Seriously, Nestle? There’s no way this makes any real difference : fucknestle

The majority of the research out there does not support dark mode being better for your eyes. Generally, you only experience additional eye strain from a screen when the brightness of the screen is different from surrounding light conditions. So if you want to reduce strain, use brighter screens in bright daylight and dimmer screens in a dark room.

However, the research also indicates that it is easier for most people to focus on text when it is dark text on a light background. This is especially true for people with astigmatism (about 1/3 of Americans).

So, kindly leave your default dark mode off my sites. Thanks.

But the first comment was in all caps, so I don't know who to believe

[-] Frozengyro@lemmy.world 32 points 10 months ago

Or people should have an option.

[-] constantturtleaction@lemmy.world 6 points 10 months ago

True. Updated the last sentence of my comment slightly. I suspect most people who use the Internet are not basement dwelling trolls and therefore probably are typically in brighter surroundings.

[-] PixxlMan@lemmy.world 16 points 10 months ago

I love dark mode, but this is right.

[-] dgriffith@aussie.zone 4 points 10 months ago

Loved the old amber screen VT220 terminals.

Amber on dark grey inactive phosphor (or dark amber depending on how you fiddled with the brightness).

I wonder how much OLED and "true black" displays have contributed to eye strain in recent times. Bright text and absolute black display might be good for vision/clarity but is it good for long term use?

Doesn't paper reflect light when it's white? If it absorbed it, it'd appear black.

[-] jarfil@lemmy.world 29 points 10 months ago* (last edited 10 months ago)

Paper reflects light for white, ink absorbs light for black.

OLED and CRT screens stay off for black, use power for light.

LCD screens keep the backlight on all the time, only hide it for color/black.

E-ink works like paper... but has low refresh rates and the displays tend to break somewhat easily.

If we all used dark mode on OLED screens, we could save maybe 0.0000001% of energy, making everything "more sustainable".

[-] admiralteal@kbin.social 15 points 10 months ago

LCDs do not stay off for black. LCDs fill the entire back with bright white light and then shutter off pixels to make them black. The energy used between displaying white (the backlight) and displaying black is basically the same.

OLED is a bit more complex.

There's no difference between the light reflected off a page or emitted from a screen. It's all photons stimulating cells in your eyes. Your eyes are fucked up because you're getting older.

[-] Kelsenellenelvial@lemmy.ca 7 points 10 months ago

Paper vs display at same intensity and colour, sure. But there’s other differences like actual brightness, contrast ratios, colour temperature, etc. which can have subtle effects. I believe one of the biggest issues in terms of eye strain is when you have a display that’s brighter than the surrounding area, and lower contrast/resolution. I feel like the benefit of dark mode is less about the total light emitted, but when the brightness is from the text instead of the blank area around the text it’s more readable because you’re not trying to read through the glare of the background.

Your first mistake towards sustainability is visiting Nestle in the first place. That company's existence is the opposite of sustainability.

[-] DavidGarcia@feddit.nl 50 points 10 months ago

According to a Purdue University Study dark mode can save 3 to 9% of your battery if you're on auto brightness. Let's say your average phone uses 15Wh per day (5.475 kWh per year). Let's say 5 billion people use smartphones. That's around 30 TWh for total yearly smartphone consumption.

So if everyone was using dark mode, it could save around 0.8 to 2.5 TWh a year in the best case scenario. But that is if everything on your phone was dark mode. Not sure how much time people spend browsing websites percentually.

That's around 0.1 to 2.7 times the daily electric energy production of all nuclear power plants.

The world electricity production is around 23000 TWh per year, so you could save around 0.0036% to 0.01% of yearly energy consumption by switching everyone to dark mode.

Such impactful, much environment, wow

Now calculate how many nestle wells that steal people's water that makes.

that study talks about oled displays btw, shit's not gonna change for regular backlit devices

word of the day is greenwashing, fucking engrave it into your brain -- get the words for the phenomena and all that shit

[-] Kushan@lemmy.world 6 points 10 months ago

Fuck Nestlé, but technically they are right - it saves a little bit of energy and that's not a bad thing.

Yes, it's a drop in the ocean compared to the amount of energy we produce and no doubt there's better ways to save energy but heck, I'm down for doing the little things too.

Besides, it might encourage others to offer dark mode and that's no bad thing.

Again, I reiterate my opening statement: fuck Nestlé.

So would not visiting nestle.com in the first place.

[-] totallynotarobot@lemmy.world 15 points 10 months ago

This is true, good point. Avoiding nestle is a more sustainable experience for life on earth.

On devices with OLED screens, the more pixels on the screen are lit up, the more power the screen consumes. So on the majority of smart phones these days, dark mode will slightly reduce energy consumption. Devices with LCD screens will likely show no difference, and we're talking a fairly negligible amount of power here anyway.

[-] PieMePlenty@lemmy.world 14 points 10 months ago

So you are saying nestle could contribute more by not using child labour in African cocoa plantations?

[-] filcuk@lemmy.zip 7 points 10 months ago

No, just turn your screen brightness down

Not if Dark=Grey like on the screenshot. Needs to be proper black.

[-] trebuchet@lemmy.ml 17 points 10 months ago

That's absolutely not true. OLED pixel energy usage is proportional to the amount of light they need to emit. Dark gray is essentially the same as black in terms of energy usage.

[-] captain_aggravated@sh.itjust.works 7 points 10 months ago

Not exactly. Yes dark grey will consume more power than full on "the pixel is turned off" black but it does take less energy to show a dark grey screen than a bright white one.

[-] SideshowBoz@lemmy.world 22 points 10 months ago

Lmao, says company that literally dries out local aquifers and puts that water in plastic bottles…but dArK ModE 🫠

[-] Treczoks@lemmy.world 20 points 10 months ago

Advertising and corporate messaging are not about being right, but only about appearing right to a sufficient number of people.

[-] Turun@feddit.de 17 points 10 months ago

On OLED screens dark mode does actually save power. My phone switches to dark mode when I turn on battery saving mode.

It probably doesn't matter much in the grand theme of this, but let's keep the criticism factual. God knows you don't need to make up arguments to criticize Nestle.

[-] Delphia@lemmy.world 28 points 10 months ago

Yeah its not that you (and Nestle) arent right, its that its such a pissingly small amount of energy even on a global scale to be laughable.

Like "Nestle, you arent wrong. You're just an asshole"

[-] Oliper202020@lemmy.world 8 points 10 months ago

It doesnt really matter when its just a gray theme and not black then on oled the pixels are still on

[-] jarfil@lemmy.world 5 points 10 months ago

They still use less power for gray than for full white... so it's "something".

It doesn't, but Nestlé's CEO probably thinks he can use this as an excuse to enter through the Pearly Gates rather than get tossed into the pit that's reserved for him in Hell.

What's up with giant corporations and guilt tripping people into switching to dark mode? I've heard win11 does this as well.

[-] Dmian@lemmy.world 15 points 10 months ago

They need to shift blame on consumers and their marketing departments have not much to work with, so probably this is one of their best ideas.

It's pure marketing.

It's a trend, so the marketing goblins follow it.

Guess what? Cycling dark mode results in over 300 requests to nestle servers, so it does use power sending all those requests
