Most doctors consider floaters a natural part of the aging process and a normal variation of vision in some people. However, the condition doesn’t usually cause floaters or eye flashes.ĭoctors separate the symptoms of eye flashes and eye floaters. One study in 2015 did find that people who reported anxiety, depression, and stress were more likely to have dry eye disease than those who didn’t. There aren’t many other studies that suggest that stress can lead to problems with vision. This is called a migraine aura.Įye flashes from a migraine aura may appear like jagged lines or cause a person’s vision to appear wavy.Īs stress can be a trigger for some migraine attacks, it’s possible there’s a connection between stress, migraine, and eye flashes. Migraine attacks can cause visual disturbances and changes that lead to flashes of light. The results of this study bring up a “chicken or egg” debate where researchers contemplate if flashes or floaters create anxiety or vice-versa. They then asked about a person’s psychological response to the flashes and floaters, including questions about depression and anxiety.Īt the study’s conclusion, the group who had eye flashes reported greater incidence of depression, anxiety, and perceived stress levels compared to the group that didn’t see floaters or flashes. The surveyors asked questions about how frequently the participant’s experienced eye floaters, how severe their symptoms were, and if the person saw eye flashes. They then compared the results to 34 control subjects without eye floaters. In one study in 2017, researchers surveyed 61 people who saw vitreous floaters (small specks in their vision) that weren’t due to a severe or concerning underlying eye disorder. Unfortunately, it’s not very well researched. The concept that anxiety or other strong emotions could cause changes in what a person sees isn’t a new concept.
