Low vision refers to a visual impairment that cannot be fully corrected by glasses, contact lenses, medication, or surgery, and significantly impacts a person's ability to perform daily activities. Unlike total blindness, individuals with low vision still retain some degree of sight, but it is often blurred, limited, or distorted. This condition can result from various eye diseases, congenital conditions, or injuries.
People with low vision experience difficulties with tasks such as reading, writing, driving, recognizing faces, and navigating their surroundings. They may require assistance and adaptive aids to compensate for their reduced vision, such as magnifiers, large-print materials, or screen-reading software.
The causes of low vision are diverse and can include age-related macular degeneration, diabetic retinopathy, glaucoma, cataracts, retinitis pigmentosa, and congenital disorders like albinism or optic nerve hypoplasia. Each condition manifests differently and affects visual acuity, contrast sensitivity, peripheral vision, or color perception to varying degrees.
Living with low vision can have significant impacts on an individual's independence, emotional well-being, and quality of life. It may necessitate adjustments in lifestyle, employment, and recreational activities to accommodate visual limitations. Rehabilitation services, including vision therapy, orientation and mobility training, and counseling, can help individuals with low vision maximize their remaining sight and regain confidence in performing daily tasks.
Support from family, friends, and healthcare professionals is crucial in helping individuals with low vision adapt to their condition and maintain an active and fulfilling life. Through a combination of adaptive strategies, assistive technologies, and community resources, people with low vision can overcome challenges and participate fully in society.
