My eyes are blurry.

I'm in my mid-50s, and my eyes have been very blurry lately.

When I look at the computer, my eyes get very tired, and I often have tears in my eyes when I wake up in the morning. I also can't look at my smartphone for a long time. I thought my glasses prescription might be wrong, but when I checked, they said there was no problem.

I'm just curious if it's because of presbyopia.
