A condition in which someone does not see objects clearly.
A lack of sharpness when viewing an object, resulting in unclear visual details. Blurred vision can have a number of causes, including farsightedness, nearsightedness, astigmatism (distortion caused by asymmetry in the eyeball), cataract (clouding of the lens of the eye, usually caused by aging), deterioration of the light-sensitive (because of macular degeneration oi diabetic retinopathy, for example), glaucoma (a disease that results in damage to the optic nerve), infection in or injury to the eye, extreme fatigue, exposure to the elements (such as snow blindness], and drugs and medications (such as alcohol and antihistamines). Blurred vision that persists should be evaluated professionally. Treatment depends on cause. Refraction problems such as farsightedness and nearsightedness can be treated with glasses or contact lenses. Surgery may be necessary for cataracts, certain kinds of retina problems, or injury. Glaucoma can be treated with medication, laser surgery, and traditional surgery. If drug is the cause of blurring, abstaining or changing to a different medication may resolve the vision problem; talking to the doctor about a change in medication is the first step.
Blurred vision refers to the presence of unclear or fuzzy visual images. It is important to distinguish blurred vision from double vision (diplopia), as they are distinct conditions. Blurred vision can affect one or both eyes and may occur intermittently for varying durations. It can manifest gradually or suddenly. Prolonged blurred vision is commonly caused by refractive errors such as astigmatism (irregular curvature of the front of the eye), hypermetropia (long-sightedness), or myopia (short-sightedness). These refractive errors can be effectively corrected using glasses or contact lenses. Additionally, after the age of 40, a condition called presbyopia becomes more prevalent, leading to a reduced ability to focus on nearby objects.
Vision can also be blurred or impaired due to damage, diseases, or abnormalities affecting various parts of the eye or its connections to the brain. Blurred vision resulting from such conditions is frequently associated with cataracts or retinopathy. Cataracts involve the clouding of the eye’s natural lens, leading to visual distortion and reduced clarity. Retinopathy, on the other hand, encompasses a group of diseases affecting the retina, potentially causing blurred vision and other visual disturbances. It is important to consult with an eye care professional for a comprehensive evaluation and appropriate management when experiencing persistent or concerning blurred vision, as it can be indicative of underlying eye conditions that require treatment or intervention.
