Also known as: Visual Acuity Impairment
Blurred vision refers to a loss of sharpness in eyesight, making objects appear out of focus. It can affect one or both eyes and may develop gradually or suddenly.
Blurred vision is one of the most common visual complaints. The most common cause is uncorrected refractive error, affecting approximately 2.7 billion people globally.
Gradual blurring typically points to refractive changes or cataracts. Sudden blurring, especially in one eye, may indicate retinal detachment, optic neuritis, or stroke.
Digital eye strain has become increasingly prevalent, causing temporary blurring that resolves with rest and breaks.
There are several possible reasons you may be experiencing Blurred Vision. Here are the most common ones.
Myopia, hyperopia, and astigmatism cause light to focus improperly on the retina, easily corrected with glasses or contacts.
Prolonged screen use reduces blink rate and causes fatigue, leading to temporary blurred vision.
Clouding of the eye's lens causes progressive blurring, primarily affecting people over 60.
High blood sugar damages retinal blood vessels, causing leakage and swelling.
These approaches may help manage blurred vision at home. Always consult a healthcare provider if symptoms persist or worsen.
Every 20 minutes, look at something 20 feet away for 20 seconds.
Lubricating drops relieve dryness-related blurring.
Adequate lighting reduces strain when reading or working.
Comprehensive eye exam including visual acuity testing, refraction, slit-lamp examination, and retinal evaluation.
Seek immediate care if blurred vision occurs suddenly, is accompanied by severe headache, difficulty speaking, weakness on one side, or eye pain. Sudden vision loss is a medical emergency.
Steps you can take to reduce the likelihood of experiencing blurred vision.
Regular eye exams every 1-2 years
Frequent screen breaks
Manage blood sugar if diabetic
UV-protective sunglasses
Temporary blurring from strain often resolves with rest. Persistent blurring needs professional evaluation.
Yes, high glucose causes fluid shifts in the lens, altering focus.
Sudden onset with headache, weakness, or visual shadows requires immediate emergency care.
