Among the items from the Ericsson estate were his personal spectacles. The spectacle lenses have many different powers. This implies that John saved his old spectacles even when newer ones were fitted to his modified visual power. The varying strengths suggest that John Ericsson probably became more and more far-sighted, which is a normal occurance. The blue spectacles are John Ericssons sun glasses. All the spectacles are from 1870-1889. <br /><br />Photo: Mats Landin ©Nordiska museet Among the items from the Ericsson estate were his personal spectacles.
