Heureka! That looks like the deal for me. Thanks a bunch, Persej!

I'm glad I can help. Don't forget to write mini review if you buy it. ;)

Yes, an amber tinted glasses or even original BBs can make a big difference for many.
And have you read this Blue Light... thread ?

anka, thanks for mentioning the Blue Light thread which I wasn't aware off.
 
Re: Glaucoma

Sorry to hear about your Glaucoma -situation Lindenlea. Perhaps the "accommodation spasm" of the eye could play a part in the increase of the eye pressure, especially if you are nearing/ have passed the presbyopia age, and are hyperopic (your eye prescriptions are of "plus" value = the eye is "too short"):


AN EXPLANATION FOR THE EVER INCREASING GLAUCOMA DIAGNOSES
A reaction to the article ”Primary angle-closure glaucoma increasingly widespread in European-derived populations”, published in the European

Edition of the Ocular Surgery News (Volume 23, Number 8, September 2012).
_http://www.healio.com/ophthalmology/glaucoma/news/print/ocular-surgery-news-europe-edition/%7BADBE61EA-E170-490A-97A1-36947C003ABD%7D/Primary-angle-closure-glaucoma-increasingly-widespread-in-European-derived-populations


The article discusses a review published in the British Journal of Ophthalmology, where the prevalence of primary angle-closure glaucoma is
examined. It is more widespread (increasingly so in the near future) than previously thought. The role the accommodation spasm plays in the development of glaucoma is unfortunately not mentioned.

In the same issue of the Ocular Surgery News, an article titled “Primary angle-closure glaucoma most prevalent in Asian patients but growing worldwide” is also published. Within the prevalence of the angle-closure glaucoma is dicussed; how the majority of cases are situated in Asia, but an increase in cases is also occurring worldwide. However the accommodation spasm’s influence in the matter is not brought up. _http://www.healio.com/ophthalmology/glaucoma/news/print/ocular-surgery-news-europe-edition/%7B44FC430A-43F7-42C1-866A-482966054BE1%7D/Primary-angle-closure-glaucoma-most-prevalent-in-Asian-patients-but-growing-worldwide

The accommodation spasm strains and swells the accommodation muscle (m. ciliaris, whose processus ciliares are responsible for secreting the aqueous humor). Also the lens of the eye thickens, producing stronger refraction. On top of not working in an ideal fashion, these swollen anatomical structures take up space and narrow the angle: the circulation and outflow of the aqueous humor are decreased, and the intra ocular pressure increases.

It is to be mentioned, that if the myopization starts at an early age, in a growing person the eyeball can anatomically elongate causing the angle to open up. But the later the accommodation spasm develops, the eyeball does not “give in” and the problematic situation arises.

The widespread increase in the intra ocular pressure starts to markedly increase from the early presbyopic age. At this point as the lens of the eye starts to lose its elasticity, more work is required from m. ciliaris and the accommodation strain is severely increased.As an example of the accommodation strain, the increase in the intra ocular pressure is essential.

Especially in those who are strong (latent) hyperopes, due to the greater accommodation strain, the angle is narrow and the intra ocular pressure increases as a result.

The earliest and as complete as possible correction of hyperopia, was stressed already in Panacea (1978), pp. 344-378 (especially the chapter “Prevention” on p. 371). Within Panacea’s extensive glaucoma -related discussion, is mentioned the fact, that as long as there remains even a slight potential for hyperopia correction, the rise in intra ocular pressure can not be held as separate glaucoma.

As is known, the amount of close work has increased considerably in the last decades (eg. computers). The ensued accommodation strain and its appropriate treatment have both been neglected by the profession at large. Naturally the prevalence of glaucoma has increased.


How often one sees “unexplainably” bloodshot eyes after tiresome close work – these are then treated with a variety of different, harmless drops, to the benefit of the business!

If proper attention was paid to the issue at hand, what a service to the mankind as a whole it would be with the resulting avoidance of unnecessary treatments, perhaps including even surgeries. The writers themselves mention iridectomies failing to bring results.

How the accommodation spasm can affect the eyes, and even radiate further through the nervous system, with adverse effects elsewhere in the body, is very interesting. There's some info about the matter in another thread:

Re: Glaucoma

Thanks Hiker, that was a good article, also the link.

My eyes have always been plus since I started to wear glasses for close work in my late twenties, which was very intensive concentrated work. I also ended up with an astigmatism along the way.

