It is possible to have frames purchased from other retailers (non-JINS) filled with prescription lenses. However, this service is available in-store only and acceptance of your frame is up to the discretion of a manager on site. (Due to material and/or condition, not all frames may be accepted.)
Pricing for non-JINS lens exchanges are $50 per lens plus the price of the lenses of your choice.
Please refer here for lens replacement for JINS glasses.
