An important eye symptom to be aware of is eye floaters. These floaters have no specific shape, sometimes showing up as cobwebs, strings, or specks. As people age, these floaters have greater odds of showing up and they are associated with changes happening within the eye's gel-like substance called the vitreous, or vitreous humor. Generally, floaters pose no harm to patients but it is strongly advised to visit an eye doctor, particularly if the floaters seem to persist. Acute floaters may indicate a serious issue in the eye requiring treatment such as a retinal detachment or retinal break.