When young I had perfect vision, I was the 'hawk' that used to find the pins and needles dropped on the floor. It suprised me to be in glasses so early.

In my early forties when I went into bi-focals I tried soft contact lenses, which I couldn't get used to, so back to glasses. Then 12 or so years ago I had Lasik surgery after hearing of many success' for long sighted with astigmatism. This seemed to be successful, but over the years my eyes have slowly moved up the plus scale.

During my last specialist visit to check out the MRI results, everything was confirmed as the previous diagnosis, the doctor said pressure readings can be affected by lasik as the cornea thins. So he started me on drops to reduce the pressure in the left eye (first) as that was 15 and the right eye was 10. So every night I instill 1 drop of Xalatan in my left eye and in 2 weeks I have another pressure test to see if it's working.

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.

Hi Lindenlea,

I missed this thread earlier. Have you been able to obtain DMSO yet? I bought mine from here: http://www.horsesuppliesdirect.com.au/category63_1.htm It is for the horse but I think it is good enough for humans. If you still have problems, let me know and I'll mail you the half bottle I have now.
 
Re: Glaucoma

Hi Bobo08,

Yes I did manage to get DMSO (1000 gr) from QLD, but in the meantime I'd started on some drops from a compounding chemist in Ballina, so in between going up and down the coast with the house and weather, I decided to keep the DMSO sealed to start on later, so I'll use the Doctor's drops to see if the pressure comes down in the next 2 weeks.

I must admit I was a bit alarmed at first when i read all the danger signs all over the DMSO bottle, but that's the government rules and regulations for you. I also need to buy other items Laura specified in her eye management protocol.

From what I've understood about the accommodation process/ accommodation spasm, even if you have had Lasik surgery, it might be good to wear the plus, especially when doing close work. Elder relatives of mine have benefitted from Xalatan too, to reduce the pressure initially. Also Laura's protocol will surely help!

Hope things will improve soon :flowers:

Cheapest PWM-free monitor so far: 21.5-inch Acer H226HQL for 150 $/€: _http://extrahardware.cnews.cz/recenze/acer-h226hql-barevne-verny-jemny-levny-leskly-ips-bez-pwm-test

There is also bigger version from the same series: 23-inch Acer H236HL for 180 $/€, but not tested yet. Both are glossy.

I wrote to Acer, asking about all of the screens and they confirmed that 21.5-inch Acer H226HQL has no PWM and that it is their only model built that way. Still, very interesting pricewise.

Very simple explanation of eye fatigue when using LCD monitors: http://www.eizo.com/global/library/basics/eyestrain

Three subjects are covered: PWM, brightness level and blue light.
 
Re: Glaucoma

Well I had my eye pressure test again and it went down to 9 in both eyes, so now I'm doing a drop in each eye of Xalatan. I've also switched treatment to a local Eye Specialist and his latest pressure test showed both eyes at 8, so it seems to be working.

The cataract in my right eye is very noticeable now, so I have the day surgery procedure scheduled for next Tuesday, 11th June, I'm feeling a little apprehensive as the time draws nearer, as I don't like my eyes fiddled with at the best of times. I will be making good use of EE in the coming days :)

Second that! I hope everything goes well, Lindenlea.
 
Re: Spending many hours reading from an LCD? Tired eyes?

Lots of new flicker free monitors coming from BenQ soon. All future models will start to be PWM free later in the year. Always good news!

I hope it's true.

BenQ to Expand Flicker-Free Monitor Range

In what will no doubt be a popular move, BenQ have decided to embrace flicker free backlighting across pretty much all of their new range of screens as they are released throughout this year. They were the first manufacturer to widely adopt 16:9 format, LED backlighting and AMVA + LED across their range in the past and now they've decided to look out for their customers again with this new technology. The backlights will not use PWM for backlight dimming and instead use a Direct Current (DC) method to avoid flicker. This forms part of BenQ's "EyeCare" initiative encompassing flicker free, new preset modes for reading, ambient light sensors and a new cabling supply to package digital cables (HDMI or DVI) with their new monitors instead of older analogue D-sub cables.

The BenQ GW2760HS is one of the first models in their new flicker free range which we have with us for review at the moment. Review coming soon! Expect lots of new models across their range in all sizes from 21.5 - 27" to be launched throughout the year from BenQ with flicker free backlights.

Bravo BenQ! :)
