In 1821 the French physicist A.L. Fresnel invented a completely flat lens. Its surface is covered with concentric grooves that refract the light. Nowadays they find wide use e.g. in light houses and overhead projectors. Nevertheless they seem to disagree with everyday experience and baffle kids and adults alike. The Fresnel lenses F-52 and F-53 are well suited as magnifying glasses for reading small text. They are also great bookmarks.
