Green eyeshade

Type of visor

Green eyeshades or dealer's visors are a type of visor that were worn most often from the late 19th century to the mid-20th century by accountants, telegraphers, copy editors, and others engaged in vision-intensive, detail-oriented occupations to lessen eye strain due to early incandescent lights and candles, which tended to be harsh. Because they were often worn by people involved in accounting, auditing, economics, and budgeting, they became associated with these activities.
