Vision insurance is a type of health insurance that helps cover the costs of eye care. This can include routine eye exams, glasses, and contact lenses. It may also provide coverage for certain eye diseases and treatments, depending on the specific plan. Most vision insurance plans require a monthly premium and may have a deductible. They often include a network of eye care providers, so it's important to choose an in-network provider to maximize benefits. Overall, vision insurance can help reduce out-of-pocket expenses for maintaining good eye health.
