What could be the cause of my double vision

Did you perform any surgery for the eyes?
Do you suffer from pre-existing illnesses in the eye?


Do you suffer from any diseases in the body?

Pre-diabetes, but nothing wrong with my retina and my blood sugar is well controlled. No medication needed.

Do you use any eye drops?
Do you wear Contact lenses or Eyeglasses?

I wear glasses and tried contacts. The contacts even for astigmatism did not work for me. I have 40/20 vision in both eyes.





December 28, 2018, I had sudden double vision issues. It was double vision that was vertical. I went to the ER. They did a CT and said there were no abnormalities. The next day I saw an optometrist. He said my left eye was over compensating for my right eye.

My left eye is the one with double vision and an astigmatism. He prescribed contact and glasses. I have been using them for over a week. The double vision was back with the contacts, he tried contacts for astigmatism today. They didn’t help.

So I’m using glasses and the double vision has returned. It is for distance objects, especially traffic lights (green and red only) and tail lights. When I cover my right eye, and try to read with my left one, I get vertical double vision (this is all with glasses on).



Please help! I don’t know what to do. Should I see an ophthalmologist and my insurance plan? Or is it just from the astigmatism? But please keep in mind that I haven’t had double vision before this. I’ve had an astigmatism diagnosed since I was a teenager. My vision in both eyes is 40/20.




Thanks for your Question



The most important thing in double vision is to find if the double vision monocular or binocular. Binocular double vision occurs when your both eyes are open but will disappear when you cover one eye. This kind of double vision should be investigated with extra-ocular muscles examination and brain imaging.

Monocular double vision occurs when both eyes are open and also when you cover one of your eyes. This type of double vision are due to problems within the eye itself not from eye motility or brain.

There are many causes of monocular double vision such as astigmatism, keratoconus, cataract or retinal diseases. You should visit an ophthalmologist in order to run the full eye examination to find the cause of this sudden double vision.
