Blurred vision or decreased vision is a visual disturbance where objects appear fuzzy, unclear, or less sharp than normal. This symptom can arise from various common causes and related conditions
Common Causes of Blurred Vision or Decreased Vision
Refractive Errors: The most common cause, conditions like myopia (nearsightedness), hyperopia (farsightedness), or astigmatism can result in blurred vision when the eye’s focusing ability is compromised.
Presbyopia: Age-related loss of near vision due to reduced flexibility of the eye’s lens.
Cataracts: Clouding of the eye’s natural lens, often related to aging but can also occur due to injury or disease.
Glaucoma: Increased intraocular pressure can damage the optic nerve, leading to decreased peripheral vision.
Macular Degeneration: Age-related macular degeneration (AMD) can cause central vision loss.
Diabetic Retinopathy: A complication of diabetes that damages the blood vessels in the retina, resulting in vision problems.
Dry Eye Syndrome: Insufficient tear production can lead to dry, irritated eyes and blurred vision.
Eye Infections: Infections like conjunctivitis or keratitis can cause eye redness and blurred vision.
Medications: Some drugs, such as anticholinergics, antihistamines, or corticosteroids, can affect vision as a side effect.
Neurological Disorders: Conditions like multiple sclerosis or stroke can impact visual pathways, causing blurred or double vision.
Migraines: Some migraine sufferers experience visual disturbances, known as aura, including temporary blurred vision.
Proper evaluation of blurred or decreased vision involves a comprehensive eye examination, including visual acuity tests, tonometry (pressure measurement), dilated eye exams, and sometimes imaging studies. Clemenceau Medical Center Hospital offers specialized eye care to diagnose and manage the underlying cause of vision problems, ensuring optimal visual health and treatment.
