I'm not sure you are asking the right question. If you goal is to reduce eye strain which can lead to terrible headaches simply getting a monitor is not the total solution. I went through a few doctors and even an MRI only to discover accidentally that my new vision prescription and new phone/computer habits fixed it right up. You are getting older every day. This is what works for me, try it and see if it helps:

1) keep ALL screens at arms length from your face 2) code at night with a lamp on 3) 2x 27 inch displays (new toys!) 4) Look off into space here and there

I tried f.lux but I don't think it did anything for my sleep or eyes.
