Eyestrain, Computers, The 20 -20–20 rule, Light bulb APIs
The 20–20–20 rule:
- Every 20 minutes, look at something at least 20ft (6.09m) away, for at least like 20 seconds.
Computer glasses (to reduce glare and eyestrain):
- gaming glasses (e.g. the Gunnar tint and coating (http://www.gunnars.com/faq/) can be found at e.g. Best Buy (where they are known to carry e.g. Gunnar Intercept computer gaming eyewear glasses frames))
- safety glasses (can often buy in bulk)
- nosepads (replaceable)
- nosepads (built-in)
- glasses measurements (mm)
- temple measurement
- vertical/frame height
- eye_size*2 + bridge size ~= width
Monitor adjustments (to reduce glare and eyestrain):
- brightness/contrast
- lighten the blue channel (*)
- good monitor stands support vertical tilt
Tools that gradually modify monitor settings to match the natural solar cycle:
- f.lux (http://justgetflux.com) — Linux, Mac, Windows, iOS
- Twilight (https://play.google.com/store/apps/details?id=com.urbandroid.lux) — Android
Browser extensions for modifying brightness, contrast, background, text color; inverting just the CSS colors:
- [Deluminate, Stylish (userstyles.org), High Contrast] — https://westurner.org/tools/#browser-extensions
- Disadvantages: (1) These sometimes cause hiccups (easily diagnosable by unchecking the extension(s) and CTRL-R refreshing the current tab) (2) If the browser colors are inverted AND the whole screen is inverted, there’s probably a less contrasty CSS styleset
System High Contrast / Color Inversion:
- “settings” > “appearance” / “accessibility”
- Compiz color filters (e.g. negative-red, negative-red-dim https://github.com/westurner/dotfiles/tree/master/etc/compiz/colorfilters)
- xgamma, xbacklight, xrandr, xflux (e.g. https://github.com/westurner/dotfiles/blob/master/etc/i3/config)
Dark Window Manager themes:
- Windows: WindowBlinds, Win7+
- Ubuntu 10.04+
- Gnome 3: [dnf install -y] gnome-tweak-tool > “Appearance” > ”Global dark theme”
- OSX 10.10 Yosemite “Dark Mode”
*[Blue] Light affects sleep (/alertness):
[…] experimental research suggests that an average person reading on a tablet for a couple hours before bed may find that their sleep is delayed by about an hour. — https://justgetflux.com/research.html
- Complementary color lenses filter the opposite wavelength(s); so lellow-ish lenses block blue light.
- Probably because the ocean sounds.
- [I think] red light is easier to accommodate to in the dark.
