It seems to be early presbyopia.

Recently, I went to the ophthalmology clinic for my youngest child's vision test, and I also experienced some eye discomfort, so I had a check-up myself. Usually, my work involves constantly focusing on a monitor. Continuously staring at the monitor makes my eyes feel slightly stinging when I blink, and my eyes become very dry and fatigued, almost as if they are drying out and my eyes are very tired. So I visited an ophthalmologist, and the doctor said... I have now reached an age where presbyopia is a concern. He casually mentioned that I should be more conscious of blinking frequently for eye health, and he prescribed artificial tears. Ah~~ I can't believe my age already... Gasp, is there a way to slow down or prevent presbyopia from progressing?
