VSP Optics Group is introduced otto (one touch to optical), a new app that serves as an eyecare practice’s virtual optical assistant, at International Vision Expo West last week. Otto is designed to function as an easy-to-use app for the second and third generation Apple iPad that helps eyecare professionals (ECPs) simplify measuring and dispensing advanced digital lenses, and brings eyewear consulting, electronic claim filing, and more to the point-of-care.
