How harmful is laptop's lcd screen for ur eyes?

Don't know if it's the right forum for this question or not, so please forgive me. I have an inspiron 1520 laptop with 1280*800 matte screen. I was born with a vision deficiency in my left eye, it didn't seem to get any worse over the years, and i'm wondering if my laptop's screen is really bad for both my eyes, if i use it regularly for 3+ hours every day.

Thank you,

Staring at anything for 3+ hours a day is bad for your eyes.

 

1280 x 800 @ 15.4" is quite big and should not cause problems unless the backlight is dim. Avoid sitting with your back to a window or bright light.

LCDs are much easier on the eyes than the older CRT displays because of the sharp and steady image without any flicker. Some of the CRT displays of more than 5 years ago could be quite hard on the eyes because of poor definition and flicker.

For a good answer to this question because you already have a eye condition. A M.D. would be the best to consult since none of us know anything about your eye condition.

 

Well I can't give a legitimate medical opinion on this but if yo feel any strain or discomfort you may want to ease off a bit or even increase or decrease the brightness of the screen accordingly to suit. As john ratsey said also lcds are way easier on the eyes than older CRTs anyway.

 

The general consensus is that LCDs are easier on the eyes. In terms of ergonomics, this is why many companies are replacing old screens with LCDs, in addition to the power savings they provide, but that's a different story.

While nobody can guarantee that an LCD will be easier for you, it definately is better for me. I switched to LCD 6 years ago and will never switch back to CRT.

 

should not really hurt your eyes aslong as its viewed in the right enviroment. The worst thing to do is view a screen in the dark.

 

Why would viewing lcd in the dark be bad for eyes ?

 

Wearetheborg, I would guess it has something to do with the pupil having to readjust to often they do say the same thing about watching TV and it is also true for CRT. When I stare at the screen and then look away my pupil has make a major change in the amount of light it lets in then the reverse when I look back. Ever been outside on a bright day and go indoors and it takes a few minutes b/4 it stops looking very very dark, or the opposite, going from dark to light, that second one just hurts.

 

You may want to take a few minutes to look at something further away every hour or so. That will help ease the eye strain that you can experience while staring at a computer screen for extended periods of time.

I know it's much easier said than done--especially if you have a lot of work to get done.

Nice find wearetheborg, but before I do a “context reply” just for the record I watch TV in the dark, I use my computer in the dark so I clearly experience no ill effect (headaches, eye strain) and am not concerned.

The question your quote is responding to is here and quoted below.

The person asked a specific question about damage caused by increased exposure to radiation because dilated pupils could allow more in. The O.D. responds to that question and that question only.

Back to this NBR thread, OP said that they were born with a visual deficiency, ViciousXUSMC used the word hurt. You are the first to use the word “damage” and remember your source is talking about radiation. Since we don't know OP's condition and at least I am not a OD or MD we can't really comment to much. Some people do get eye strain and it causes things like headaches or dry/watery eyes and general discomfort. So your complete dismissal of the contribution of “being careful about the environment to view in” seems wrong. Also a site called madsci.org I believe is going to have some controversial views so when you use as a source you should be aware of that. If the OD had been asked, "when I watch TV in the dark I get headaches" OD would of likely said then don't do it. Not something like "no you don't". just my opinion.

 

Your eye has to adjust to the contrast to light and dark, I would say its a pretty well known fact that viewing a bright light source in the dark is bad for your eyes. If you want to debate it, feel free.

I watch movies and things in the dark, but my screen is so big I only see the screen and thus avoid the ill effects of dark viewing, but when you have both the dark enviroment and the bright monitor within your view at the same time thats when the problem occures.

 

You left me behind in battle bud.

I can find anything on the WEB I want. Does not solidify your point. Kind of side pointing at best. Something is not clicking! Here is my link, first one not as far back as yours.

Edit: "Eyestrain can occur when the eyes are fixed on an object for a long period of time, there is poor lighting, or there is glare,” explains John Bullough, Ph.D. My PHD trumps your little MD's and your OD to the power of ten!!!!!!!!!!!!!! MD's and OD's don't know jack about research!!!!!!!!!!!!!!

 

what about movie theaters? that is an example of viewing a bright light source in the dark.

 

Not really theaters have to meet THX standards which means that your vision is competly taken by the light source. Its way different than a small bright screen in the middle of a dark room.

Not to mention the movies is just a reflection of light rays from a projector off of a screen. Not direct light rays from a source like a TV/Monitor.

 

I have same problem with my new laptop (vostro 1500 )
i have headache and eye-ache
i want to sell my laptop but i don't know which laptop can i buy ?
pleas help me

 

Which LCD panel do you have in your Vostro 1500? (Resolution and whether glossy or matte)? Are you using the panel at its native resolution (ie the resolution in Windows matches the hardware resolution of the panel).

And maybe you need to get your eyes checked.

Im a regular at the laser eye surgeons..............marvelous thing, technology.

 

You guys bring many good points to the table that I had not thought of. But there is one aspect that seems to have been omitted. Another source of problems for your eyes is the intensity of the light emitted by the LCD screen.
The intensity is the density of energy in watts per square meter. This intensity is much higher than the intensity of natural light. About 6 years ago I got into an accident where i received trauma to my high (i reveived a hit on the eye that has haunted me ever since) One aspect that I could say is positive out of this if I could say is that this eye is now much more sensitive to light. And so when using computer screen my eye hurts.....it is like a instrument to measure the intensity of light. If there is one thing I hate its looking at those damn white pages....white light coming from the screen is the worst. For instance, I will lookaway and the pain felt in my eye will go away....as soon as my eyes starts looking at the screen again it comes back. By the way if someone knows what happened to my eye and what i can it would make me the happpiest man in the world as for now it is an obstacle to my career, me needing to read alot(I got hit on the eye by a hand that had a ring on it and now i can observe a dark spot on my left eye's vision....I consulted with a couple of doctors but they couldnt find anything....and the pain originates from that spot....im wondering if the hit scratch something on my eye globe...its like it has a natural light filter and it is broken at that spot). But to resume....the day when we can make displays with a light as natural as possible a big portion of this discomfort should go away. I remember those crt screens....that was torture for me.
