Sudden double vision

[Eriu22]

Hey all. The other day I noticed sudden vertical double vision in one of my eyes. From the most part, its just ghosting on bright objects, but there are times when I can see a clear, shadowy version or something right above what I'm looking at. This has mostly been text on a screen.

Now I should mention in my other eye I have amblyopia with super high errors which I get double and some times triple vision from. That is something I've always had to deal with. For some reason, my doctor never gave me a corrective lens for this.

But anyway, when I cover my bad eye I still see the double vision. And it does seem to get better when getting closer to the object, and through a pin hole. Any idea what could be causing this?

The sudden onset is the most concerning thing and you need to get in to see an Eye MD ophthalmologist for an evaluation to include macular OCT.  Sudden onset of unilateral ghosting may be due to macular disease.  Problems related to cataract formation or cornea disease tend not to come on suddenly.  If you wear contact lens they can also cause this problem as a result of fitting problems.
