FIT5 How-tos for Kids :: How to correct your eyesight and do eye muscle exercises :: Eyesight :: Do vision disturbances correlate with other disorders?

Yes.
Incorrect posture can cause deterioration of vision. Neck muscle cramps cause tension that affects our eyes. Hanging our heads causes the position of the eyes to change.
