NEW YORK—There was a higher concentration of sales among the 2019 VM Top 50 U.S. Optical Retailers, which assesses estimates of 12 months of calendar sales for the year ending Dec. 2018. The Top 10 optical retailers collectively comprise 87.5 percent of the Top 50 U.S. optical retail sales. That equated to a collective-estimated $12.6 billion out of the market’s total optical retail sales of $35.7 billion, as reported by VisionWatch/The Vision Council.

In 2018, the Top 50’s share of the total market just exceeded 40 percent. Mass merchants were an estimated 24.4 percent of the top 50.
