People experiencing double vision, or diplopia, may notice a hazy ghost image surrounding the objects in their line of sight, or they may even notice two entirely separate images.
In addition, double vision can be horizontal or vertical. Anyone who has experienced prolonged double vision can tell you, it makes it hard to go about your day.
It is always a good idea to pay close attention anytime you experience diplopia because it can be a sign of a serious medical issue. You may even want to write down how long the episode lasted, how the images were doubled, and whether it was present with one eye closed. You can have double vision in just one eye!
If your double vision is only present in one eye, it is called “monocular.” There are several reasons why you may only be seeing double in a single eye. You might have astigmatism in that eye or a cataract that is distorting your vision. If it seems to improve when you blink, you could have a dry or irritated cornea.
Double vision can mean that you need medical attention. Prolonged diplopia can be a sign that something is seriously wrong – you may be suffering from a head injury or have had a stroke. However, double vision isn’t always a sign of something serious.
There are treatable eye conditions such as dry eye that can be the cause of your doubling. Plus, issues like cataracts, refractive errors, and eye muscle weakness can also be to blame. Temporary double vision can even be caused by having one-too-many drinks at dinner or staying up too late.
Whether your double vision is in one or both eyes, if it lasts for more than a couple of hours, it is something you want to discuss with your eye care professional right away.
