Awesome for headache sufferers

This new "eyecare" line of monitors from BenQ are a godsend for people with eyestrain and headache issues from viewing computer monitors. My employer graciously got me 2 of this particular model as soon as I found out about them.

I have suffered from migraines for over 20 years, but 2 years ago I started getting them almost every day I came into work. This precipitated seeing numerous doctors and specialists, lots of medications, tests, expensive acupuncture, vitamins, diets, you name it. Some things helped but the migraines persisted. Over 6 months ago I discovered wearing dark-orange sunglasses in the office caused a significant improvement, down to 1-2 migraines per week. I also tried prescription tinted computer glasses, Gunnars, MigraLens, and others, but the sunglasses worked best.

The obvious triggers here were the computer monitors I was staring at and surrounding lighting conditions. But to do my job there was no way of getting around that. PWM, the technology nearly all LED monitors use to reduce the brightness from 100%, makes the backlight of a monitor turn on and off rapidly, creating a flicker effect that is mostly imperceptible but can cause eyestrain and headache in those who are sensitive to it. Some people suggest turning the brightness to 100% to avoid PWM, but that creates a high-contrast situation that is a migraine trigger in itself.

This monitor does not use PWM at all. There is additional circuitry added to allow it to adjust the brightness through direct current (DC) instead. This makes a world of difference in the overall comfort of viewing the monitor. Even my non-migraine-suffering coworkers have commented that these monitors are noticeably easier on the eyes. Using these monitors I am able to work pain-free and without sunglasses. Words cannot describe what a relief that is.

The blue light-reducing feature is a nice convenience as well, although a similar effect can be achieved on any operating system easily using the free f.lux software program. I had used that on previous monitors but it wasn't enough, PWM was clearly part of the problem.

Thanks for this information, Persej. Protection of my eyesight is always in my thoughts as I only have the one eye, and the vision in it is by no means 20/20. I spend hours every day on the computer and that will remain the case for the foreseeable future. I had never heard of the BenQ technology so I am grateful to you. I'm ordering a BenQ monitor tomorrow.

I'd appreciate knowing what you think about Gunnars. Reviews are very positive and I intend to use a pair of them in conjunction with BenQ. How did you find using them? Thanks.
 
I never used Gunnars. That is a customer review I found on amazon, not my review. BenQ is a company, not a technology. And only some of their monitors are flicker free, so you have to be careful. EW2440L is OK.

You can also take a look at LG monitors. Here is a list of LG monitors with “flicker-safe” technology:

16:9 ratio:

22": 22MP55D, 22MP55HQ, 22MP65D, 22MP65HQ.
23": 23MP55D, 23MP55HQ, 23MP65D, 23MP65HQ, 23MP75HM.
23.8": 24MP55D, 24MP55HQ, 24MP76HM.
27": 27MP55HQ, 27MP65HQ, 27MP75HM.

21:9 ratio:

25": 25UM65-P
29": 29UM65-P
34": 34UM65-P, 34UM95-P

But you should always check their specifications at LG's website, or ask here about specific model that you like.

Ah, I took from "I also tried prescription tinted computer glasses, Gunnars, MigraLens, and others, but the sunglasses worked best." to mean you had actually tried Gunnars. I failed to see the significance in the Amazon link at the bottom.

Many thanks for your advice about the monitors. I'll make sure to select a flicker-free one. Thanks again.
 
A couple of days ago I finally bought my first flicker free monitor!
I bought LG 22MP55HQ. I got it for 125 euros, after good discount.

It's an IPS monitor, but color gamut is only 72% so I'm not amazed by color reproduction, although I really can see certain colors that I couldn't see on my old TN monitor. Black is okayish, but not great because there is present famous IPS backlight bleadthrough. Viewing angles are better than on TN, but also nothing spectacular. Overall, picture offers slight improvement over good TN monitor.

Greatest strength is of course flicker free backlight, which is a must have if you plan on buying a monitor with LED backlight. Which today they all are.

