Am just wondering how many members are wearing glasses or contact lenses. And if you think if this is related to looking at a PC monitor for too many hours per day.
And of course, security also means keeping your eyes healthy so any advise about possible dangers about computer monitors and their influence on your eyes?
Would an LCD screen be a better option than an old-model monitor?
Hey i've got my monitor with an anti-glare screen fixed for the purpose of care of my eyes. Its a must to take care of ur eyes. You should wash ur eyes every 3 hrs of contineous computing. It helps in concentration and reduces the stress on eyes.
Its a very valid poll as computers are blamed by most parents for causing damage to eyes of kids.
By the way i dont use glasses or contact lenses. My eyes r good.
My eyes are getting tired.....age I guess :(
My doctor told me to move my monitor further away...
Or get a bigger one...
So I did both ;)
MLF
On a more serious note...refresh rate may help
I wear contacts but I recently bought some expencive glasses because contacts dry out and go all weird when I use the computer for prolonged periods of time, so I kinda need them to do my job, that and I am blind as a bat without my contacts >.<
TFTs are better than CRTs in most cases, one being that CRTs acctualy irradiates you.....tiny amount but its always fun to remind people that CRTs with by Beta emission.
i've been in front of computers all of my life. i think my vision problems are hereditary. my prescription has been the same for several years now.
lol, like the one-and-a-half electron that gets past the membrane ;)... I get more radation from a glass of waterQuote:

I use glasses, but don't wear them on a regular basis , only when requiredQuote:

I feel that reducton in vision is more to do with the aging process ( I should know :D) than sitting in front of a monitor all day, although it may have some effect . Any optician members want to comment?Quote:

Neel, I know :p But its funny to see people get fussy about it since Beta emission has a penetration range of ca 20cm....even IF it makes it through the glass.
In air yes.. but it won't even go thrue a single sheet of (standard 80g) paper..Quote:

I wear glasses but it's not because of the computer, I've worn glasses almost all my life (since kindergarten). About 85% of my fathers side wears glasses so I'll say I got it from them.
the_JinX, true, the possability of an electron passing through the phosphorus (sp?) membrane AND through the glass is practicaly 0, but that wasnt really the point I was making, what I said (sorry if I worded it badly) was that its fun to remind people that they are infact looking at an Electron gun. I find that the general public knows very little about radiation. :)

I don't nead specs yet, still got good vision, sometime in the future I expect to need then for reading and driving.
I'm not sure but I think companies over here are obligated to pay for glasses, if needed, by computer opperators? Nihil will probably know if this is true.:)
Hi katja,
You forgot ' don't need glasses yet but eyes starting to fade ' :D
Speaking of radiation...many if not virtually every appliance in your home generates radiation...the tv, fridge, microwave...but they say it's at harmless levels...;)
I remember back in the 60's the old man ( my father ) had a newspaper picture of a kid with the color burnt from his eyes...the article basically warned about the dangers of sitting too close to a color tv for long periods of time...apparently this kid was so fascinated with color television he sat and watched it everyday till he burnt the color right out from his eyes.
They've improved tv's since then.
Eg ;)
Eg, I also "forgot" things like 'my left eye is fine but by right is blind' or 'I have perfect tunnelvision'. :)
Am also suprised that we have two legally blind members here.
And well, TV's and monitors are pretty safe these days, I'll admit that. But since I'm sitting behind a large 21 inch CRT monitor at home, it is some 'security' thing that I am worried about. My health is very precious to me... ;)
I wear beer goggles when I get really drunk. Thats about it.
Though... I am due for a trip to the eye doctor. I wore glasses when I was younger. I grew out of them and my eyes got better. The doctor said I didn't need them anymore. I think I may need them again soon though. It now takes me less alcohol for the goggles to show up.
I've got a ridge in my nose from glasses
why don't I use contacts ??
They don't hold enough BEER :D
I am now at an age where eyesight deteriorates anyway [my excuse]
so it's reading glasses for me now.
as for the safety issue :
It has never been a 'good' place to sit, so close to the screen, and paying it a lot of attention,
bearing in mind that the average 'joe' sits around 10' / 3m away from the TV, and at that distance you are not so conscious of the glare
but there has also, never been any research that totally condemns the tube for the eyesight damage............
but, I'd say that TFT is the better, purely on the WEIGHT ............
I'm using a 19" CRT now, and it's right at the back of a BIG desk, and when it fails ...........
it's STAYING there :)
I'll prop the TFT against it........
Bifocals here or I can were contacts with reading glasses. All compliments of TV, monitors, constant glare off the ocean, forced reading in low-light, etc., etc., etc... :( (permanent ridge on nose & ears as well.)
cheers
What's also fun is telling people about the radiation an (older) microwave still emits despite the shielding (me friend put his phone on top of the microwave and it went poof, you can actually frie alarm circuits with a microwave beam through walls) and the radiation of radars all over the country (failing cars because their new superduper chips weren't shielded) or the radiation of riflebullets who are hardened with uranium (iraq in 10 years). Especially if they whine about wireless cards all over the place wich emit like so little even the radiation from nature does more damage.Quote:

