Retail sales in the sunglasses market rose from $361 million in 1985 to $1.5 billion by the end of the decade, reflecting a 100 percent increase from 1980.
the increase in sales was partly attributable to the popularity of several films during the early 1980s that featured well known actors wearing sunglasses.
In 1998, sales of sunglasses equaled $1.9 billion, with mass retailers accounting for $262 million, optical outlets $406 million, and sunglasses specialty stores $495 million.
During the 1960s, sunglasses became fashionable accessories worn throughout the year and were no longer considered seasonal products.
