Spring hinges are designed to make eyeglass frames more comfortable and enjoyable to wear, allowing people to wear them flexibly without caring too much about the size when choosing a frame.
The spring hinge design is more suitable for adults who love movement and freedom, as well as active children. Because the spring can better clench the head to ensure the safety of wearing, and increased security. Therefore, it is recommended to choose spring hinge glasses when available.
It is not recommended to fix spring hinges on eyeglass frames that have been damaged, if you are not an eyeglass professional. You can try asking at an optical store or come to ABBE Glasses to see the cheap and good spring hinge glasses.