I wore glasses from 7th grade thru 12th but not that im outta HS and in college i wear contacts, makes me look sexier i think :)
I started wearing glasses years before I was a computer geek, and since then my eyesight doesn't seemed to have changed any.
Probably caused by fox bitesQuote:
I never really had any problems with my eyes and computer screens.If my eyes get tired i take a break and go eat something or take a small nap.
I've worn specs since I was 13 before I'd ever used a PC but I was a heavy Spectrum user.
If you use a VDU for more than 2 hours a day as part of your job then your employer has to pay for you to have a regular eye test.Quote:
I'm not sure but I think companies over here are obligated to pay for glasses, if needed, by computer opperators? Nihil will probably know if this is true.
the employer can also be required to contribute up to 40% towards your eye care. I'm not sure how the last bit works I just remember the wording.
Just found -
Quote:
Under European legislation introduced in 1993, employers are obliged to pay for routine eye checks for all their staff who use a VDU for a significant part of their normal work. If it is found that the user needs eyewear specifically for their work at a VDU, the employer is also obliged to pay for a basic pair of glasses, or give the employee an equivalent amount of money towards a pair of their choice.
Yes ..my eyes hurt sometimes to ...but I find that drinking enough water a day keeps my eyes from hurting too much.
This SITE has some interesting info about eyes and using them to stare at a computerscreen .
It also got some tips for keeping your eyes healthy ... you have to read a bit in between the lines though :D .
I don't have to wear glasses or contactlenses ...but that doesn't mean I take care of my eyes.

USed wear specs only for driving.. the an illness took full grip now need them full time.. only been wearing glasses for the past 16 years, and full time for the past 7..
The reason was not Computer monitor related..
as for moniters.. CRT monitors emmitt a fair amount of blue to extreem blue light, this is the nature of the CRT, the phosphers that are being used and the display colours we prefer. The excessive exposure to the retina of this range of light frequencies have not yet been deemed as harmful. But working in a room that has the extreem of lighting can contribute to eyestrain.. either too dark a room or too bright ..
Also some people suffer "Eye Burn" a symptom of the excessive blue light, it is similar to Welding Flash, a burning sensation in and around the eyes.
Poor posture can cause problems, neck strain and eye related problems
Oh LCD's.. OI..... SONY, Samsung, Mitsubishi and Viewsonic Here comes a Rap that I think is worth a freebie or two to me..
Well built LCD's with low refresh lag, and balanced back light (yes the mentioned brands are in this group) good to excellent contrast ratio (low contrast is another contributer to eyestrain). Working infront of these screens for long periods leave the viewer with next to no eye burn, and in a balanced room light , and with excellent seating and desk arrangements users have the least complaints with eyestrain..
Samsung and Mitsubishi may not be the cheapest but they have the reliability.. Sony are just in a class of their own.. Suck suck lick lick .. that will be 2 x 21"wide screens and 2 x 19" 4:3 formats please
oooops thats an advortorial.. sorry for that guys.. .. But I will post the results of my suck up..
BTW: dont try this at home.. .. I am a trained in the retail arts.. and am aware of the dangers..
I don't think looking at a computer screen has any effect on your vision.
Eyestrain from looking at little tiny print causes no permanent damage,
but may affect your comfort and productivity. For centuries people have believed
that too much reading, or reading without enough light, or reading with the book
too close caused weakening of vision. I don't think there's any truth to it.
Now, staring at an electric arc welder, that's a different story.
:cool:
Crap.. True the default standard now is higher than it was 20 to 30 years ago.. But you only need the EHT on the moniter or TV to exceed the specification by 10% and the x-ray emmisions from the CRT more than double.. MAny of these Chinese sets ar not well built nor reliable. As a service engineer the number of these units that came in with some other issue and had escessive EHT voltage and therefore dangerous x-ray emissions (dangerous is when the emmisions are 1000th that of a standard Xray machine.. why that low? Because your sitting within 1 meter of the BOX not 2m as the standard for xray exposure is and youyr there for hrs at a stretch for days on end, not 10secs once in a while)Quote:
And well, TV's and monitors are pretty safe these days,
BS - Just go and have a talk to an Optometrist. that is a true eye specialist not an idiot that sell specs..Quote:

If your eyes are not working the full range of its capability regurlarly, it will settle into its common mode of operation, which as you age will become increasingly more difficult to re train it out of. Damge? no ? but you will call it that when at age 40 you discover that there is a 95% chance that there is now nothing you can do about it. I think it is called fixed focus/fixed range.
After working nearly 10years on electronic circuits I found I coul no longer read house numbers and many street signs. I would spend 10 - 12 hrs per day 6 days a week in a well lite work area normaly working with it 20 to 40 cm from the components.. I was told 15 years later that had I done some simple eye exercises at that time and continued with them I would still only need the specs for driving only..oh that is inspite of the fact that my eyes are now showing signs of damage from the effects of Diabetes.
My eye problems are not from CRT use, but it would be the same, except you also have problems from the excessive blue spectra, and mild x-ray exposure.
I really had to laugh at the thought that someone visioned electrons flying through the screen at them. The poor electron. But when the electron is fired at high enough potential, it will bring several of his not near so glass disabled friends Mir’s X and Gamma Ray,. and they will visit you, some entering your eyes, many checking out various parts of your upper torso and cranium.
Post Scriptum to my earlier Post:
I wish to Add Hyundai branded LCD monitors to the list.. their quality is 99% of those I have listed, and certainly better value for money.. And it seems that when I finish evaluating this 19"inch model, and place the review on my web space and blogs.. I get to keep it.. the box will be here monday right? :)
There is zero correlation between staring at a computer screen and eye condition - I am living proof. Before PC's were invented, I had 20/5 vision, meaning I could see clearly at 20 feet what most people can at 5. Since those years, I've spent anywhere from 40 to 60 hours a week in front of my computer screen, and my eyesight has zero degradation. (yes, I can shoot a flea off a cat's arse at 1000 yards with iron sights.)
