P2425H, eye strain

I have a P2425H Monitor and I am having issues with Eye discomfort from looking at it all day.  I have seen other posts for other monitors that users are reporting the same thing.  I am not finding the eRGB under the color settings on the Monitor.  I have tried the other "Preset Modes" with no luck.  Can not use a Privacy screen because I have to also look at it from afar sometimes.  Wondering if anyone has any other suggestions for this issue.
