According to your present age, it is unlikely that you will suffer from pseudomyopia. According to the description, the condition of your eyes can only be the symptoms of visual fatigue caused by excessive use of eyes, but it does not rule out the problem of mild myopia.

Suggestion:

These are just clinical manifestations, which may be caused by many reasons. In order to ensure the diagnosis, it is recommended that you go to the ophthalmology department of a professional hospital for further detailed examination and timely symptomatic treatment. If the problem is caused by myopia, you should consider wearing glasses to correct your vision. If the degree is low, you can wear it at a distance.
