blue light blockers

ok cool, that makes sense for sure. So at night it would be advisable to get the IR bulbs, or just use candle light when possible.

I've also read that it's not just the eyes but the skin that absorbs the light, so when exposing to sunlight it's good to get as much skin as possible, and at night or when under artificial light it's best to cover as much of the skin as you can. I'm pretty sure it was one of Jack Kruse's articles but I can't seem to to find it at the moment. I have been trialing doing this at work, since I'm in a TV studio most of the day under very strong artificial light, I make sure I roll down my sleeves to cover my arms and wear long pants, all I need now is some lenses to block the the lights without looking like an idiot and freaking out the students haha.

I've also taken to having my morning salt water and smoke looking at the sun (not directly) but getting that good light in the eyes to set my circadian rhythm, I must admit since I started doing it around 6 months ago I have noticed better sleep and being more alert in the morning, which is especially something new for me, I've never been a morning person.

Don't count the Incandescent light bulb out yet since it produces a near ideal spectrum:

You need to have your skin exposed to the sun and the most important part is your eyes.

Pay attention to light and dark cycles. Make sure you eat a lot of seafood and DHA. Make sure you drink a lot of spring water. And then get a lot of UV light through your eyes and skin the days that you can and block the light at night, utilizing glasses with Blu-Tech lenses. Or even Uvex glasses. It's really not that hard

So if you get AM full spectrum sunlight and block blues at night and block blues any time you're indoors, you have basically probably got 90% of the problem licked. Here's the key part. This is the part specifically you asked me about. The more blue light toxic or blue light hazards that you have faced in your entire life, the more DHA you need.

I think about chromophore cells and I remember Gaby saying not having any light, even LED from computer at night in your bedroom. But I couldn't find the article in SOTT.

For my work, on computer I took these glasses from my brother :

15% blue-light blocking. It's good for half a day, more and I get mind excitation.

I eventually developed big problem with eye strain from sitting at a computer all day and I had some glasses for use with reading. Sometimes I'd use them at the computer, but not very much. The strain got to the point that my eyes hurt so much I couldn't sit in front of the computer so I started using the glasses, that helped for a while. The glasses were Ok, they helped with the strain, but later even with those glasses the strain came back and it got to the point that I thought maybe I need a new prescription since the glasses were many years old. I went to the eye doctor and did get a new prescription and at the same time I also got something called Crizal lens that have a "Smart Blue Filter" that block some UV light. That helps a bunch! They cost more, health is priceless though ;)

I also recently started using this little tool on my computer, it changes the screen settings based on the time of the day, that seems to be helpful too:

Another thing to think about when you are at a a computer all day is the type of screen you use. If possible it may be worth getting an OLED screen.

LCD versus LED screens – which is better?

This is one of those questions that anyone buying a new TV asks but most people are unaware that it’s a misleading question. Technology manufacturers like to draw an artificial distinction between their LED and LCD monitors. This cons us into believing that the LCD has been superseded by the LED, when in actual fact all that’s changed is the way the LCD monitor is backlit.

LCD (liquid crystal display) technology – to the uninitiated – involves sandwiching a liquid layer between two layers of glass and backlighting it. Older technologies backlit the screen using fluorescent light – called CCFL (or cold cathode fluorescent light). This produced light across all parts of the spectrum, with the peak in the green light part of the spectrum

More modern computers still use LCD screens but the backlighting used is more often LED (light emitting diode) technology. This has many advantages over the older fluorescent light technology. It provides a thinner, lighter and more energy efficient display – generating less heat and consuming less power. However, the LED light spectrum is very different to the older fluorescent technology and emits a lot more light from the blue-violet end of the spectrum

Particularly disruptive has been the recent widespread adoption of digital screen devices backlit with Light Emitting Diodes (LEDs) which emit blue light with particularly high intensity. The good news is that a new lighting technology called Organic Light Emitting Diode (OLED) is coming out. It is still expensive, but certain types of OLEDs may emit blue light of similarly low intensity as candles.

