Expenses for vision services, such as an eye exam, are relatively small, yet they are often included as a health insurance benefit because of this:
A. Employers want to ensure that their employees’ productivity would not be adversely affected by poor vision.
B. The price of vision benefits is reduced by tax-exempt employer insurance.
C. Eyesight is an essential need for people, and good eye care is worth paying for.
D. Similar to dental services, vision services should be part of a comprehensive insurance policy.
