Synopsis
This research, published in Health Affairs in August 2024, peer reviewed and funded by the National Eye Institute, is among the first full state-by-state reviews of how adult Medicaid programs cover routine eye exams, eyeglasses and low vision aids under both fee-for-service and managed care. Using 2020 enrollment data and 2022 to 2023 coverage policies, it found that 6.5 million adult enrollees lived in states that did not cover routine eye exams and 14.6 million lived in states that did not cover glasses, while seven states covered neither under any plan type. It matters because uncorrected refractive error is the leading cause of vision impairment in the United States, and poor vision raises the risk of falls, depression and loss of independence. The study is useful for people with disabilities, older adults on low incomes, advocates and state policymakers weighing benefit changes.*
At a Glance
- 1 - Two-thirds of states required enrollees to pay part of the cost.
- 2 - Thirty-five states did not cover low vision aids such as magnifiers and loupes.
- 3 - Maine covered glasses only once in a lifetime and only for very strong prescriptions.
- 4 - An uninsured adult can pay around $485 for an eye exam and glasses, more than a third of monthly income at the poverty line.
Topic Definition
- Medicaid Adult Vision Benefits
Medicaid adult vision benefits are the optional eye care services that a state Medicaid program may cover for enrollees aged 21 and older, such as routine eye exams, eyeglasses, contact lenses and low vision aids. Federal law requires vision care for children in Medicaid, but for adults each state decides which services to cover, how often, and what copays apply, so benefits differ from state to state and between fee-for-service and managed care plans.
Overview
A study supported by the National Institutes of Health (NIH) shows that 6.5 million Medicaid enrollees (12%) lived in states without coverage for routine adult eye exams; and 14.6 million (27%) resided in states without coverage for eyeglasses. The study based on 2022-23 coverage policies, published in Health Affairs, is among the first to provide a comprehensive, state-by-state analysis of adult Medicaid benefits for basic vision services in both fee-for-service and managed care.
Medicaid provides health coverage to millions of Americans, including eligible low-income adults, children, pregnant women, elderly adults and people with disabilities. While the federal government establishes overarching rules for Medicaid, each state runs its own program, including determining eligibility and coverage policies. The law allows states to determine coverage of eye exams and eyeglasses for adults. It is important to note that for children, federal law entitles Medicaid-enrolled infants, children, and adolescents to Medicaid coverable, appropriate, and medically necessary services needed to correct and ameliorate health conditions, including vision services.
"Our study clearly shows that there are opportunities to expand coverage of routine vision services at the state level, and based on previous research, we expect more generous coverage would reduce rates of vision impairment, improve quality of life, and promote health equity," said Brandy Lipton, Ph.D., study author and associate professor of health, society and behavior at the University of California, Irvine.
Exams conducted by an eye care provider are the only way to detect eye diseases early, when treatment has the best chance to prevent vision loss. Exams are also essential to obtain a prescription for glasses to correct refractive error, the leading cause of vision impairment that affects more than 12 million people in the U.S.
The analysis of 2020 Medicaid enrollee data, and 2022-23 coverage policies, shows that state-level coverage for adults varied widely; gaps in coverage included:
- In 20 states, fee-for-service Medicaid policies did not cover glasses at all; and in 12 of those states, eye exams were also not covered.
- Seven states had no coverage for exams or glasses under both fee-for-service and managed care policies (Arizona, Idaho, New Mexico, Oklahoma, Tennessee, West Virginia, and Wyoming).
- Thirty-five states did not cover low vision aids such as magnifiers and loupes.
"Visual impairment can be corrected with glasses in most instances, but not all. Particularly among older adults, lack of coverage for low vision aids may be an important gap," said Lipton.
Moreover, even in states that had coverage for vision care services, copays and restrictive policies could still be a barrier for enrollees following through on an exam or glasses. Fully two-thirds of states required enrollees to cost share.
Medical Expenditure Panel Survey data show that out-of-pocket expenses for an uninsured adult for an eye exam and glasses can cost around $485, which is more than a third of the monthly income for a single adult living at or below the federal poverty level.
Maine had the most restrictive glasses coverage policy, where glasses were covered only once per lifetime, and only for people who required an unusually strong prescription to correct their vision.
Previous research shows that vision impairment can increase the risk of falls and hip fractures, difficulties performing activities of daily living, social isolation, depression, cognitive impairment and mortality.
"Reducing disparities in vision care is a powerful way to improve quality of life for everyone. This study points to opportunities for expanding coverage to reduce inequities in basic vision care for people with lower incomes," said Michael F. Chiang, M.D., NEI director.
With the aging of the U.S. population, the number of people with vision impairment from all causes is expected to double by 2050.

Frequently Asked Questions
NOTE: Researched FAQs by Disabled World (DW)
Does Medicaid cover eye care for medical conditions like glaucoma?
Yes, treatment of eye diseases such as glaucoma, cataracts and diabetic eye disease is usually covered as medical care, even in states that do not cover routine exams or glasses.
Does Medicare pay for eyeglasses?
Original Medicare generally does not pay for routine eye exams or glasses, except for one pair after cataract surgery with an intraocular lens. Many Medicare Advantage plans add some vision benefits.
Can a Medicaid managed care plan cover more than the state requires?
Yes, some managed care plans offer extra vision benefits beyond the state program, such as an annual exam or an allowance for frames. Enrollees should check their plan documents.
What are low vision aids?
Low vision aids are devices that help people make the most of remaining sight, including magnifiers, telescopic lenses, electronic video magnifiers and special lighting. They are often recommended after an exam by a low vision specialist.
How often should adults have an eye exam?
Many eye care professionals advise a full exam every one to two years for adults, and yearly exams for people with diabetes or those over 60. Your eye doctor may suggest a different schedule.
Where can people without vision coverage get help paying for glasses?
Options include community health centers, nonprofit programs such as those run by Lions Clubs, and some optometry schools that offer lower-cost clinics. Local social services offices can point to programs nearby.
Does Medicaid vision coverage change often?
Yes, states can add or cut optional adult benefits when they set their budgets, so coverage may change from year to year. Checking the state Medicaid website before an appointment is wise.
Are people with disabilities more affected by vision coverage gaps?
Many disabled adults rely on Medicaid and may already face barriers to transportation and care. A missing benefit for glasses or low vision aids can have a larger effect on their independence and safety.
Insights, Analysis, and Developments
Editorial Note: Children enrolled in Medicaid are guaranteed vision care under federal law, but that promise ends at age 21, leaving adult eye care to each state to decide. The result is a patchwork in which the same person could have exams and glasses covered in one state and nothing in the next. Because vision loss is expected to double by 2050 as the population ages, these gaps are likely to matter more each year, especially for disabled and older adults who depend on Medicaid. Anyone enrolled should check their state Medicaid handbook or managed care plan, since some plans offer vision extras that the state program itself does not.*
