It appears that your two eyes are having difficulty working together, causing your double vision. This misalignment of the eyes are usually due to a disruption of the nerves going to the eye muscles.

Your description of the objects one on top of the other is termed vertical diplopia. The most common cause of this is due a weakness of the 4th cranial nerve. This can be damaged by trauma, such as falling and hitting your head. It is also non uncommon for people to be born with a weakness of the 4th cranial nerve. They don't have double vision because they are able to compensate for it. It can come out in times of tiredness.

Depending on your prescription, the double vision can be due to an inappropriate prescrition. If you are using your distance prescription for reading, that can cause double vision along with images being out of focus. Bifocals can help with that.

Vertical diplopia can occasionally be due to problems with the brain. These tend to be accompanied by other symptoms. I recommend you visit with your ophthalmologist for a complete exam to determine the cause of your double vision.
