What do monitor backlights have to do with bias lighting? And how does it help your eyes? Let's find out...

Script:
00:00:00.080 bias lighting basically means just
00:00:01.920 having a light behind your screen and
00:00:03.760 the reason this is good is because when
00:00:05.440 you're looking at a screen in a dark
00:00:07.040 room your eyes are forced to adjust your
00:00:09.000 vision to clearly see the screen think
00:00:11.080 about when you use a camera in a darker
00:00:12.960 environment and you point it at
00:00:14.519 something very bright all you can see is
00:00:16.359 a blinding blob of light however if you
00:00:18.640 set the camera to focus on the bright
00:00:20.800 light it then gets a lot clearer and the
00:00:22.760 rest of the room gets a lot darker this
00:00:24.519 is exactly what our eyes have to do
00:00:26.199 while watching a bright screen in a dark
00:00:28.039 room as you may be able to guess this is
00:00:30.080 very difficult on our eyes and doing it
00:00:32.200 for long periods of time can lead to eye
00:00:34.079 strain however when you put a light
00:00:35.879 behind your screen your eyes don't have
00:00:37.840 to do as much adjusting since there's
00:00:39.640 more light in the room not to mention
00:00:41.360 that there's not a sudden blinding flash
00:00:43.120 of light when it changes from a darker
00:00:45.000 to a brighter scene
