Dear Xingyu, we are sorry to hear that. As a general rule of thumb, the frames you choose should be the opposite of your face shape to offset your prominent features and create balance. We understand that choosing a perfect frame style online can be tough sometimes but can be easy as well. Follow the instructions and steps to get your fit pair. Please check face shape and frame style. You can also use the virtual try-on feature for style references and check how to measure frame size.  Moreover, our lenses that are treated front and back with a clear, scratch-resistant coating have a much harder surface that is more resistant to scratching, whether from dropping your glasses on the floor or occasionally cleaning them with a paper towel. But it is not to say the lenses can be anti-scratched under any situation such as it comes with harder objects. Please don't worry,  we would like to provide a big discount for you to buy a new pair since you are our cherished customer. Please kindly check your email within 24 hours. Thank you and have a great day ahead.
