CRT radiation shield

Can anyone in Aus/Brisbane tell me where to get one for a 19inch monitor? I was given the monitor recently and have a mild case of fried eyes.

A radiation shield? Never heard of such a thing. If you are suffering from eye strain or fatigue set your monitor vertical refresh rate to 85Hz to reduce flickering.

Thanks Jordan, I'll try that. Check this link for radiation shield. http://www.lessemf.com/computer.html

This pertains to only CRT type monitors. I used to sell radiation shields, many many years ago, but they have become quite scarce in the U.S. There is no longer a need for radiation screens on monitors and most of the screens being sold today are nothing more than anti-glare screens.

Sometime in the late 1980s the Swedish standard (MPR1) came out and in 1990 it was updated to the MPR2 standard. That standard was adopted internationally and in most countries, including the U.S., only CRT monitors that met the MPR2 standard could be sold. I suspect that holds true for Australia as well.

In 1992 the Swedish Confederation of Professional Employees introduced the TCO standard, which describes radiation emission levels based on what is the minimum technically achievable level rather than the minimum safety level. The TCO standard was revised in 1992, 1995 and 1999.

Bottom line, unless you have a very old CRT monitor build more than 20 years ago, and you spend a lot of hours in front of it, there is no need for a radiation shield.

Thanks Brooks, I was wondering why I found nothing in search.

Besides flicker from a slow refresh rate, tired eyes can be the result of insufficient ambient light, or poor crt focus. You may also want to get your eyes tested. Many problems can be traced to incipient presbyopia, and sitting too close to the monitor (but this applies to more than crt).

if you already do, youre all set

Definitely make sure you're running at a high refresh, in regard to the ambient lighting, if you can get a bit of light behind the monitor it can help a lot to reduce the sudden contrast between your monitor and its surroundings. A quick google shows up this page http://www.hometheatermag.com/bootcamp/49/index1.html , plenty more on the subject if you're looking around.

I have my optometrist write a prescription for computer viewing distance, and get computer glasses made.

Early last year we started ordering our prescription glasses from http://zennioptical.com/ (other countries probably have similar places to order from), where the glasses start at $8 complete, and we were very satisfied with the 8 pairs of glasses we ordered last year (for less than a single pair at a store). A few days ago we ordered 11 more pairs using our new prescriptions.

I ordered 2 distance, 2 computer, 2 reading, and 1 multi-focal pair, and Heidi wanted lots of different frames, so she ordered 4 different frames or her regular prescription (she wanted to order more, but I got her down to 4).

Just to confirm...

The 19 inch monitor given to you is a CRT.

I'm thinking you were given a LCD that is set to a default blindingly bright level but are asking for an old CRT shield thinking it will help.

Thanks all for a generous response, many things to consider. I use reading glasses, I sit close to the screen, for too long at times and it is a CRT screen with brightness lowered, low ambient light, dimly backlit.

One thing to consider is that a lot of people in you age range have more ore less dry eyes and the reduced blinking rate experienced while looking at a monitor or reading usually worsens the symptoms. Moisturising eye drops might help as well.

Distance from your eyes to the screen should also match your your prescription. A vast majority of people can't watch the monitor for prolonged periods with their distance or reading glasses only. Check at your optometrist or eye doctor.

I am now taking a break from the monitor, only checking this thread and mail, keeping my distance, lowered the brightness again, started using eyedrops. All the best.
