How can you tell how old a pair of glasses is?

To tell how old a pair of glasses is, you can examine it closely and then conduct some research using trusted online resources. If you see a mark that indicates the maker, use the manufacturer as a starting point. Find out when the company was in business and look at catalogues and other references to determine when it produced similar styles. If you can't find a maker, your glasses will likely be from the late 20th century or earlier. In this case, you can research the characteristics of your glasses to get a rough idea of the age. For example, nose pads didn't come into use until the 1920s. Another feature of eyeglasses introduced in the 1920s is positioning the temples at the upper corners of the frames rather than in the middle.
