Blue light filter

[KEM.UK]

Is it best to get a monitor with low blue light or buy a special blue light filter?

There's no need to buy anything. You can just use software to change the colour of your screen and remove the blue light in the evening (when this is important). There's nothing wrong with blue light during the day.

If you're using a Mac, you can just enable Night Shift in your system settings. If you don't have that, another good option is f.lux (https://justgetflux.com/).
