How Does a Magnifying Glass Make Things Look Bigger?
A magnifying glass enlarges an object’s appearance by bending the light rays that filter through it, thus distorting the size of the image formed, making it appear bigger.
A magnifying glass is a glass lens that is thicker in the middle than it is on the edges. The curved glass spreads out the rays of light so that they are wider apart when they get to your eye. This makes objects look bigger than their actual size, and you are able to see a lot more detail than you would otherwise.
Most hand-held magnifying glasses double the size of objects. In essence, magnifying glasses trick your eyes into seeing something differently than it really is. People began making magnifying glasses in the 1200s as an aid for reading.
