Etymology

The term "blurred" comes from the Middle English word "bluren", which means to smear or blur. The term "vision" comes from the Latin word "visio", which means sight.

Definition

Blurred vision can occur when one or both eyes fail to focus light correctly. It is often associated with conditions affecting the eye or the visual system. It can be a symptom of numerous health conditions, ranging from minor issues to more serious health concerns.

Causes

Blurred vision can be caused by a variety of factors, including refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism, and presbyopia (age-related farsightedness). Other causes can include cataracts, glaucoma, macular degeneration, diabetic retinopathy, and migraines.
