Is all the white energy from monitors causing any damage to peoples sight over long term periods?

what is the average all that white energy as lux, how would you measure it?

a lot of web pages have white backgrounds which I think make it hard to read, webpages have emitted white light coming into your eyes at the same time white reading the pages content

there is a difference between lux levels for reflected light on paper for reading and emitted light from screens for reading

it is as simple as getting a lux meter and pointing it out the monitor or is there a better way of finding out what amount of lux is being emitted at you?

how could the lux levels be averaged out over a whole day? video recording web pages?

I know there are stylish scripts which can change the web pages color defaults to a users choice

this site has a black background for reading, while the editing window has a white background

popurls has a black background

http://popurls.com/

it has an aqua colored font on black background

I looked up its rgb figure 139,187, 201

Does it have higher readability friendliness than white background websites?

“Our” is the easiest to read, don’t know white letters on a black background isn’t used my widely.

you dont find black pages with white text used on paper very much with reflected light

you will find the opposite on the emitted screen with black background on white text and / or black text on a white background / or gray/colors options

I’m asking which one in general is a preferred option

You should get your light meter and measure the ambient light outside on a sunny day. Or eve on a dull day. It is waaaay more than you will ever get from looking at a computer monitor.

And what is White Energy?

Stew.

I’m not going to type that all out again just to put it in the right thread.

The latest firefox allows you to override the colours specified on any webpage and have (eg) white text on a black background.

the thing that destroys eyes is maintains a fixed distance between eye lens and screen, not to mention that screens are more often than not TOO small for the human eye and thus fix the eyeball in one position

what interests me it how much energy from monitors the eyes are receiving and does that lead to any eye damage

I think a gray or black background with white text would produce less energy

one experiment I did was to get the screen completely as black as possible then change to a white only screen in a dark room to see the differences

a screen that is turned on but is totally black is still emitting an amount of light

did you know that a bright screen and dark surroundings can cause eye strain

any source of light that’s still direct in your vision and is significantly brighter than surroundings caused eye strain

eye strain is caused by differences in light levels between areas

How does that relate to people’s eye health in movie cinemas where there is a bright screen and dark surroundings?

it’s not good for your eyes , it strains them

For people in very flat areas, they would have a lot more brightness near the horizon

much different to that of people living in a shading forest

As you get older your night vision is one of the first things to go.
Don’t know if it is a vitamin A deficiency?
WTF is it with old people and these wrap around black sunglasses, they look terrible and just scream ‘ken old old old.

Looks like I need to repeat myself. No computer screen can in any way compete with the amount of light you get outside from the sun. So people these days are receiving less light to the eyeball over a lifetime than outdoor workers, or even people in history before electric light in houses.

There is no evidence that looking at screens damages eyes. I was there a the beginning in the 1980s when computers started to be put into offices. Just like trains and cars were going to destroy the human body because they couldn’t cope with the speed, computer screens have shown to be non damaging.

Now, what you see and do on the screen, that might turn your brain to mush, but your eyes are fine.

the body stops producing as much acid to break down food

less vitamins gained from food affect the entire body

take multivitamins

they cover the crow’s feet pwm.

ever tried reading a book with a beam of sunlight on its pages in a darkened room

it’s the difference in light levels that cause eye strain

>As you get older your night vision is one of the first things to go.<<

I’ll tell you a story. Over your lifetime, the lens inside your eye goes from being clear like water to being dark brown like a sunglass lens. This is cataract. Yellowing is evident from middle age. There are also small defects in the structure. The effect is to scatter light a it goes into the eye. In bright light this makes veiling glare. At night it scatters the little available light and less of it focusses on the macula, degrading your ability to make out detail.

None of this is unusual or unnatural.

Damned annoying, though.

the way that differing light levels in industrial situations has been known for at least 60- 70 years

see that single light source in your room?

it’s a bad way to light your rooms

people who design and build houses don’t understand how the human body works in their profuct

the theory I’ve got that will win me the Nobel prize is that eye movement keep’s and helps blood and fluids pumping around the eye

as the eye stops moving around as much as in a natural environment blood vessels die off

Dear, oh, dear.

Yes but. But because the iris compensates, it’s sometimes the contrast that is the problem. For me, the worst harm was staring into car headlights while sitting waiting for buses on a crest. Not every car headlight, just the brightest 5%. Because of the contrast the iris couldn’t adjust.

At night, I like to have a room light on while using the computer (or TV) to reduce the contrast.

As a simple rule, if looking at it doesn’t cause pain then it doesn’t cause damage.

I thought continual focus on a point the same distance away was bad for your eyes, and has been linked to short sightedness?

/* Looks like I need to repeat myself. No computer screen can in any way compete with the amount of light you get outside from the sun. */

Even for the SSSF nerds / trolls who spend 23h59m59s indoors staring at the screen, and 00h00m01s outside in the sun?

and 00h00m01s outside in the sun?

damn alex skewing the results.