An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. This layer of organic semiconductor is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as mobile phones, handheld game consoles and PDAs. A major area of research is the development of white OLED devices for use in solid-state lighting applications.[1][2][3]

There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell (LEC) which has a slightly different mode of operation. OLED displays can use either passive-matrix (PMOLED) or active-matrix (AMOLED) addressing schemes. Active-matrix OLEDs (AMOLED) require a thin-film transistor backplane to switch each individual pixel on or off, but allow for higher resolution and larger display sizes.

An OLED display works without a backlight; thus, it can display deep black levels and can be thinner and lighter than a liquid crystal display (LCD). In low ambient light conditions (such as a dark room), an OLED screen can achieve a higher contrast ratio than an LCD, regardless of whether the LCD uses cold cathode fluorescent lamps or an LED backlight.

There is a really nice little piece of software which does the job (filtering out the blue light of computer screens, after sunset or even during daylight) : "F.lux" - and it's free (contributions recommanded). Works on Windows, MacOS, and others...
_https://justgetflux.com/

Thanks for reminding me of this Bastian, I had it on a previous computer and forgot to load it on my new computer, so now it's done.

I have this Himalayan salt lamp I bought a little while ago which is the only light I use after sun down (for the most part). It's very dim and has a pinkish, orangey yellow glow to it that I find very soothing - puts me to sleep right away!.

This sounds like a very nice muted light to have instead of my table lamp, with health benefits too. I have bookmarked a site in OZ.

I definately need to reduce harsh lighting in my home, as it affects my eyes and my sleep quality. I do turn off my modem every night and my computer is hooked up via ethernet cable. Also my bedroom consists of only a very small radio alarm, which I need for early morning calls. Mobiles are left in the loungeroom, so I have made a few improvements.

It's not free and the pricing model is a bit strange.

I’ve been using the Iris program for about a month now. Ben Greenfield did an interview with the creator of the program: _https://bengreenfieldfitness.com/2016/09/what-is-the-healthiest-computer-monitor/

So far I like it better than f.lux. I’ve been spending more time on the computer with less eye strain. The Iris program lets you set the color temperature much lower than f.lux. I have it set at 1700, even during the day.

The pricing is a little weird, but it’s not very expensive. I paid $2 about a month ago, and my available time remaining shows 149 days.

Apart from the above, grounding also plays a role in what he recommends for staying healthy.

Thx ! That's also what they advice here :

_http://guardianlv.com/2013/05/nasa-confirms-super-human-abilities-gained/

Remember, it’s 10 seconds the first day, at sunrise or sunset, adding 10 seconds per day each day there after. After 90 days of accumulative gazing equaling 44 minutes, you cease the gazing and start the barefoot walking 45 minutes per day for 6 days. At this point, I could imagine, hey – if you made it this far, what’s a year of barefoot walking an hour per day to keep it all? You will have to try it out and see for yourself.

My experiments gives me two things : lightness and stability : eat the sun, connect to the earth.

I sort of understand the electromagnetic spectrum. But I'm wondering if you simply take a red or orange sheet of transparent plastic and put it over an LCD screen (or any screen), does that essentially block all of the blue light and convert it to red/orange? Would it actually be effective in making the light emitted healthier?

There are a few on the market already for your phones, tablets and computer screens. I haven't looked into the science behind them, but I assume they will be similar to using F.lux or Iris _https://www.ocushield.com/ _http://www.fiara.com.au/shop/pc-monitor-anti-blue-light-filter/

Thanks, I thought it would be as simple as just putting a colored piece of plastic over the screen. But there are actual products called "blue light filters", that remove the UV and violet end of the spectrum.

 

[987baz]

This is a long article but worth the read if you want to understand the light spectrum better, it also has a way to make your own blueblockers at the end.

It compared 3 of the most used blueblockers and gives a rundown of what frequencies they actually block. See attachment for one of the comparisons
