Axon Optics offers a 30 day return policy so customers can test our product for a trial period. Whether you have perfect vision or need prescription lenses, we recommend first trying our non-prescription lenses in one of our frames to be sure the lens helps you before investing in a nonrefundable custom order. One week is the perfect amount of time to try out our lenses. If they haven’t worked after one week, they aren’t likely to help you. Keeping them for more than one week increases the likelihood of the glasses taking wear damage, much like a pair of shoes. We can only accept the return of glasses that are in mint condition, so please take good care of the glasses prior to returning them. While we advise not trying them for more than one week, you have a full 30 days from the date of purchase – please ensure they have been returned to us before the 30 days have passed.
You can find additional information, our full return policy, and our return form on our FAQ page at http://www.axonoptics.com/natural-migraine-relief-help-faq/
Please let me know if you have any other questions.
