I've spent the whole day glued to the computer screen
What made you stay glued to the computer screen?
It was my day off and I played lots of games.
The glare from a computer screen can harm you. It's unhealthy to spend all day on the computer. You should take breaks and walk outside from time to time.
Eh, I'm fine. I usually turn on f.lux to reduce eye strain. Its a very helpful addition to my computer system and to myself.
Well, it s great you found something to help you out with the eye strain. Who would have guessed there exists such a thing. Evenstill, taking a break now and then is good for your body.
