This site is a scam site. The agents answering the phone are actually in India, not in the U. S as they claim. They also do not know anything about the products they sell. For example, I asked them some testing questions. I asked if their eye treatments helped with peristalsis, (which is a digestive function and has no relation to optometry whatsoever) and if my tendons connect my bones (the correct answer being "no", as tendons connect muscle to bone. Ligaments connect bone to bone). To these questions, they answer yes, which displays their lack of knowledge in any of the medical fields.
