Most people see splashes of colors and flashes of light on a not-quite-jet-black background when their eyes are closed. It’s a phenomenon called
phosphene
What is normal to see when you close your eyes?
These phenomena visible to the closed eye might include white blood cells within the capillaries around the part of the retina called the fovea, which pulsate with one’s heartbeat; white dots with tails;
floaters and vertical or horizontal lines
.
Why do I see purple in my vision?
Cones are the cells in the eyes that see color. If you stare at one color for too long, they fatigue. Until they recover, it’s a common optical illusion to see the opposite color on the color wheel. So,
staring at yellow for too long
can make you see purple.
What do blind people see?

like macular degeneration.
What is Charles Bonnet syndrome?

What are the warning signs of a detached retina?
- The sudden appearance of many floaters — tiny specks that seem to drift through your field of vision.
- Flashes of light in one or both eyes (photopsia)
- Blurred vision.
- Gradually reduced side (peripheral) vision.
- A curtain-like shadow over your visual field.
Who gets Charles Bonnet syndrome?
CBS is more common in
people aged 80 years and above
