Re: Spending many hours reading from an LCD? Tired eyes?

I am unable to read from my computer, I don't know why, I can not concentrated. So since I have my little Kindle what I do is (from a program from Chrome but I really don't know which one because a friend did the job but I can ask) to go, take the article I want to read and this program puts the article in my Kindle. It is fantastic because from the Kindle you can read anything you want, not just books. I do the same with the threads here. You select the thread, and this program take it and send it to your Kindle. Marvelous.

Re: Spending many hours reading from an LCD? Tired eyes?

Just want to add from what i found, to be precise, that EIZO provides the mentioned screens with a hybrid technology which uses PWM for brightness up to around 18-20%, but no PWM for the higher values.

That is correct. And DELL is also using the same method. It seems that LED backlight cannot regain the same color quality below 20% of brightness level without PWM so that's why they must use it.

I think that is good enough from my point of view.

Me too. 20% should be low enough.

For the 2013 models (or at least some), DELL is trying to catch up and use the same technology. Hopefully, other producers are already following and their competition will push the prices down and variety of sizes up.

EIZO will always be expensive, so it is up to DELL to introduce new technology into lower models. Unfortunately nobody is testing the cheap versions of DELL 2013 models (P2313H, E 2313H, E2213H, P2213, E2213, E2013H, E1913, E1913S, E1713S) and I cannot go to store and test monitors by myself because they won't turn them on so I don't know if they have PWM or not.

P.S. Nice to see some CZ links here ;)

Haha. Not that I had any choice. Those are the only websites that test PWM in monitors. ;)

I almost envy you your ability to enjoy kindle, it's great it works for you
Me on the other hand need to sit at the table with a real dictionary and another one on the screen to be able to check everything (obviously, since my English is far from perfect), having usually opened a few other articles/texts at the same time for references and that is something that i could not do on a small screen of a kindle thing. This way also allows me to keep attention on my posture etc.
But thank you anyway - someone else might pick up your offer and ask. By the way, i wonder whether such a device is really safe when close to your body even with wi-fi turned off. Are there any spinning things (e.g. hard drive) or is it kind of EM-free? Just speculating out of curiosity...

Haha. Not that I had any choice. Those are the only websites that test PWM in monitors. ;)

You see? Meanwhile myself being from the country and did not know! Thanks a lot ;)

Re: Spending many hours reading from an LCD? Tired eyes?

Anka, you have a dictionary in your Kindle, so this is fantastic. I really don't know about the radiations of a Kindle but there is also radiations from the computer. In Kindle you can choose the format of your letters. And you can bring with you thousand of articles in the little Kindle without the weight of it. But the most important thing is that your eyes are not tired when you read in a Kindle. And that is very, very important. By the way, I am not a saleswoman of Kindles.... :P

Re: Spending many hours reading from an LCD? Tired eyes?

I have one of the black and white Kindles too. I bought it rather than another kind of e-reader specifically because it does not have a back-lit screen. I also don't like to read large amounts of text on a back-lit screen.

There is no spinning hard drive in a Kindle. My guess is the EM radiation would be very low with the wireless switched off. Probably much less than other fields surrounding us from wireless technologies - cordless telephones, wireless modems, cellphones.

The Kindle battery life is about 10 days, reflecting its quite low power usage, compared with relatively higher-powered devices like lap-top computers or tablets, or the newer back-lit Kindle Fire (which is also a tablet, rather than a mere e-reader), where battery life is measured in hours rather than days.

That was interesting, so I looked it up. It's called Send to Kindle and will send the article over WiFi to your Kindle from Google Chrome. There is another one called Readability. Here are the links:

Re: Spending many hours reading from an LCD? Tired eyes?

If I'm not mistaken there is a thread somewhere about other adjustments of which I've forgotten the title and indication. Those had to do with a smoother transition from reading very late on PC and going to bed directly afterward. That's all I can recall.

There is some software called f.lux that automatically dims your screen at sunset.

f.lux makes your computer screen look like the room you're in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.

Tell f.lux what kind of lighting you have, and where you live. Then forget about it. f.lux will do the rest, automatically.

I tried to use this software from the above link and it worked great... for a minute. Somehow it must have had malware attached to it because my computer started acting weird after I installed it... so I had to delete the program and get some help removing the malware from McAfee. FWIW.

Re: Spending many hours reading from an LCD? Tired eyes?

I wanted to thank the OP. I used to set my LCD (DELL E2211H) at low Britgness and high contrast and never noticed any pain from it.
When I changed to Max luminosity and 'reasonable' contrast, most of my headaches were gone. I put the same parameters on the other screens of my family. Thanks again.

Glaucoma

During a visit to an eye specialist, mainly to have a thorough examination of my eyes before returning to prescription glasses, I was told it appeared I had Glaucoma in both eyes and a Cataract on my right eye (this point I would agree with).

An MT ocular scan was done on the spot for further investigation and because it wasn’t conclusive I was given a referral for a MRI scan. I’m not confident in the specialist’s diagnosis, nor his rush to want to get me on drops (for life) to arrest any further damage, especially when 2 of the main symptoms are increased pressure inside the eye and loss of peripheral vision, which were not present in my case.

On searching in the forum for ‘glaucoma’ I found vitamins (especially C and D) and supplements help. I do take some vitamins including the above, but I think I need a good program set up to maximise my eye health.

I have made an appointment for the MRI scan in mid March though I’d rather not have to do this if I have other options.

Any help on this matter would be greatly appreciated.

I'm sorry to hear that, Lindenlea. But take it seriously too, cause these are your eyes and especially the nerves of your eyes are endangered to get damaged cause of elevated pressure. And glaucoma has the tendency if not treated to develop slowly and decreasing vision.

Try to get other professional opinions on it, to prove or falsify this diagnosis. And what did they measure so far (intraocular pressure of left and right eye? The norm is about 18-20)?

 

[LQB]

Re: Glaucoma

I agree with Gawan - Glaucoma is something to take very seriously if you test positive for elevated pressure. I have read that cataracts can be dealt with via diet - but nothing about diet and glaucoma. As far as I know, there is a genetic component to glaucoma and it is often passed down through the generations. My grandmother went totally blind from it (so I look forward to the pressure tests). Occasional drops in the eyes is a minor annoyance compared to loss of vision.

Re: Glaucoma

I've been taking arginine, L-Carnosine, niacin for small vessel clean-out. PLUS using a 25% solution of DMSO drops in my eyes every day. I'm going on two weeks now with the drops and I am convinced they are helping.

I didn't start out with a diagnosis of glaucoma or cataracts, but my grandmother had both and my vision has been steadily deteriorating.

Re: Glaucoma

This is the first time I have ever heard of MRI being done for glaucoma. A quick search of the web yielded this article
http://www.mc.vanderbilt.edu/reporter/index.html?ID=8387

This has peaked my interest, since my husband has glaucoma and his brother (who is younger, in his late 40's) is nearly blind from the disease. He sent me his visual fields - he has just a very small central area of vision remaining (tunnel vision).

When I have some time, I will do some more research and post more as I find it. In the mean time, I'd likely do as Laura suggested and try 25% DMSO drops (diluted with sterile saline). I use it myself, but not regularly enough to note any effects. It is suppose to prevent cataracts (per the Dr.Morton Walker book on DMSO).

I'm sorry to hear you're going thru this Lindenlea. Keep us posted.

Re: Glaucoma

Gawan & LQB
Thanks for your replies, yes I am taking it seriously, I was just a bit put off by the Specialists umming and arrring as if he wasn't sure and my first thought was "let's see if I can get a natural program going whilst I'm waiting for more results", and when I do get the MRI (it's booked in anyway) there maybe an improvement on the situation.

I don't know exactly what the pressure measurement was as the Doctor was reading from the computer screen and just said "your pressure reading is normal, and your peripheral vision is good".

Laura,
Thanks for your reply, I have not used any of the products you mentioned but I shall start searching for them on the net.

I have previously tried to get DMSO in Australia but I remember there was a problem, we have so many restrictions on 'unusual products" in NSW (comfrey is one, Magnesium Chloride was another), however this morning I emailed a company in QLD as they sell 100% pharma grade, but only by the 1kg bottle, they replied without any problems, when I tried a similar order in NSW, I was told I would have to order it through a Vet. So hopefully I shall be able to get started on the DMSO and the other items pretty soon.

Lilou,
Thanks for the link, I had a quick read and picked up on this item towards the end:

The study, which also introduces the possibility of using MRI scans as an early diagnostic tool, was funded by the Glaucoma Research Foundation, the National Eye Institute and Research to Prevent Blindness.

Aafter reading the link there seems to be a whole new approach to Glaucoma, so I'm ok to go with the MRI now.

Re: Glaucoma

Thanks for the update.

I don't know exactly what the pressure measurement was as the Doctor was reading from the computer screen and just said "your pressure reading is normal, and your peripheral vision is good".

So it must belong to the "old" approach diagnosing it, since the pressure is the indicator for Glaucoma I know of.

Aafter reading the link there seems to be a whole new approach to Glaucoma, so I'm ok to go with the MRI now.

That's interesting, maybe it is a better approach to recognize it earlier. Which is also good imo, cause people do not get very often to an eye specialist and checking for Glaucoma or anything else, if at all.
