Photosensitivity in humans

Hey there! I heard you want to learn about photosensitivity in humans. Well, photosensitivity is when a person's eyes or skin are sensitive to light.

Let me explain it a bit more. Our eyes are really important organs that help us see everything around us. But sometimes our eyes can be very sensitive to light. Have you ever been in a really bright room and felt like you had to squint or close your eyes? That's because the light was too bright for your eyes to handle.

Photosensitivity can also affect our skin. Just like our eyes, our skin can be sensitive to light too. You know that feeling when you've been outside in the sun all day and your skin starts to burn or turn red? That's because your skin is sensitive to the light from the sun.

Certain medications or medical conditions can make a person more photosensitive, which means they can have a stronger reaction to light. Some people need to take extra care to protect their skin and eyes from sunlight if they are sensitive to it. Sunscreen, hats, and sunglasses can all help protect your skin and eyes from the harmful effects of the sun.

So, in summary, photosensitivity is when a person's eyes or skin are sensitive to light, and it can be caused by medications or medical conditions. Protecting your skin and eyes from sunlight can help if you are photosensitive.
