Understanding Flashing Lights in Vision: 1 Minute to Identify the Causes and Solutions

Flashing lights in vision—often described as seeing sparks, flickers, or bursts of light—can be unsettling. Medically, these visual phenomena are called photopsia, and they may manifest as arcs, shimmering spots, or even pulsating flashes. Common causes include retinal stimulation, such as posterior vitreous detachment, migraines, or exposure to sudden bright light. Occasionally, the symptom signals something benign, like ocular fatigue after staring at screens. However, flashing lights can also mark serious issues like retinal tears or detachments, which require immediate medical attention.

Tips 1:

As a designer, I know how integral lighting is to both aesthetics and eye health in our living spaces. If you often experience discomfort due to lighting at home, carefully assess the arrangement, brightness, and type of fixtures. For example, indirect lighting can help reduce eye strain, while smart placement of task lights supports functional activities. For a personalized and efficient approach to your lighting setup, using a home designer tool can let you visualize and optimize ambient illumination, ensuring both comfort and beauty.
