Which of the following is NOT a vision insurance company?

In the context of vision insurance, the correct response identifies a company that does not primarily focus on providing vision coverage. HealthNow is primarily known as a health insurance provider but does not specialize in vision insurance like some of the other options listed.

On the other hand, Blue Vision, March Vision, and VSP (Vision Service Plan) all operate specifically in the realm of vision insurance, offering plans and services aimed at helping members manage their vision care needs. This distinguishes HealthNow from the others, confirming that it is not categorized as a vision insurance company. Understanding the focus of these companies on vision care is crucial for identifying which one primarily deals with vision insurance services.
