How does a magnifying glass work

A magnifying glass is simply a convex lens meant to be held up to an object to see it magnified. This shape bends the light waves of objects viewed through it, causing us to see them in unusual ways. When you hold a magnifying glass close to an object, its light waves are widened before they are focused on your eyes, causing the object to appear very large. But when you hold a magnifying glass out and view a distant object with it, the item appears smaller and upside down. This effect is due to the image being beyond the focus of the lens. The more curved a convex lens is, the greater its ability to bend light and magnify.
