Thank you for your feedback! I’m glad to hear you’re enjoying the lenses, but I’m sorry about the issue with the arm breaking. That’s definitely not what we’d expect. If you haven’t already, feel free to reach out to us at online@brighteyes.com.au or return them to the store your purchased them from with proof of purchase. They can be assessed in regards to the breakage. We’d love to help you find a more permanent solution. Your satisfaction is important to us!"
