näköhaittoja

Näköhaittoja refers to visual impairments or vision problems. These can range from minor difficulties in seeing clearly to severe or total blindness. Common causes of näköhaittoja include refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, which can often be corrected with glasses or contact lenses. Other causes can be more serious and may involve diseases affecting different parts of the eye, such as the retina, optic nerve, or lens.

Age-related macular degeneration (AMD), glaucoma, cataracts, and diabetic retinopathy are significant contributors to näköhaittoja, particularly in older populations. Infections, injuries, and congenital conditions can also lead to vision loss. Symptoms can vary widely and may include blurred vision, double vision, difficulty seeing in low light, blind spots, or a complete absence of sight.

Diagnosing näköhaittoja typically involves a comprehensive eye examination by an ophthalmologist or optometrist. Early detection and treatment are crucial for managing many vision-threatening conditions and preserving remaining vision. Rehabilitation services and assistive devices are available to help individuals with näköhaittoja maintain independence and quality of life. Prevention strategies, such as regular eye check-ups, protecting eyes from UV radiation, and managing underlying health conditions like diabetes, play a vital role in reducing the incidence and impact of visual impairments.
