For yachtsmen who have struggled to use a PC at the chart table on a night time passage, with the glare of the screen ruining your night vision, then this simple and free piece of software is what you need.

Called Pango Bright, it allows additional dimming of the main and secondary monitor beyond what you can achieve with the normal screen brightness control of the laptop or monitor. Select from 100% down to 20% brightness and you will immediately bring a welcome relief to your tired retinas !
