I think we all know that moment when we rub our eyes and suddenly, certain patterns and colors appear. How do these happen and does it have any effect on our eyes?
In: Biology
When you rub your eyes, you’re putting gentle pressure on them. Inside your eyes, there are special cells called photoreceptors that help you see things. When you press on your eyes, it can kind of squeeze these cells a bit, and they might send funny signals to your brain. These signals can make you see colors and shapes that aren’t really there.
