{"response":"{\"What is spherical aberration?

Spherical aberration is when light bends wrongly through a curved surface, like a spoon or a lens.

Imagine you're looking at a spoon in the kitchen. If you hold it up to your eye and look through it, things might appear blurry or stretched out, not because the spoon is broken, but because of how light travels through its curve.

Think of the spoon as a lens. When light goes through it, different parts of the spoon bend the light in slightly different ways. Light that hits the middle of the spoon bends one way, while light that hits near the edges bends another way, like kids playing tag and running off in different directions.

This makes the image you see a little out of focus or distorted, just like when you try to look through a magnifying glass at an angle and everything looks funny.

It’s kind of like watching a movie on a curved screen. If the screen is too curved, parts of the movie might seem closer or farther away than they should, not because the screen is broken, but because of how light moves through it.
