Blurred vision (धुंधली दृष्टि) is an ocular symptom where vision becomes less precise, and there is added difficulty in resolving fine details. Temporary blurred vision may involve dry eyes, eye infections, alcohol poisoning, hypoglycemia, or low blood pressure. Other medical conditions may include refractive errors such as myopia, high hypermetropia, and astigmatism, amblyopia, presbyopia, pseudomyopia, diabetes, cataract, pernicious anemia, vitamin B12 deficiency, thiamine deficiency, glaucoma, retinopathy, hypervitaminosis A, migraine, sjögren’s syndrome, floater, macular degeneration, and can be a sign of stroke or brain tumor.
Blurred Vision Definition
Blurred vision is a condition in which eyesight becomes unclear or out of focus, making objects appear hazy, fuzzy, or less sharp than normal. It can affect one or both eyes and may occur suddenly or develop gradually over time. In simple terms, blurred vision refers to difficulty seeing fine details clearly, whether at near or far distances, or both. It can be temporary or persistent and may result from problems with the eyes, nerves, brain, or overall health.

Blurred Vision Diagnosis
Blurred vision is diagnosed through a combination of medical history, eye examinations, and diagnostic tests, depending on the suspected cause. The goal is to find whether the problem comes from the eyes, nerves, brain, or an underlying medical condition.
Medical History
The doctor may ask about:
-
When the blurred vision started (sudden or gradual)
-
Whether it affects one or both eyes
-
Duration and frequency
-
Associated symptoms (eye pain, headache, dizziness, double vision)
-
Existing medical conditions (diabetes, hypertension)
-
Medication use
-
History of eye injury or surgery
Eye Examination Tests
-
Visual acuity test – checks the clarity of vision using an eye chart
-
Refraction test – identifies refractive errors needing glasses or contact lenses
-
Slit-lamp examination – examines the cornea, lens, and front of the eye
-
Pupil response test – evaluates nerve function
-
Intraocular pressure test – screens for glaucoma
-
Dilated eye exam – examines retina, optic nerve, and blood vessels
Neurological Evaluation (if needed)
-
Visual field test – checks peripheral vision loss
-
Fundoscopy – examines the optic disc and retina
-
CT scan or MRI – used if stroke, tumor, or nerve damage is suspected
Blood and Medical Tests
-
Blood sugar tests (diabetes)
-
Blood pressure measurement
-
Complete blood count (CBC) – checks for anemia or infection
-
Vitamin level tests (Vitamin A, B12)
-
Thyroid function tests
Emergency Evaluation
Immediate diagnosis is required if blurred vision:
-
Is sudden
-
Occurs in one eye
-
Is accompanied by eye pain, weakness, confusion, or speech difficulty
In such cases, urgent tests may be done to rule out stroke, retinal detachment, or acute glaucoma.
