Children's glasses: When to renew to benefit from mutual reimbursement in 2026?

Your child's vision is evolving rapidly, and with it, the need to adjust their optical correction. As parents, it is legitimate to ask: “When can I renew their glasses to maximise the reimbursement from my mutual in Belgium?”

At Michils Opticians, located in the heart of Woluwe-Saint-Pierre, we know that your children's visual health is a priority. As contracted opticians, we are here to clarify the rules for 2026 and help you optimise each intervention.

1. The golden rule: The INAMI deadline vs The evolution of vision

In Belgium, reimbursement by the mandatory insurance (INAMI) is governed by specific rules for those under 18 years old:

  • Standard deadline: Renewal is generally scheduled every 2 years.

  • Early renewal: If your child's vision changes significantly, you do not need to wait these two years. A change in correction of at least ± 0.5 dioptre (sphere, cylinder or prism) justifies an early renewal covered by the INAMI.

Our role : As experts, we compare your old and new prescriptions to check if the medical conditions are met to benefit from this early intervention.

2. The accumulation with the complementary benefits of mutuals

Beyond the legal intervention of the INAMI, each mutual offers its own complementary benefits in 2026. These packages (which vary according to the insurance provider) can cover a significant part of the out-of-pocket costs for the frame or lenses.

  • Variable frequency : Unlike the INAMI, each mutual sets its own pace (sometimes annual, sometimes every 2 or 3 years).

  • Michils advice : It is common for your mutual's reimbursement period to be more flexible than that of the mandatory insurance. We help you check the specific conditions of your contract to avoid any unpleasant surprises.

3. Why choose a contracted optician like Michils Opticians ?

By choosing Michils Opticians for your child's equipment, you benefit from several decisive advantages :

  • Technical expertise : Our opticians-optometrists specialise in monitoring children's vision. Good equipment also means a perfect fit to ensure a calm visual development.

  • Administrative support : We manage the establishment of the annex 15 (certificate of delivery) for you, which is essential to trigger your INAMI and supplementary reimbursements.

  • Transparency : We provide you with the exact amount of the interventions you are entitled to before any order. You know your out-of-pocket expenses clearly.

  • Quality & Comfort : Our selection of frames combines durability and aesthetics, because a pair of glasses that a child loves to wear is a pair of glasses that does its job well.

4. The steps for renewal in 2026

To obtain your reimbursement easily, here is the procedure to follow :

  1. Consult your ophthalmologist : A recent medical prescription is required for any new delivery.

  2. Visit Michils Opticians : Come with your child for a frame selection and a visual check if necessary.

  3. Let us handle it : We prepare the necessary documents for your mutual insurance.

  4. Request your reimbursement : Simply send the detailed invoice and the certificate of delivery to your insurance provider via your member area or by post.
