• 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.

Features for Multicolor LED [Bluetooth] light bulbs:

• adjustable (spectrum; millions of colors)
• gradual wake-up alarmable (n min)
• gradual dim (~30min)

I had fissured open the shell by way of a handy screwdriver and exposed the shiny, mysterious world within.

The damage made to the scarred plastic molding of my Fisher Price tape recorder could never be repaired, but this fact held no importance – I was in. Finally the fruition of my careful plans and painful execution left me in longtime sandy-haired neighbor’s domicile armed with a grocery sack loaded with a prying bar and Toy Story Woody’s oration amplification system.

For years – probably closer to months, as I had lived only 4 years prior to the incident – the color-coded buttons and frightfully plain exterior of My First Recorder had tantalized my curious mind; but I knew the real magic was inside.

Mom and Dad anticipated my probing instincts, and warned me not to destroy my toys, but the force that drew me to the innards of things overpowered their stern warnings. I hid the bag of goodies carefully between the bushes outside my bedroom window and waited for my chance.

Precisely on schedule, Mom came in fitted with only the heartiest of nap-time books, and commenced reading. At the first signs of her drooping eyelids, mine glued shut while I lay behind them, waiting for my chance. A quick peek out of an eye confirmed my timing, and I tiptoed into the kitchen, scrawled my and my neighbor’s name on the closest piece of paper with the closest Crayon, and out the door I went. Five painful minutes later my investigation began in frustration for I had brought the wrong type of screwdriver – but I continued, full of apprehension for what was inside.

The first week of being grounded turned out to not be that bad. I focused on constructive activities like dusting duty and shoe tying.

Truthfully though, the hundreds of screws and twirling pieces hardly held my attention for more than half an hour, but the experience and memory significantly help define who I am.
