Our business could be adversely affected by the availability of vision correction alternatives to prescription eyeglasses.
Our business could be negatively impacted by the availability and acceptance of vision correction alternatives to prescription eyeglasses, such as contact lenses and refractive optical surgery. According to industry estimates, over 40 million people wear contact lenses in the United States, and disposable contact lenses is the fastest growing segment of the lens subsector. In addition, the use of refractive optical surgery has grown substantially since it was approved by the U.S. Food and Drug Administration in 1995.
Increased use of vision correction alternatives could result in decreased use of our prescription eyewear products, including a reduction of sales of lenses and accessories sold in our retail outlets, which would have a material adverse impact on our business, results of operations, financial condition and prospects.
