Blue light with a wavelength of 380 nm to 495 nm out of visible light emitted from an LED display mounted on a personal computer, smartphone, etc. is called blue light, but since it reaches the retina of the eye, it damages the retina It is said that there is a case to give. To protect your eyes from such blue lightPC glassesAlthough attention is drawing attention, I actually tried using the color temperature adjustment software "f.lux" that cuts the blue light emitted from the PC just by installing it.

F.lux has been updated to a new version

Then, it is possible to select the color taste mode of the screen according to the situation.

The Settings screen looks something like this


Two slide bars extending to the left and right are for the upper color temperature during the day and the lower one to set the color temperature at night. Color temperature can be set from 2700K to 6500K.


In "SET YOUR LOCATION" 2 you can set your whereabouts and click "Change" to set the location.
