Silmävian

Silmävian is a Finnish term that translates to "eye defect" or "vision impairment" in English. It broadly refers to any condition that affects the normal functioning of the eye, leading to reduced vision. This can encompass a wide range of issues, from minor refractive errors to severe visual loss.

Common causes of silmävian include refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, which occur when the eye's shape prevents light from focusing properly on the retina. Age-related conditions like presbyopia, cataracts, and macular degeneration also contribute significantly to vision impairment. Other causes can include glaucoma, diabetic retinopathy, and amblyopia (lazy eye).

Symptoms of silmävian can vary depending on the underlying cause and severity. They may include blurred vision, double vision, difficulty seeing in low light, seeing floaters or flashes, eye pain, or a complete loss of vision. Early detection and diagnosis are crucial for managing many eye conditions and preserving sight.

Diagnosis typically involves a comprehensive eye examination by an ophthalmologist or optometrist. This examination may include visual acuity tests, refraction tests, eye pressure measurements, and examination of the internal structures of the eye. Treatment options depend on the specific diagnosis and can range from corrective lenses (glasses or contact lenses) and medication to surgical interventions. In cases of irreversible vision loss, visual aids and rehabilitation services can help individuals adapt and maintain independence.
