Huononäköisyys

Huononäköisyys, sometimes referred to as low vision, is a visual impairment that cannot be fully corrected with eyeglasses, contact lenses, or surgery. It is a condition where a person's eyesight is so poor that it interferes with their daily activities, even with standard corrective measures. This can manifest in various ways, including reduced visual acuity, loss of peripheral vision, difficulty seeing in dim light, or increased sensitivity to glare.

The causes of huononäköisyys are diverse and can include age-related macular degeneration, glaucoma, diabetic retinopathy, cataracts, and various genetic eye conditions. It is not a disease in itself but rather a consequence of underlying eye diseases or injuries. The severity can range from mild impairment to profound visual loss, impacting a person's ability to read, drive, recognize faces, and perform many other essential tasks.

While huononäköisyys cannot be cured, various strategies and aids can help individuals manage their condition and maintain a degree of independence. These include the use of magnifying devices, assistive technology such as screen readers, specialized lighting, and adaptations to the environment. Rehabilitation programs and support services are also crucial in helping individuals with huononäköisyys to cope with their visual challenges and optimize their remaining vision. Regular eye examinations are important for early detection and management of conditions that can lead to huononäköisyys.
