Understanding The Importance of Tonometry for Vision Insurance Coverage

When it comes to maintaining proper eye health, regular eye exams are an essential part of the process. One important aspect of these exams is tonometry, a test that measures the pressure inside the eye, which can help detect certain eye conditions. However, many people may be unaware that not all vision insurance plans cover this test.

Most individuals with vision insurance assume that all eye exams and treatments are covered, but that’s not always the case. It’s important to understand what your specific plan covers to avoid unexpected costs and ensure proper eye care.

The Importance of Tonometry Test

High pressure inside the eye, known as intraocular pressure (IOP), can be a sign of glaucoma, a leading cause of blindness. Tonometry is a quick and painless test that measures IOP by using a small device to gently touch the surface of the eye or a puff of air directed at the eye. The results of tonometry can help your eye doctor diagnose glaucoma or monitor the condition if you have already been diagnosed.

Vision Insurance Coverage for Tonometry

Not all vision insurance plans cover tonometry, so it’s important to check your specific plan details. Some plans may cover the test once a year for those considered at high risk for glaucoma, while others may only cover it if you have already been diagnosed with the condition. Additionally, some plans may only partially cover the cost, leaving you responsible for a co-pay or deductible.

If your plan does not cover tonometry or you don’t have vision insurance, the out-of-pocket cost can vary. According to CostHelper Health, the average cost of a tonometry test is around $55 but can range from $10 to $200 depending on location and other factors.

Getting the Most Out of Your Vision Insurance

To ensure you are getting the most out of your vision insurance plan, it’s essential to understand exactly what is covered and what is not. Take the time to review your plan details or speak with your insurance provider to avoid unexpected costs and ensure proper eye care.

  • Know your coverage: Check your plan details to understand what vision care services are covered and any limitations or restrictions.
  • Ask questions: If you’re unsure about the specifics of your coverage, reach out to your insurance provider to clarify.
  • Find in-network providers: To maximize your benefits, make sure to visit an eye doctor who accepts your insurance plan.
  • Consider additional coverage: If your current plan doesn’t cover a specific test or treatment, consider additional coverage or upgrading your plan to better fit your needs.


Tonometry is an important tool for maintaining proper eye health, but not all vision insurance plans cover the cost. To avoid unexpected costs and ensure proper eye care, it’s essential to understand your specific plan details and ask questions if needed. With proper understanding and research, you can ensure that you’re taking the best possible care of your vision.
