If night blindness is caused by congenital reasons, then staying up late generally does not significantly worsen it. If it is caused by acquired eye abnormalities, staying up late will noticeably exacerbate the occurrence of night blindness. Additionally, if it is caused by a deficiency in vitamin A, one should rest properly, reduce close-range activities, avoid staying up late, and supplement with foods or medications containing vitamin A. If the night blindness is due to eye-related causes, active treatment and regular follow-ups are recommended. If it is due to congenital reasons, currently there are no particularly effective treatments available.
