Blurry vision is a symptom where vision lacks clarity, causing objects to appear fuzzy, hazy, or out of focus. This symptom can affect one or both eyes and may develop gradually or occur suddenly, depending on the underlying cause.
Causes: Blurry vision can result from refractive errors like myopia
(nearsightedness), hyperopia (farsightedness), astigmatism, or presbyopia. It
may also be a symptom of eye conditions such as cataracts, glaucoma, or
macular degeneration. Systemic conditions like diabetes, which can cause
diabetic retinopathy, or neurological issues such as strokes, can also lead to
blurry vision. Other causes include dry eye syndrome, eye infections, and
prolonged digital screen use (computer vision syndrome).
Symptoms: Besides blurriness, individuals may experience headaches, eye
strain, double vision, or sensitivity to light. If the condition is due to an eye
disease, additional symptoms such as halos around lights, floaters, or loss of
peripheral vision may be present.
Treatment: The treatment of blurry vision depends on its cause. Refractive
errors can be corrected with glasses or contact lenses, while surgical procedures
like LASIK or cataract surgery may be required for certain conditions. Eye drops
or medications are commonly used for dry eyes or infections. For systemic
causes, managing the underlying health condition is crucial in restoring vision.
