Visual comfort probability

Visual comfort probability is a way to measure how comfortable your eyes will feel when looking at something. Imagine you're playing with your favorite toy and it's too bright, it might hurt your eyes and make them feel uncomfortable, right? Visual comfort probability helps to make sure that what you're looking at won't hurt your eyes or make them feel uncomfortable.

Scientists came up with a way to measure how bright something looks to our eyes. They realized that the more light there is in a room or on a screen, the less comfortable your eyes will feel. So they created a formula to measure the level of visual comfort probability in a given environment.

This formula takes into account factors like the brightness of the light source or the surface you're looking at, as well as the size of the object and the distance between you and the object. By estimating all of these things, we can determine how comfortable our eyes will feel when looking at an object.

Think of it like Goldilocks testing out chairs: if a chair is too big or too small, she won't feel comfortable. But if it's just the right size, she'll be happy and comfortable. In the same way, visual comfort probability helps us find the "just right" level of brightness and size for our eyes, so we can enjoy what we're looking at without discomfort or eye strain.
