Why Do I See Light When I Close My Eyes?
It’s a common experience: you close your eyes, expecting darkness, but instead, you’re greeted with a kaleidoscope of colors and lights. This phenomenon, known as “phosphenes,” is caused by the spontaneous firing of neurons in the visual cortex of your brain. When these neurons fire, they send electrical signals to your eyes, which interpret them as light.
Phosphenes can be triggered by both internal and external stimuli. Internal stimuli include pressure on the eyeballs, such as when you rub your eyes, as well as changes in brain activity, such as those that occur during migraines or seizures. External stimuli include bright lights, which can overstimulate the retina and cause phosphenes to appear.
Types of Phosphenes
There are two main types of phosphenes: simple and complex.
Simple phosphenes are brief flashes of light that are typically seen in the periphery of your vision. They are often caused by pressure on the eyeballs or by changes in brain activity. Complex phosphenes are more elaborate and can include shapes, patterns, or even faces. They are often associated with migraines or seizures.
Causes of Phosphenes
The most common cause of phosphenes is pressure on the eyeballs. This can occur when you rub your eyes, when you cough or sneeze, or when you wear tight-fitting glasses. Other causes of phosphenes include:
- Changes in brain activity, such as those that occur during migraines or seizures
- Eye injuries
- Certain medications
- Drug use
- Vitamin deficiencies
When to See a Doctor
In most cases, phosphenes are harmless and do not require medical attention. However, if you experience phosphenes that are:
- New or sudden
- Accompanied by other symptoms, such as headache, nausea, or vomiting
- Interfering with your vision
You should see a doctor as soon as possible to rule out any underlying medical conditions.

Expert Advice
