The appearance of red eyes in pictures, known as the "red-eye effect," occurs when a camera captures light reflecting from the retina at the back of your subject's eye when a flash is used at night and in dim lighting. Therefore, a large burst of light reaches their retinas, reflects back, and is captured on film.
Red eyes can be caused by various factors such as irritation, fatigue, Allergies, or an underlying health condition. The redness is often due to the blood vessels in the eyes becoming dilated or inflamed, resulting in a reddish appearance of the sclera (the white part of the eye). If red eyes persist or are accompanied by pain or vision changes, it is advisable to consult a healthcare professional for proper evaluation and treatment.
