Myth: Bipolar disorder always involves mania.įact: While bipolar I disorder involves episodes of mania, bipolar II disorder and cyclothymic disorder involve hypomania instead. Just as beliefs about bipolar disorder’s impacts on the eyes are often based in myth rather than fact, some other common myths about bipolar disorder still persist. It’s possible that these medications were partly responsible for some changes in eye movement rather than bipolar disorder itself, though more research is needed to confirm this. It’s important to note that in many of these studies, people who participated were using medications to manage their condition. People with bipolar disorder also experienced more saccadic movements that interrupted the vergence movements. It found that bipolar disorder was linked to more errors in carrying out the vergence movements needed to focus on a specific object. Meanwhile, a 2019 study suggests that bipolar disorder could impact vergence eye movements. The same research also found that depressive episodes made people with bipolar disorder more likely to focus on threatening images and to have trouble keeping eye contact with positive images. Vergence movements help you focus on objects at different distances from you.Ī 2015 study that measured saccadic eye movements in people with bipolar disorder found slower reaction times in their eye movements during depressive episodes. Vergence movements: Movements that allow you to perceive depth by causing your eyes to move in opposite directions.Saccadic movements: Side-to-side movements that occur when you’re reading, during the rapid eye movement (REM) phase of sleep, or when you’re looking around your environment.Squinting and narrowing eyes is also a response to too much brightness, so if your pupils are dilated due to a high or low mood, you might be slightly more prone to squinting, causing the eyes to appear narrower.Įxcitement - another strong emotion associated with mania - might cause your eyes to look wider or more energetic than usual.Īnd though a mood episode can’t really change your eye color, enlarged pupils and confirmation bias could help explain why this idea exists.įor example, if your eyes are naturally two-toned with a ring of one color nested inside that of another color, dilated pupils may cover up part of your eye color, making it look like your overall eye color has changed.īipolar disorder could impact a couple types of eye movement: In addition, dilated pupils could make you more sensitive to light.Ī 2019 study suggests that people with bipolar disorder might be more sensitive to light when experiencing a mood episode like hypomania. Manic episodes sometimes cause psychosis, including hallucinations and delusions, which could also make the pupils larger. ![]() A 2015 study suggests that pupils tend to dilate, or grow larger, during times of high emotional arousal, such as during an unusually high or low mood. If you’re trying to figure out whether a loved one is experiencing bipolar disorder, reviewing a complete list of symptoms is a much more reliable method.įor instance, pupil dilation is often responsible for eyes that look dark or black.
