Most of the brands we carry come with a one or two year manufacturer warranty. This covers defects from manufacturing. If you have a suspected warranty claim please bring in the glasses to be inspected by our team at G is for Glasses. If you have purchased the glasses online please email us at hello@gisforglasses.com along with photos of the issues you are experiencing, we will get back to you asap with solutions. Warranties are void if the damage is caused by improper use or careless maintenance, regular wear and tear, incorrectly following the care instructions, having anyone other than G is for Glasses maintain the glasses, or if you have tried to fix them yourself before bringing them in to be looked at.
