It is not unusual for a person with convergence insufficiency to cover or close one eye while reading to relieve the blurring or double vision. Symptoms will be worsened by illness, lack of sleep, anxiety, and/or prolonged close work.
Thanks! My left eye has been weaker my whole life. Now I also have diplopia from my stroke, so I wear prism lenses. I've also done visual training rehab (similar to eye push-ups) which was part of Vestibular Rehabilitation Therapy. Despite all this, my left eye still wants to close out of life-long habit.
