Humans are more adapted to light mode because we spend most of our time in bright environments, like during the day.
Imagine you're playing outside on a sunny afternoon, that's like being in light mode. Your eyes get used to seeing everything clearly under all that light. Now think about when it gets dark and you go to bed, that’s more like dark mode. Your eyes need time to adjust, just like how your toys look different when the lights are off.
How our eyes work with light
Our eyes have special cells called rods and cones. Cones help us see colors and details in bright light, like when you're reading a book under the sun. Rods help us see in low light, like when it's nighttime or when you're in a dark room.
So while we can use dark mode, our eyes are used to light mode most of the time, just like how your favorite toy feels best when it’s bright and colorful!
Examples
- A child reads a book in the evening with no lights on
- An office worker uses a bright screen during the day
- A student prefers using their phone at night under a blanket
