It sounds self-serving when we warn people about internet lenses, but we see the problems they cause far too often. It’s important to remember these are medical devices that require professional fitting and regular monitoring. The ironic thing about Hubble is their lenses are made from old technology that I haven’t actively prescribed in years and their pricing isn’t great, especially given the outdated material. Hubble was created for one rea$on. They are expert marketers; I’ll give them that.
