Photophobia is the most obvious eye problems. Eh, generally speaking, photophobia means that people is afraid of light and sensitive to light. While, my elder sister (a doctor) told me that photophobia is a symptom of abnormal intolerance to visual perception of light. But what do really cause photophobia? I did a deep search online and found that several different medical conditions may lead to photophobia , such as the eye or the nervous system, that is , too much light entering eyes, overstimulation of the photoreceptors in the retina, excessive electric impulses to the optic nerve and excessive response in the central nervous system. And there are still some common causes which may develop photophobia, they are migraine headaches, cataracts. The best treatment for light sensitivity is to address the underlying cause. If you really got photophobia, visit a doctor as soon as possible and take a note from him/her and receive a good treatment.
