It is normal that eyes feel burning in a short time when you walk out from a dim place to a bright place or the sun is too bright in the noon. But if you fear the sunlight in the normal situation and have the symptoms of narrowing your eyes or bursting into tears, such case should arouse your alert. In most cases, having a cold or sinus infection can stimulate the ocular nerve and cause the pain in the eye, resulting in eye burning in the sunlight. If you have been troubled by the fear of light for a long time, you should go to see a doctor as early as possible. You know, if the slight sensitivity to sunlight is a sign of glaucoma, the more early you receive a treatment, the more likely you are cured. If your eyes are sensitive to the light just like some skins are sensitive to the light, you could select a pair of suitable sunglasses.
