We don't need bluelight filtere

Why we actually need bluelight filters in lens, monitors and phones? Led bulbs are already emitting a hell lot brighter bluelight every day and night. Whats the point in buying these less blue marketed gadgets

Buying? I'm not paying for blue light filters, they come with the devices.

You are paying for the device. And there are dedicated computer glasses for blue light filtering

Yes but I don't buy those glasses. And as for useless features devices come with: there are scores that everyone pays for but never uses. For instance: Windows 11 has a feature that let's you control RGB backlight of your computer components.

Imagine if everyone got their devices and software tailored to their specific needs. The cost for the developers would be so much higher and they'd never develop anything actually useful for the majority of users.

Take Windows. An OS is a very complex piece of software that has tons of features. One of them is coincidentally a blue light filter called Night Light. Microsoft listens to input from the community to add these features, they don't unilaterally decide it gets in and users just get it because they pay for it.

And if you feel like Windows is too bloated with features you don't want, you don't have to pay for it. You can get any Linux distro for free and you know what? Some of them come with blue light filters. But even then, your computer monitor will likely have a colour tone called Warm, which is a lot less heavy on the blue.

Why would I spend 600-1000 on another pair of glasses if I can just turn on the night mode instead?

You have blue LED bulbs in your ceiling? Weird color to use for your home lighting but hey, if that works for you...

An article came out last month or sometime relatively recently that basically says blue light filtering doesn't help jack.

Personally I prefer warm toned light in everything except my computer monitor.

Edit: published study AND summary article. I only read the article but there is a published study associated with it.

Yep, turns out that while there is a subjective comfort benefit, there is no medical effect to it. Still worth it of course as far as just feeling nicer to use / be around goes, but also means there's no use spending money on a solution for it.

I'm not sure about the glasses, but I love to crank the orange filter up on all my devices, desktop included. It just feels easier on my eyes I suppose, but I wouldn't say I do it to help my sleep. The same goes for bulbs, I tend to prefer warmer colors.

i actually use 'night light' mode all the time now at home and at the office, except when editing images or video (and am specifically messing with color)... even on the tv for most viewing (it doesn't have a mode for it but i made a preset that tries to mimic the effect).

i can't adjust my phone but it's a flipper and i don't do sms or email on it, so the screen is hardly used.

Most bulbs are generally already warmer colours and not white.

You usually don't look directly at them up close either.

Maybe you live in a cooler area

I have night light turned on 24/7 on all my devices. If I don't I get a headache after around a day.

In fact, I couldn't consistently use linux until recently because only the latest Nvidia drivers (545) added support for night light on wayland. Those glasses could've been handy there.

My prescription eyeglasses have a blue light filter built in, and I still use night shift at night--whether it makes any difference to sleep is up for debate, but overall it's just more comfortable to use I think!

Btw unless your glasses are actually amber colored, they're not doing anything.

I had an option to get blue light filtering glasses for like $5 extra, didn't see much different when using them but I did notice the lenses turned a little bit yellow from the sun after a few years unlike previous similar glasses.
