hasn't been proven to cause e.g. macular degeneration (which makes sense because one wouldn't be able to make such tests on humans, we haven't been using LED TVs and light bulbs for that long yet (=no statistical evidence), and overall the reasons for macular degeneration are not fully known but only suspected, and statistics will possibly give some indication at some point), but it also pointed to tests where the damage by HEV to retina was shown.

As for "sitting in front of computer is bad for health anyway", true, one can die in traffic even if one uses a safety belt or a helmet with a motorcycle. Anyway, I work with computers so I have to sit (or stand) in front of a monitor for longer periods of time anyway, in order to have money for food and GOG games.

Either way, I need to buy a new set of sunglasses anyway, so maybe I'll buy UV/HEV-filtering glasses this time. Whether I'll be using them with computers, let's see...

Same.

Well considering amber glasses and the like make me fucking ill I'm definitely not going to worry about it. I'm ridiculously light sensitive (even with heavy duty glasses sunlight and glare cause pain/discomfort), but have never had any issue with decent monitors and the like so I'd imagine the worry is really overblown. Considering the hobbies many people have that are really dangerous to eye-health this is sorta like worrying about a natural preservative being used in food while still eating MSG laced dishes.

Seriously, don't worry about these things. By the time you hit 40 your body will collapse on its own no matter what you do.
This is a load of marketing shit. As long as you have plenty of iron in your blood, you won't go blind from mere screens. Healthy dudes need not apply fullstop. If you're anemic like a stuck pig (8 g per deciliter -- why hello there!), you will go blind and UV/whatever blockers might help to mitigate further decay as you try to get your blood iron to quantities which don't make doctors suspect a vampire apocalypse under way. As it happens, I couldn't afford the glasses, but in five month I got my iron to a manageable 11. I still have the two initial black spots and nothing else.

Also, fucking with the visible spectrum can drive you nuts. Don't. (Sauce: personal experience.)

edit: and yes, I hoped it would be about HuniePop.

For the last 25 years I spent a lot of time in front of a display (a few hours every day). First it was a CRT, and for the last 10 years a LCD.

In the last 10 years I estimate I spent 10 hours daily using a LCD. I don`t have trouble sleeping and I still don`t need eyeglasses but you got me a little concerned. I thought LCDs are fine.

I don't think there's any need for it. Either change the colour temperature of the display (many give you that choice) or change the background of the software you use the most. For example my current background for Visual Studio is black, and that definitely doesn't have a strong blue component in it. :)
