CommentsYes, it is worth getting your eyes checked if your vision remains the same but your eyes get tired easily. While it could simply be fatigue caused by overuse, there may also be underlying causes that are not easily visible on an eye chart, such as dry eyes, reduced focusing ability, or early signs of presbyopia.
In particular, if you experience slow focus, eye strain, or even headaches after looking at close text for a long time, it is advisable to have it checked by an ophthalmologist. For those in their 40s or older, these symptoms may appear first as presbyopia begins to set in.
If it were me, I would start by checking not only your vision but also your refraction test, tear film, and dry eye status. It is best to seek medical attention as soon as possible if the condition has suddenly worsened, if only one eye feels particularly uncomfortable, or if it is accompanied by symptoms such as blurred vision, double vision, pain, or flashes of light.
