You also stated how to over come the problem who has vision correction. I like the black color theme in design and development sites . It can't be felt if you don't actually go through some black them site likeweb2designers.us. Thank you and awaiting next post.

And I don't think I am missing the point. Studies have shown we reed white text on black slower ... I wonder why?

Text on a screen using Dark colors is words different than light colors in a book in low light.

The fact is that your monitor is illuminated, and dark colors aren't like a lack of light in the room.

And yes, he would make the font size bigger, but you can do that too.
Hold Ctrl and press + (or rather, hold Ctrl and press equals (=) ).

If he really was doing it purely for not causing eye strain, he would make the font size bigger!

I have to prefix this by saying;
I use a computer daily, I'm in the same boat as many of the other readers, and I attempt to practice what I preach through tolerable means.

I can't believe so many people stare into a light source and then are surprised when their eyes hurt. I try to run my computer at 0 brightness, and about 50% contrast. (YMMV with regard to different models of screens).

There is a definite problem when it comes to color, much of it is washed out and you lose some detail. It's a small problem, and I think the point I'm at is a good blend of acceptable color tone, but not blinding bright.

I cry whenever I see a monitor at damn near 100%/100% settings. It's sticking out like the local sun for the room/office/whatever.

Just as the author of this post said, you don't stare at a light bulb, you don't stare at the sun, so don't stare at a computer screen which is turned all the way up. The only time your face should be white washed is if there are no lights on (not to mention, you probably shouldn't use the computer too much with the lights off, that's even worse...).

The reference is an analogy, that bright light, and the inability to focus, can damage optical vision, either which may or may not be repairable.

Our eyes have little problem focusing on most printed material, which is characterized by dense black characters with well-defined edges. Healthy eyes can easily maintain focus on the printed page. Characters on a computer screen, however, don't have this contrast or well-defined edges. These characters (pixels) are brightest at the center and diminish in intensity toward their edges. This makes it very difficult for our eyes to maintain focus and remain fixed onto these images. Instead our eyes drift out to a point called the "resting point of accommodation" or RPA.

Our eyes involuntarily move to the RPA, and then strain to regain focus on the screen. This continuous flexing of the eyes' focusing muscles creates fatigue and the burning, tired-eyes feeling that is so common after long hours at the computer.

Yes, having the monitor being brighter than the environment contributes to eyestrain -- that is why it is recommended that you do not watch television or use a monitor in a completely darkened room.

*However,* all of this does not mean that looking at a monitor is, in any way, like looking at the sun. Looking at the sun will burn your retina, which no corrective lenses can fix. Eye strain and the ability to focus is a different thing entirely.

In the last couple of years I was diagnosed with myasthenia gravis, a neuro-muscular disease. MG invariably affects muscles in the eyes. I am pretty sensitive to light at times and very much prefer light on dark.

Beryl with Super-n to switch to a negative of a page is huge help.

I would like to know how paper ended up white, I have always assumed it was just a matter of what was easier to create dark inks to mark light paper. I would be surprised if it was done for ergonomic regions.

However, judging by the comments some people have a strong preference for dark on light.

So lets have more of the beryl magic.

normally, i don't engage in discussions like this but since you are saying:

The reason was based solely on my health, and the health of you.

i took it somewhat personally.

frankly, you are wrong, and AnonymousCoward is right: black on white is better for reading than white on black. he/she even attached some very good urls.

and

and I don’t think I need to cite sources,

yes, you don't have to publish your sources but it's a good habit to do so in order to transparently show where your ideas are comming from to receive an insightful critique - we all are searching for *a* truth, right?

ps: and the reason why books are printed black on white and not the other way around is because it's cheaper.

pps: that example with photographs is just ridiculous - you read/recognize slower because it is more difficult to.

no offense, though.

best regards,

another anonymous covard

However, your point is based on conformity. "Because everyone else is jumping off a cliff, you should too" isn't exactly the attitude that I lead in life.

Lighter text on darker backgrounds is better on the eyes, so as such, I am taking a stand with my website to improve your eye care. With this knowledge that you now have, you can do with it as you will. What you should do, is make your desktop darker, and encourage websites to do the same.

Conformity for me, just because everyone else is doing it, just isn't an option.

White on black is much harder to read, especially if you are older and using spectacles.

Hmm.. this actually isn't true. Too much luminance is actually a problem for some older users and too big of font isn't all that great either.

The only problem I can see with the design of this website is that the contrast between the dark gray background and light gray text is a little low, combined with font which by default is a little small. Font size is still a bit tricky, because it shouldn't be huge either. Fonts which are too big do not show as much content on the screen which effect readability and understanding.

If you were really interested in keeping a black theme, you could tweak the contrast a little and maybe bump up the font size a notch -- or just let people read it via RSS (which is probably 80% of your traffic anyway 🙂

What is far more damaging than a very bright screen is quick transitions between a very dark screen, and a bright one. The pupil needs to dilate or contract too quickly, and this causes _severe_ strain after time. A quick analogy is going for a sprint without a warmup or without jogging first.

Your website is black -- great. My desktop is white and the vast majority of others' are too. In this scenario, having your site open in a browser at full screen, then going to another page is extremely problematic and -- over time -- harmful to your eyes.

I'm not trying to say a fully white background is good -- quite the contrary. The ideal background is just off-white, to reduce glare.

Basically, on Windows, you put the following in C:\Documents and Settings\Username\Application Data\Mozilla\Firefox\Profiles\something.default\chrome\userContent.css
And on Linux I'm sure it's something like..
~/.Mozilla/Firefox/Profiles/something.default/Chrome/userContent.css

Or, with a slightly less long path, use an Firefox extension like Stylish : https://addons.mozilla.org/en-US/firefox/addon/2108

Then, go to the end of your userContent.css file, and paste :

/* Start of http://www.pthree.org black-on-white theme */
@namespace url(http://www.w3.org/1999/xhtml);
@-moz-document domain("pthree.org"), domain("www.pthree.org")
{

blockquote
{
background-color:#999999 !important;
}

.main {

}

.post h1 a

}

.post h1 a:hover
{
color:#333333 !important;
}

#commentsform
{
background: #999999;
}
}

/* End of http://www.pthree.org black-on-white theme */

Like I said, not perfect, but it makes the main post and comments look decent, everything else stays as it is (The comment preview area looks a little odd, but it's still usable)

You're right, we are looking at a big light bulb (monitor) for many hours.
The black text on white paper is easier to read becouse on paper, we are looking at reflected light, the paper is not the source of the light but it reflects it. But the computer monitor is the source of the light.
And it's easier to produce good contrasted black text on white paper than using black paper and white ink. That's why most of the printed mediums are black text on white paper.

Besides, your theme isn't light on dark. It's low contrast gray on gray. I'm not telling you to change, but don't kid yourself, your theme isn't the most readable possible.

Another advantage to Opera is that if you zoom in or out of a page (using just the + or - key), not only the text zooms, but also the images and often Flash objects as well. zoom ranges from 20% to 1000% of the original size and returning to the default zoom amount (100%, but this amount can be set differently in the config) is as easy as hitting numpad *.
And let's not forget the exellent built-in RSS reader that Opera has.

By default it is the ultimate toolbox for surfing the web, reading RSS feeds, mail, news, and whatnot.
In short, i would be lost without Opera.

I also understand though, that this isn't ideal for everyone. I think Firefox should include more accessibility features, and be able to detect when light text is on a dark background, and prompt the user to invert it.

Personally, for me, white text on dark background is actually easier to read. Especially with a low-contrast setup like yours (it's not white vs black, it's a dark shade of white and a light shade of black)
