Blurred vision is a common symptom characterized by a loss of sharpness or clarity in vision, making it difficult to see fine details clearly. It can occur in one or both eyes and may be constant or intermittent. The causes of blurred vision are diverse and can include refractive errors such as nearsightedness, farsightedness, or astigmatism, where the eye's shape prevents light from focusing correctly on the retina. Other common causes include cataracts, a condition where the lens of the eye becomes cloudy, or glaucoma, which can damage the optic nerve and affect vision. Blurred vision can also result from macular degeneration, where the central part of the retina deteriorates, or diabetic retinopathy, a complication of diabetes affecting the blood vessels in the retina. Additionally, blurred vision may be caused by eye infections, dryness, or inflammation. Systemic conditions such as high blood pressure or stroke can also lead to blurred vision.
Treatment for blurred vision depends on its underlying cause. Refractive errors are typically corrected with prescription glasses or contact lenses. Cataracts may require surgical intervention to replace the cloudy lens with a clear artificial lens. Glaucoma and macular degeneration often require specialized treatments such as medication, laser therapy, or surgery to manage and prevent progression. Addressing underlying health conditions, such as controlling diabetes or hypertension, can also help improve vision. For infections or dryness, appropriate eye drops or medications may be prescribed. A comprehensive eye examination by a healthcare provider is essential to diagnose the cause of blurred vision accurately and determine the appropriate treatment to restore visual clarity and overall eye health.
