Glossy screens might be useful for color rendering, but for normal work related tasks they are horrible. So I needed a non glare screen “protector” for my surface.
I ended up buying a tech armor anti glare screen protector:

Good fit. Takes away all the glare and makes the surface very useful in normal office environments.
Is the sharpness slightly reduced: yes. Do I care: NO. It is that much more pleasant on the eyes not having the glare!