OSD menu is the worse I have seen so far. It is too difficult to change anything on the fly, such as changing the picture mode from "normal" to "cinema", when you want to watch some movie for example. You will often have to use all 5 buttons, which will feel almost like you are playing a piano.

I also stumbled on the folowing problem:

When you have a completely dark scene in the movie, the monitor will try to save the Mother Earth from evil human beings and their evil CO2, by switching the backlight off, after witch it will need to turn it on, which will "eat" a second or two of your movie!

But thankfully there is solution for this annoyance - just turn on the "Super Energy Saving" function either to high or low. Fine, you say, I will turn it on and will never have to worry about it again. Think again, CO2 lover!

Every time you change the picture mode from "normal" to "cinema" or "text" or whatever, the SES function will switch itself to off. Which you will probably forget about, until the next dark scene comes...

The power of the monitor comes from the AC/DC adapter which is great because this monitor emits no buzzing sounds. And it consumes only 20W or less.

Overall, it is a good buy for 125 euros, but I wouldn't pay for it much more than that.
 
Hi,
I would like to present a recent event concerning ocular health. I started to see flashes of light especially at night, then all of a sudden a rim of a circle formed in my field of vision and a few fixed floaters.
The diagnosis was epiretinal membrane:
http://www.eyeinstitute.co.nz/the-eye/eye-diseases-and-conditions/epiretinal-membranes.htm

Could turn very unpleasant and the said, one has to wait and see...maybe surgery could help.

Well, I wasn't too enthusiastic to just wait. I turned to Chinese medicine explanations and come to an understanding that the main cause should be poor blood supply and circulation to the eye.
Therefore I started a self devised treatment consisting of blood supply enhancing products such as:

- a cocktail of blueberry- Hawthorne - goji berries (could use extract of these if no raw berries are available)
- ginkgo biloba extract
- B vitamine complex megadose
- magnesium oil under the arms and on the chest
- coffee mixed with the juice of one fresh lemon

- daily exercise of taichi and chikung for one hour

I also stimulated some acupoints related to blood supply ( mainly liver, kidney, spleen, stomach and gallbladder meridians).

Now, after one month of treatment the "images" in my field of vision have faded almost entirely.

I thought that by sharing this experience, maybe I could be of help to others who are experiencing troubles with their vision which are, mainly due to poor irrigation of the eyes (blurred vision, red, soar eyes, floaters, etc).

If somebody is interested, I'll be glad to help

Haven't found any info on this elsewhere and I am prompted to post this information after reading a recent SOTT article on nearsightedness. Natural vision improvement. Pioneered by William Bates. It is how you can train you eyes very easily back to full health. This really works! The exercises are simple and easy to do it just takes a little bit of effort and perserverance. If anyone is concerned about their eyesight or eye health, it is worth looking up. Other professionals have continued Bates work, Janet and Carina Goodrich and quite a few others. I know it works for myself and others. It is simple and powerful. I will be interested in hearing peoples experiences because I guarantee it is a revelation. Train your eyes back to perfect vision. There may be other factors also that need considering ie. posture and diet etc. I apologise if this is already on the forum somewhere but worth a revisit.

Hi Shared Joy,

Since some months I have problems with my eyes, specially floaters. It is so complicated to have an appointment to a doctor here, if you don't pay. I have Ginko at home, in pills, is this good? You talk about acupoints, can you be more specific?

Thanks!
 
Hi Loreta,
as I have mentioned, you need all the products listed in order to both blood supply and organ stimulation.The accupoints I used were according to my body needs.

In my case, I stimulated the points around my eyes (belonging to urinary bladder(1,2) and gall bladder (1,14) channels), also those on the liver channel (No. 3,8,13), also distal points of gall bladder related to eye issues (no.19,20,37,44), also the large intestine channel (no.4,11) to eliminate toxins and circulate blood, the stomach no.36, spleen 6,heart 7 to make blood.
I don't know if you can manage to do it yourself or find somebody to help you, but these points should be combined according to specific necessities. I indicated here only the main points. It requires some previous knowledge to benefit from them!!!

