Sunglasses is a Google Chrome extension I wrote that tints all the webpages in your browser window. It bothered me that webpages with white backgrounds were too bright as compared to the darker terminal windows that I was coding in. Turning down the brightness on my screen would render my terminal too dark, but turning up the brightness would make viewing webpages with a lot of white hurt my eyes.
Sunglasses puts a small sunglasses icon (designed by Caleb Hou) just to the right of the location bar. Clicking it pops up a slider that you can set what darkness you want your webpages. Saving sets the darkness for all tabs in a window. You might have to restart your browser for all changes to take effect, but installing the extension doesn’t force you to.
