Causes of Foggy VisionThere are numerous potential causes of foggy vision, including refractive errors, cataracts, glaucoma, age-related macular degeneration (AMD), dry eyes, corneal diseases, and even certain medications.
- Refractive errors, such as myopia (nearsightedness), hyperopia (farsightedness), presbyopia (age related farsightedness), and astigmatism, are the most common causes, affecting approximately 60% of the global population. Learn more about nearsightedness and farsightedness here (/ocular-disease/understanding-nearsightedness-and-farsightedness-causes-symptoms-and-diagnosis/).
- Cataracts, a clouding of the lens, is another leading cause, impacting nearly 24.4 million Americans aged 40 and above. Learn more about cataracts here (/ocular-disease/cataracts/).
- Glaucoma, a group of eye conditions characterized by damage to the optic nerve, can also result in foggy vision, with over 3 million Americans affected. AMD, which affects the central part of the retina, is a leading cause of vision loss in people aged 50 and older, with around 11 million cases in the United States alone. Learn more about AMD here (/low-vision/age-related-macular-degeneration-and-low-vision/).
- Dry eye syndrome, corneal diseases, and certain medications can also contribute to this condition, underlining the importance of proper eye care and regular check-ups. Learn more about dry eye syndrome here (/dry-eye/dry-eye-parent/).
- Diabetic retinopathy can lead to damaged blood vessels in the retina. It is essential to manage your diabetes and follow our eye doctors recommendation to prevent permanent vision loss.
- Migraine: A severe headache that can cause visual disturbances, including blurry vision.
- Ocular migraine: A type of migraine that specifically affects vision, causing temporary vision loss or visual disturbances.
- Floaters: Tiny specks or "cobwebs" that float across the visual field, potentially causing blurred vision.
- Corneal abrasion: A scratch on the cornea that can cause pain, redness, and blurred vision.
- Corneal infection: An infection of the cornea, often caused by bacteria, viruses, or fungi, leading to vision problems.
- Uveitis: Inflammation of the uvea, the middle layer of the eye, causing pain and vision issues.
- Sjögren's syndrome: An autoimmune disorder that causes dry eyes and mouth, leading to blurry vision.
- Conjunctivitis (pink eye): Inflammation or infection of the conjunctiva, causing redness, discharge, and blurred vision.
- Keratoconus: A progressive eye condition in which the cornea thins and bulges into a cone-like shape, causing blurred vision.
- Optic neuritis: Inflammation of the optic nerve, often linked to multiple sclerosis, causing vision loss.
- Lens dislocation or subluxation: A displacement of the eye's lens, leading to vision problems.
