Keep all screens clean and avoid working while
there is glare on the screen

Here is a quick check.

Turn off your computer.Do you see any reflections left on the screen?Did you see the window behind you or the bright ceiling light?
If so, your computer is causing glare.Turn the screen away from those reflections.
Remember to take eye-rest breaks even when set up optimally.
Use the 20-20-20 Rule.
Every 20 minutes,
look at something 20 feet away
for 20 seconds.

There is a little video that shows you how to do it and the picture above shows you the points you will need to press with your fingers:
