Haha ok mate, enjoy your pimax then and thanks for warning us here.
The flashing you see from time to time is part if the demister/defogger system.
If shutter glasses are used to reduce ghosting, wouldn’t it be possible to reduce ghosting further by altering the shutter timing? They could shut longer, the reduced brightness could be compensated by just setting the screen brighter. The ghosting drives me crazy. Ok, that’s the opposite of the toppic, sorry
Yes, exacly @grzvs, i remember the same thing. When I removed the lenses the flashes are over.
You are right, but there is a crazy guy here who spend his time to throw bullshit.
I posted here a link to french medecin website where a doctor explained the studies made and how this light impacts and damages your retina and this crazy asshole said that it was bullshit.
1_ there is no shutter glass, it’s a piece of plastic with 2 electrodes. Pimax never said that they used a shutter glass, they confirm that they used electrodes for their anti fog system, that’s the vertical lines that you can see from times to times.
It’s a plastic filter with an anti fog system, that’s all.
By the way reducing the blue light (color) will have no effect to the blue light that will damage your retina. it’s not the same light at all.The light which will kill your retina comes from the backlight of the lcd and has a different wave length.
My anti blue light glasses have a yellow tint.
1.) It is not plaatic it is Shudder glass & does have the anti fogger. Without the shudder glass the panel is very bright (to compensate for the effect of shudder glass dimming panel) The shudder glass is tye customizeld low persistance implementation.
2.) Reducing the blue light part of the spectrum (notbto be confused withbtge color blue) can & is done in hardware software. Many cell phones have implemented soft adjustments (Turn cool colors off in piplay).
3.) The yellow tint on your anti blue light glasses has nothing to do with blue light reduction. The blue light reduction -is- clear. The yellow tint is for improving display in areas like contrast.
The above pic is from gaming glasses. The study you mentioned is theorectically causes damage. Now ensure your wearing those glasses at all times if your overly concerned as Sunlight/light bulbs & tubes also emit blue light. Yes over exposure of blue light may cause degeneration in the eyes. However that should mean folks who work staring at lcd computer monitors would all require glasses & we know crts were alot harder on the eyes.
As for spreading non sense wasn’t it you who thought 1440p input was not possible in steam or oculus? That you could only get get thatvin piplay titles?
Correct. His name is gp20.
LOL. If I remember correclty your article said that extreme levels of blue light damages ANIMAL eye cells (way different than human eye cells: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3144654/). Even if it were true, it has nothing to do with the amount of light coming from a monitor:
"The idea that looking at screens causes permanent damage is a big claim, one that should be backed up by evidence in the form of scientific studies. But studies showing that screens cause this kind of harm do not exist.
It’s not that light, or blue light specifically, is harmless, it certainly can be. But for now, there is no research showing that these devices expose us to enough light to cause any damage. Doctors do have explanations for why our eyes feel tired and stressed after looking at screens, but those explanations don’t necessarily include light at all."
And from that same article ““People are very worried that we’re looking at our screens more than we ever did,” says Dr. Rahul Khurana, clinical spokesman for the American Academy of Ophthalmologists. “Everyone is very concerned that it may be causing damage to the eye, and it’s a valid concern, but there’s no evidence it may be causing any irreversible damage.””
Exactly. Also my monitor comes with that option. If you look at the source code of the Galaxy 8 phones you will also see that the ‘blue light filter’ is nothing more than just less blue colour to the screen. It’s the same with piplay (‘cool colours’ set to off, that’s the real pimax way of diminishing bluelight, I’ve also confirmed in the firmware code that it’s just a display panel setting and NOT related to the shutterglass). And gp20 clearly doesn’t understand the Pimax low persistence implementation in the Pimax 4k. Maybe if he’d remove the shutterglass he’d see himself how blurring increases, but he’s too scared to burn his eye cells. He’d rather have 10x more bluelight fired at him if he’s behind the ‘safety’ of the shutterglass, although experts agree that that might not be a good protection at all, also see that article I just posted. I honestly think just lower brightness is a way better way of protecting your eyes (like I’ve accomplished with my modded FW, which I posted above). If I’m afraid of skin cancer I’d rather avoid the sun than go into the sun with a high sunscreen factor on my skin. It’s always better to just avoid it instead of relying on some filter. Also remember that it’s not bluelight alone that’s possibly bad, it’s the WHOLE spectrum. It’s just that bluelight is the worst of the spectrum, but it really just depends on the brightness. Red at high brightness may be way worse than blue at low brightness.
the blue light filters are actually like ND filters used in photography. they would go onto the lense and u twist them and they get darker and darker untill u have the right setting. if you hold your pimax filter infront of a lcd and twist it u will see the same.
i did some testing and found the difference in colour was very small however turning the filter a tiny bit makes it alot darker. im not sure as i didnt open my headset for months but does the filter have a set position or can it be adjusted slightly. maybe when they are in they are slightly activated and need to be rotated to the left a fraction.
The dark lens in this case is not a blue light filter but shudder glass. The blue light protection is software based.
The dark lenses are shudder glass used forvlow persistance implementation.
There is no blue light software efficient for one raison, the blue light which damage your retina comes from the led backlight.
You remember wrong as always. By the way the website was french.
It talks about effects of light with a wave length between 415-455 nanometer on retina cell.
Of course you know more than doctors and specialists.
Ophthalmologists for decades have warned about televisions and computer monitors
cause damage to the retina (fluorescent lamp = UV radiation).
That guy, “sjefdekjerk”, was the reason I stopped coming here. Now I enter to see if it came out new PiPLay.
He is very toxic, self-centered, arrogant, he knows everything, even when he has no idea what he is talking about.
My suggestion remains the same for everyone, even for “sjefdekjerk”:
Do not increase the amount of radiation emitted in your eyes, this will burn your retina. That simple.
And there is NO evidence at all that there’s a relationship between that blue light and human retina damage. None whatsoever.
Tell that to cell phone designers & display designers as it is in many phones & monitors.
You can control blue light emissions with software.
The shudder glass is not the blue light protection.
It is software. Now you can also get film to cover display that has filters blue light but will also cause mild bluring as all protective film does.
Walter old tv & monitors used tubes which are said to be bad. As for fluorescent tubes can have reduced blue light by design. Grow bulbs for example havevmore blue light.
Now were talking leds which can have a variety of spectrums.
If blue light was as bad as the study suggests then all office workers from the last 20 years would require glasses. Prior to lcd with tube even more would have glasses due to eye damage.
Now GP I read tge english version of the study in english. Key word may cause not to be taken as does cause.
For example Dish soap is considered harmless; however some may get rashes as dish soap is considered mildly toxic (T symbol in WHMIS).
Now here is the Assignment.
- Look up Blue Light emission of the Sun
- Audit the lighting in your home. Light bulbs have many ratings. Light Spectrum is usually given in a K value. If mem serves 5000k is around sunlight.
You are exposed by a ton of Blue light everyday from non Monitor sources.
Exactly ! Intensity is the key, and the intensity of light outdoors is much higher than any indoor device, and the spectrum is wider and includes actually damaging UV light, that’s way worse for your eyes than the bluelight coming from your monitor.
Well like i said if it was definitive we’d have more almost blind office staff who spend at least 7 hrs a day staring at monitors in the past crts now lcd.
And you did post that a doctor(s) suggested the glasses folks are buying may not be helping as well as folks think they are.
2 months without those filters and… Still seeing!!! LOL
There has never been an issue with crt screen due to blue light.
The issue comes from the led used for the backlight in the new lcd screens.
There is no issue with OLED because there is no backlight.
