The story of optics goes long back in the past. The oldest instance of
glass being used as a tool of magnification is over 4000 years old.
Glasses were first used as magnifiers and then used as optical aids
for people with poor vision. For the purpose of spectacles, several
refinements had to be made. But magnifiers have been around for a long
time helping people by making the finer details clearer. A combination
of such lenses gave us the microscope and the telescope. Thus
magnifying glasses are important in almost all walks of life.
