Don't waste your time or money! My daughter paid for glasses with a blue light filter on them. Upon receiving them, we could tell her glasses did not have this feature. Talked To go optic, They insisted they did. Took it to three different optometrists That in fact confirmed that it DID NOT contain the blue light filter. Sent Go Optic documentation and they still denied the claim for a refund, or even to fix them! So much for customer satisfaction. The worst customer service ever.
