Do you also use computer sometimes 16 hours a day like me? :) If so, I bet most of you have a loss of eyesight that you haven’t noticed yet or already wearing prescription glasses.

Just because computer screen is too bright that you don’t notice, sometimes you begin to lose your eyesight or begin to have sleeping difficulties. There is a free software designed just for you. During the night times, it makes your screen a little bit yellow  and it will stop hurting your eyes. Then you’ll be amazed how have you been damaging your eyes for so many years.

It is called F.lux, available on all platforms for free. The only configuration I did was to enter my location and then adjust night lighting to “Fluorescent (4100K).” You’ll notice the difference after sunset and your screen will be yellow as hell (don’t worry you’ll get used to it in a few minutes). :)

It is also available for iPhone/iPad if you have a jailbroken one. Don’t forget to spread the word among your friends or sharing if you liked it!
