Hey there! So, have you ever seen those really big umbrellas that people use to protect themselves from the sun? They're called parasols. And just like how a parasol covers you and gives you shade, a parasol cell is a type of cell in our eyes that helps us see things that are really bright and shiny.
Our eyes have different types of cells, kind of like how a car has different parts that work together to make it go. One type of cell is the parasol cell, and it's really good at detecting bright, high-contrast things like shiny objects, headlights, or the sun.
The parasol cell is shaped kind of like a small umbrella, with a big round part at the top and a skinny part at the bottom. When light enters our eyes, it hits the parasol cell and makes it send a message to our brain that helps us see the bright object.
So, just like how a parasol protects us from the sun, parasol cells give our eyes protection from really bright lights and help us see things better!
