Hello all,
I have been asked by a collegue about the use of a blue light filter on their computer screen, and if it would be appropriate as they are concerned about damage to the eye. Having done a little bit of reading online it seems there is some evidence (although not in humans) of tests showing that blue light from this sort of media can cause damage. However I have some concerns that the filter may make the screen too dark, resulting in eye strain and musculoskeletal issues from leaning in and thus resulting in poor DSE posture.
I'm also aware that once purchased (even on a trial basis) suddnely everyone will want one.
The posturite website references some work conducted on this with City University London. I was wondering if anyone had any experience with these?

People seem obsessed with putting things on their screen; the latest fad is blue light filters, in the past there where grey filters yellow filters and even mesh filters. I think they are all useless. The problem is that people spend too much time looking (staring) at the screen and need to give their eyes a break. That is what the current guidance says and that is what I intend to follow. As you said if one person has one they spread like a rash.

Try f:lux on google. Doesn't need admin rights and can be tailored to individual's preferencese. For me makes late night working more comfortable.

If you are lucky enough to have an enlightened IT department the function provided by f.lux is already built in to Windows 10 Or you could turn down the brightness to suit the user

Thanks to everyone who has replied so far.
I have encourage the person to lower the brightness and the blue from their screen. Along with following good DSE practice (more frequent breaks, looking away, remembering to blink etc).
I think its best for him to try this first and then we can see if anything further needs to be done.
Thank you
