I guess it maybe known to many of the people posting here, but for those who dont know, it seems there is a tablet and smartphone going to be released in the upcoming months from a company called Onyx that seems to be friendly to the eyes. These devices use e-ink front lit displays just like kindle paperwhite and last for week in terms of battery.
Let's hope other companies follow this eye friendly technology.
Great find, just curious if anyone one else noticed something critical near the end of that video. When he had a back lit display phone laying next to the prototype phone did anyone see how badly the regular phone was flickering? You can often see flicker in almost all monitors back lit with LED, I believe it's flicker in combination with spectrum causing the issue for us.
I also have another question for everyone who would care to answer:
How many of you have had a concussion or several hits to the head in your life of varying degree even if they did not result in a hospital trip?
I had a recent visit with a Dr. who believes my light sensitivity is most likely related to too many thumps to my squash:( There is more to it than that and I will write it up on my site when I return from vacation in a week.
I've banged my head twice, once when I fell off my bike when I was about 10 and once a years back when drunk. But If I asked the same question to most people I believe you would get very similar stories. Two of my friends who are unaffected, one has been hit on the head by a discus in school and the other is notorious for drunken head injuries haha.
I was just at the eye doctor trying to figure out my recent sensitivity to light. The sensitivity seemed to start after I had been using my ipad for reading for several months. I stopped using the ipad 6 weeks ago, but am still having the sensitivity to light - including while on my Dell monitor. I've dimmed my monitor to lessen the intensity, but it still bugs me to be at computer for too long.
The eye doctor thinks it might be due to my dry eyes, allergies, or due to the glands under my eyes that are dry or blocked. I've always had the dry eyes, but with age it has worsened. Anyway, she recommends that I try Systane Balance eye drops for the dry eyes for a few days and massage lower eyelids lightly (or with q-tip) while in hot shower. I'm trying this for 4 days, and if I don't see results, she wants me to try prescription allergy drops for the eyes. I'll keep you posted if any of these treatments help.
I have big problem with led monitors/tv and i have suspected that it is the pwm flicker that has caused the pain in the eyes.
Eizo has come out with a new series monitors that do not have PWM flicker over 20% brightness.
I recently bought a monitor from the series (ev2336) and was fully convinced that the problem was finally solved.
But to my disappointment, i get the same pain in the eyes :(
There's something about the light spectrum from the led lights that are completely wrong.
I have also tested glasses that block out the blue light, but it does not help either.
So now i have gone back to my old Dell 2209WA ccfl monitor again.
There will be problems to get a monitor i can use the day the Dell monitor break: (
I was just reading about cfl lights also causing issues. We recently had an energy audit and they switched all of our light bulbs to CFL. This happened around the time my light sensitivity started getting worse. I'm not sure if that is part of the problem or not. I just ordered some Gunnar Optiks eyeglasses that are supposed to block out the blue light so I'm hoping maybe they will help while on the computer. Meanwhile, researching possible causes - on the computer - probably doesn't help.
I hope you have better luck with the Gunnar Glasses than i had. I got worse eye strain with the glasses
And yes, you can get worse light sensitivity from fluorescent light.
Despite all the technological advances over the years, the light from old-fashioned incandescent bulbs is still superior and best for us all in the long run.
I think i will try to replace the backlight with incandescent bulbs on one of my old monitors.
I visited an office in a near town where all lamps where leds. Needless to say that i experienced a headache in 5 mins while waiting in the waiting room. I told the clerk about it, and she told me that from the time the company switched the lights to leds, she had severe headaches every day.
The strange thing is that she had an iphone 5, and when i asked her if she got headaches/eye strain/feeling dizzy when using the phone, she was negative. She actually claimed that she looks at the phone very often because she uses facebook a lot. What she insisted is that if she was out of the office she was fine even if using the phone all the time. She told me that last week she was on vacation and she used the phone all day with no such problems. Explain that!!!!
I have had issues for about a year and a half. Around when I started having the issues, I had head trauma. I have had two more head trauma's since. However, when I started having the issues, I was also using a brand new MBP and apple cinema display at work.
I went to a lot of doctors to see what was wrong with me.
I found I had a neck trauma from my head traumas. Seeing a good chiropractor to straighten my neck solved a lot of low-energy issues for me. If you have had a head trauma, consider seeing a chiropractor. A single visit is cheap and it can make a world of difference.
But I still have eye issues. One thing I learned is that I have exotropia in my right eye. I don't believe I ever had this before. I've gotten prism in my glasses, which helps, but I still cannot be on my computer for too long before I get very bothered.
Do other people have exotropia? Have you had it for life?
Then, after reading this thread, I realized that the problem might be more than needing prism for exotropia. I may now be extra-sensitive to light (I never was before). For the last 3 days I have been wearing sunglasses 24/7 (just normal ones, like these http://cl.ly/2n0N1y1O163z) and it has been helping. Today is my first day back on the computer, so we'll see how it goes.
Does anyone know of a laptop with a screen that won't bother them?
I can confirm that Galaxy S4 screen uses PWM on 240 Hz and irritates my eyes quite easily. It helps when the Backlight is 100 %, but since in AMOLED all the pixels control their individual brightness, there are allways pixels that are not 100 % bright.
Galaxy S4 Active, which has TFT Screend did not irritate when brightness was 100 %. Other brightness levels were extremelly bothersome. But on full baclight, it consumet the battery in no time, so it was not usable.
