Warranty policy

Last updated: September 21, 2026

This policy explains the limited commercial warranty LEION provides for qualifying products bought from leion.glass or an authorized LEION seller. It applies in addition to your consumer rights under applicable law. Where the law gives you a longer or broader protection, that protection continues to apply.

1. Warranty periods

  • LEION Hey2: one (1) year from the date the product is delivered to you.
  • LEION Hearing: two (2) years from the date the product is delivered to you.

If products or prescription lenses in one order are delivered separately, the applicable period for each item begins on its own delivery date. Please keep your order confirmation or other proof of purchase.

2. What the warranty covers

During the applicable warranty period, this policy covers defects in materials or workmanship that prevent a LEION product from working as intended under normal use.

For prescription lenses processed by LEION for Hey2 or LEION Hearing, the applicable model warranty also covers a confirmed lens manufacturing or processing error attributable to LEION. For example, if LEION makes the lenses to values different from the prescription or measurements you confirmed, contact us for review. The warranty does not treat an incorrect value supplied or confirmed by the customer as a LEION processing error.

After reviewing a covered claim, LEION will provide an appropriate remedy in accordance with applicable law and this policy. Depending on the issue, this may include repair, reprocessing or replacement of the affected product or lenses, or a refund where required or appropriate.

3. What is not covered by this commercial warranty

Subject to any rights that cannot be excluded under applicable law, the limited warranty does not cover:

  • Prescription, pupillary distance (PD), fitting measurements or other order details that you entered or confirmed incorrectly, or a prescription that changes after the order;
  • Personal preferences or concerns about fit, comfort, appearance or adapting to correctly made prescription lenses, where there is no product defect or LEION processing error;
  • Damage caused by an accident, misuse, neglect, improper storage, use contrary to product instructions, or unauthorized repair or modification;
  • Normal wear and tear or cosmetic marks that do not affect the product’s function.

These exclusions do not apply where the problem was caused by LEION or where applicable law requires a remedy.

4. Prescription lens cancellations and returns

Please check all prescription and measurement details before submitting your order. Custom prescription lenses may be cancelled before processing begins. Once processing or fabrication has begun, the custom lens item and any product sold as an inseparable package with it cannot be cancelled, returned, exchanged or refunded for a change of mind, customer-entered prescription or measurement error, a later prescription change, personal fit or comfort, or adaptation preference. This does not apply if LEION made an error, the product or lenses are defective, or applicable law requires another remedy.

For the full cancellation and refund rules, including the return period for eligible non-custom products, see our Refunds, Returns & Order Cancellation Policy.

5. How to make a warranty claim

  1. Email support@leion.glass with your order number, product model, delivery date and a description of the issue.
  2. Include clear photos or a short video if they help show the problem. For prescription lens claims, include the relevant order details so we can compare the lenses with the values confirmed at checkout.
  3. Wait for our reply and return instructions before mailing a product or lenses to us. We will explain any inspection or shipping steps before you send anything.

We may ask for additional information or inspect the product to determine whether the issue is covered. If a claim is not covered, we will explain the reason and any available options or charges before proceeding.

6. Consumer rights

This limited commercial warranty is provided in addition to consumer rights and remedies that apply to your purchase. Nothing in this policy excludes or restricts a guarantee, remedy or right that applicable law does not allow LEION to exclude or restrict. The warranty periods above do not shorten any longer protection required by law.
