Insurance Basics: Home
Health insurance protects you from paying the full cost of your care. But, you will likely still have to pay some money out of your pocket. Almost all plans call for “cost sharing”. That means your insurer pays for part of your care, and you pay for part.
Your health insurance ID card is your proof of insurance. You use it when you visit the doctor, hospital or other provider.

Most health plans cover medically necessary visits to an eye doctor. Sometimes they cover routine eye exams too, but to get complete vision coverage you may have to go to other sources. This article will tell you about those sources.
