My family business was started in 1936 by my Grandfather Leonard Maggiore Sr. in Bushwick Brooklyn. We have been in the mail order optical business since 1959 starting with prescription dive mask which my Dad Leonard Maggiore Jr. invented. We closed our brick and mortar store in 2007 and I work just mail order now. I started going to work with Dad in 1969. INTERNATIONAL SHIPPING AVAILABLE (with some exceptions).
