Double vision is when you see two images of one object. It can be the sign of a serious condition or simply the result of too much screen time or having the wrong prescription in your glasses. Double vision can affect one or both eyes, depending on the cause. Double vision in one eye is referred to as monocular, in both eyes it is called binocular.
You should always see a doctor about double vision. Even if it comes and goes it can be a symptom of a serious condition. If you have double vision and eye pain, or double vision and a severe headache, seek medical help immediately.

- brain tumour
- Graves’ disease
