Doing my homework

I was writing two stories for my English class.

I feel bad because I have been staring at the display on my PC.

It is like a motion sickness. The only way to get over is to take a rest.

So, I stop my homework and taking a bath right now.

How do I write this blog while I take a bath? I do it with my smartphone.

Different from PC, I don’t feel bad if I gaze at the display on my SP.

I guess this smartphone cuts a lot of blue lights from the display. Therefore, it’s safe to my eyes.

This is why, I prefer SP to PC recently. I cannot help wondering at the progress of science. It’s just my own opinion.
