Ljuskänsligheten

Ljuskänsligheten, often referred to as photophobia, is a medical term describing an abnormal intolerance to light. It is not a disease in itself, but rather a symptom of an underlying condition. Individuals experiencing photophobia may find normal light levels uncomfortable or even painful, leading them to squint, close their eyes, or seek dark environments. The severity can range from mild discomfort to extreme light aversion.

Several factors can cause photophobia. Ocular conditions such as dry eye syndrome, uveitis, keratitis, and certain eye injuries are common culprits. Migraines are also frequently associated with photophobia, with light sensitivity being a prominent symptom during an attack. Neurological disorders, including meningitis and concussions, can also manifest with photophobia. Furthermore, certain medications and even prolonged exposure to screens can contribute to this symptom.

Diagnosis of photophobia typically involves a thorough medical history and a comprehensive eye examination to identify any underlying ocular issues. If no eye-related cause is found, further investigation may be necessary to rule out other medical conditions. Treatment for photophobia focuses on addressing the root cause. This may involve managing dry eye, treating inflammation, controlling migraines, or adjusting medications. In the meantime, strategies like wearing sunglasses, using dim lighting, and avoiding bright screens can help alleviate discomfort.
