Looking directly at the sun can cause macular degeneration. The sun is one of the strongest sources of light that we can encounter in our lives, and without any protection, looking directly at the sun on a sunny day can cause macular degeneration by burning the macula due to the bright light, which can be diagnosed by an OCT. In addition, cumulative damage from prolonged bright light increases the risk of macular degeneration. If the macula is damaged, there will be typical symptoms such as dark area in the center of the visual field, vision loss, distorted vision, and twisted vision. Patients must visit the ophthalmology department of the hospital in time, and the doctor will confirm whether macular degeneration has occurred through detailed examination.
