Nägemistundlikkus

Nägemistundlikkus, also known as photophobia, is a medical term that describes an abnormal intolerance to light. This condition can cause a person to experience discomfort or pain when exposed to ordinary levels of light. It is not a disease itself, but rather a symptom of an underlying medical condition.

The severity of photophobia can vary greatly among individuals. Some may experience only mild discomfort, while others can find even dim light unbearable. The light sensitivity can affect one or both eyes and may be accompanied by other symptoms such as headaches, eye strain, or tearing.

Numerous conditions can lead to nägemistundlikkus. Common causes include eye infections like conjunctivitis or keratitis, inflammation of the iris (iritis), and certain neurological disorders such as migraines and meningitis. Dry eye syndrome, corneal abrasions, and even certain medications can also trigger light sensitivity. In some cases, prolonged exposure to screens or artificial light can also contribute to temporary photophobia.

Diagnosis of nägemistundlikkus typically involves a comprehensive eye examination by an ophthalmologist or optometrist. The doctor will assess the patient's medical history, perform visual acuity tests, and examine the eyes for any signs of disease or injury. Identifying the underlying cause is crucial for effective treatment.

Treatment for nägemistundlikkus focuses on addressing the root cause. This might involve antibiotics or antiviral medications for infections, anti-inflammatory drugs for iritis, or specific therapies for neurological conditions. For temporary or mild cases, simply reducing light exposure by wearing sunglasses or dimming lights can provide relief. In severe cases, tinted lenses or specialized eyewear may be recommended.
