Patients with retinal detachment may experience flashes of light in front of their eyes due to irritation of the retinal cells, even during the day. The flashes of light in retinal detachment patients are mostly caused by mechanical pulling or exudation and other factors that stimulate the retinal cells, so they can occur both during the day and at night. At the same time, in addition to the flash sensation, patients with retinal detachment may also have uncomfortable symptoms such as dark shadows in front of their eyes, distorted vision, and decreased vision. If a patient has frequent flashes of light, there is a possibility of retinal detachment, it is recommended that the patient consult a hospital in time to assess the condition and follow the doctor’s instructions for treatment to avoid delaying the condition.
