Vernonscope LLC manufacturers Brandon Eyepieces and other high quality optical accessories.


The Brandon lens design was invented in 1949 by Chester Brandon.  Don Yeier founded VERNONscope in 1958.  In 1962, Don Yeier purchased the designs from Mr. Brandon. For over 50 years, Mr. Yeier built Brandon eyepieces and other optical accessories in Candor, NY. In 2013, Mr. Yeier sold the company to Tony and Liz Mansfield, who continue to build Vernonscope products, including the Brandon eyepieces, under the company name of Vernonscope LLC.
