bländningstest

A bländningstest, or glare test, is a vision examination designed to assess a person's tolerance to bright light or glare. This test is crucial for diagnosing conditions that can cause light sensitivity, also known as photophobia. During a bländningstest, a controlled light source is directed towards the patient's eyes, and their reaction is observed. This can involve noting how long they can comfortably keep their eyes open, or how much visual discomfort or reduction in vision they experience.

Different types of bländningstests exist, ranging from simple subjective assessments where the patient describes their discomfort level, to more objective measures that quantify visual performance under glare conditions. The intensity and duration of the light exposure can be varied to simulate different real-world scenarios. For instance, tests might mimic the glare from headlights at night or the brightness of sunlight.

Conditions that might be identified or evaluated using a bländningstest include cataracts, corneal abrasions, certain inflammatory eye diseases like uveitis, and even neurological conditions affecting light perception. The results of a bländningstest help ophthalmologists and optometrists determine the severity of light sensitivity and guide treatment strategies to improve a patient's visual comfort and function in bright lighting. It is a common part of a comprehensive eye examination, especially for individuals reporting symptoms of glare.
