My eyesight is fine, but what kind of tests should I get because of eye strain?

Lately, after looking at the computer for a long time, instead of my eyes feeling dry, I sometimes feel like my focus isn't quite right.

It feels better after a short rest, so I thought it was just due to fatigue 👀 but I'm wondering if I need an examination to distinguish between simple eye strain and issues with my vision or focusing function.

Just because the numbers appear clearly on the vision chart, can we assume that all other eye functions are normal?

And what kind of tests would be good to get in this case?

컴퓨터를 오래 본 뒤 초점이 잘 안 맞는다면 단순 피로 외에도 굴절 이상, 조절 기능 문제, 양안시 문제 등이 관련될 수 있어요. 이런 증상이 있다면 안과에서 종합적인 눈 검진을 받아보는 게 좋아요 검사 전까지는 20분마다 약 20초 정도 먼 곳을 바라보는 20-20-20 습관, 화면을 눈에서 팔 한 뼘 정도 떨어뜨리고 약간 아래에 두는 것도 도움이 될 수 있어요
