Reading a bright screen at night is not very pleasant. The Hacker Vision is an extension of it Chrome that changes Colour on very bright sites.
Just make one installation in the extension and this in itself will change the bright color of the web pages you visit in black. This will make it easier for you to read texts at night.
You can set up Hacker Vision simply by pressing a button to stop it mode of any time, or work only for selected websites.
You can find it here. (do not forget, it's a Chrome extension)