However, floaters are generated by coagulation of collagen inside the eyeballs which eventually precipitate and disappear from your field of vision. I will paste here several links where you can get some additional information

Thought I would post here about the blurred vision I experienced instead of creating a new thread. Plan to read more of this thread soon.

Happened a couple weeks ago or so after waking up from a disturbing dream. There was a rainbow (faded in color) halo effect around the night lights in the house. There was a halo effect around the lights on certain appliances, but only of the light on the appliance, not a rainbow effect. Finding it a little challenging to explain.

Reading up on it on Wikipedia, seeing a rainbow halo effect around lights can indicate swelling of the cornea, which is linked to Corneal Edema. The bit I read indicates that the swelling can occur when the cornea is unable to keep itself clear, and fluid begins to accumulate. My eyes did feel cloudy, as if I had fluid in my eyes.

Anyone else experience this? It hasn't happened since, and I don't remember it happening before. Think I may get my eyes checked though after reading what I have on it.

I found an original copy of William Bates' book at a garage sale, and read it with fascination.

I did the exercises for about three months, and started getting the clear flashes. It was astonishing!

Then I found myself in a position where I had to rent a car for a couple of weeks and needed my glasses in order to drive it safely. Phooey! Right back to square one. But I can say that it was beginning to work.

I've not gone back to the exercises. I don't wear my glasses really ever anyway. The world is a bit fuzzy, but I find it doesn't bother me, and my near vision is sharp.

Still, I do highly recommend the Bates method for anybody who can afford to spend a year at it!

Hi Cleo,

I am an optometrist, so I thought I'd chime in here. There could be a number of reasons why you noticed halos such as:
* corneal issues (edema or dystrophy for example)
* raised intra-ocular pressure
* refractive error (i.e the need for a spectacle correction)
* cataracts etc. to name a few.
There can also be systemic reasons for halos, & flashing lights such as noted in migraines. Silent migraines have the visual phenomena but without the headache.

If you have not had a check-up recently, it may be a good idea to do so :)
 
Hi Arwenn, thanks for the info. I don't wear prescription glasses and don't really ever get migraines although at times I do get headaches (usually only when I go without caffeine). The other day people at work were talking about the migraines that they get. At the time, I was actually thinking of how seldom I get migraines but maybe the blurred vision could be from a silent migraine. I haven't had my eyes checked since 2005 I believe so I think I will be looking into it here soon.

I've since wondered about the connection between the disturbing nature of the dream and the blurred vision, not sure but maybe the state of mind I was in, in the dream, contributed to it somehow.
 
Hi Cleo,
according to Chinese Medicine, both vision and dream disturbed sleep are attributed to stagnation of the liver energies, due to low blood levels in the organism . It is like having not enough oil in your engine - when running, your engine heats up. When insufficient blood is kept in the liver, you'll have too hot blood delivered to the organs, which disturbs the whole organism. Therefore the main issue is to stimulate the organs responsible for generating blood (this could be a different procedure in each case, depending on the organs which are deficient such as stomach, spleen, heart, kidneys). Also there are some herb combinations which promote blood supply sufficiency.
You might have some practitioner to offer qualified help.
I hope you'll find this beneficial. Best wishes!

Hi Shared Joy, I have since looked a bit into liver qi stagnation, and the symptoms that I've found on this condition online do seem to mostly match up. Is there reading material on this topic you recommend? I do seem to be more easily tired or fatigued at times. The analogy you gave, reminded me of the way in which I've talked about my job (that I started last year) and the stress from it at times-that of feeling 'burnt out' by it.

Writing what I have, networking about EE could also be of real help I think, something I'm still not sure that I'm doing all that well at this point.
 
Hi Cleo, sorry that I can't help more than sending some links. But I do hope that getting some info will help you in choosing a treatment
Here you are:

List of symptoms for various disruptive patterns, also recommends some pills, though the practitioner would usually change the formula according to the patient’s personal needs.
