Patient's Query

Hi doctor,

I experienced double vision in a 100-mile trail run around 18 hours into the race. The double vision cleared after 20 minutes of closing my eyes in the medical tent. After a week, I saw an ophthalmologist who did a few tests and concluded that it was eye fatigue. I experienced double vision in a triathlon just after the swimming portion (30 minutes into the race). What is the reason for having double vision and is it preventable? Is there any reason other than fatigue that causes double vision? It never happened in my regular day to day activities.


Welcome to icliniq.com.

It seems that you have phoria (not strabismus) and the fatigue in eye muscle cause double vision. I advise you to decrease the effort. Take good time to rest and use vitamin B (1,6,12) and keep your vision good (always about 20/20) by glasses or without any problem in your vision.

Same symptoms don't mean you have the same problem. Consult a doctor now!
