👀 The direction a lens faces really matters, and flipping one around could make its ability to focus light way worse. But why?

💡One of the biggest reasons is spherical aberration

🔎 Spherical aberration is an optical defect that occurs when light rays passing through the edges of a curved lens or mirror refract (bend) at different angles than rays passing through the center

🌠 Because they do not converge at a single focal point, the resulting image appears blurred or softened

🔎 Flipping a lens around can change the amount of spherical aberration, as described in this video
