Magnifying glass. The glass lens is polished to an exact shape to produce a clear image. It magnifies the view of an object because the shape of the lens is convex,refracting light from an object to make it appear bigger. The lens has a focal point,and the magnifying glass has to be held at the correct distance from the object to obtain a clear and focussed image | |
