7 Questions to Test for Light Sensitivity
How do I know if I am light sensitive or if I have photophobia? Whether due to migraine, post-concussion syndrome or something else entirely, this is a question that millions of patients ask themselves and their doctors at some point—and unfortunately the answer is not always easy to come by. However, it is not impossible either. Based on reliable models that have been used in clinics, these are some of the key questions that can test if you have light sensitivity.
How Did We Develop the Light Sensitivity Test and Questionnaire?
It has long been a challenge to research and test an individual’s light sensitivity; to understand the physiological reactions of light can mean risking pain and other symptoms through direct exposure while questionnaires often rely on the incomplete and sometimes inaccurate recall of patient memory. But researchers and medical professionals have undertaken numerous efforts to create reliable instruments that measure photophobia and light sensitivity. Notably, the Photophobia Questionnaire for Headache Patients (Choi, et al.),[1] the Photosensitivity Assessment Questionnaire,[1] and the Visual Light Sensitivity Questionnaire (Verriotto, et al.)[2] served as guiding examples of the types of diagnostic probing necessary to understand the extent to which a person is light sensitive. We also expanded on these questions based on our own insight and experiences with thousands of light-sensitive individuals.
We also want to remind you that this should not be used for official diagnosis and is not a substitute for the opinions of a medical professional.
