There is nothing wrong with physicians selling vitamins, orthopedic aids, medicines, eyeglasses, or any other medical devices from their offices, but they must comply with ethical business codes. Many patients enjoy the convenience of purchasing items at their doctor's office. Some physicians help their patients save money by making items available at nominal cost. Beware cautious when therapists suggest they are the only source of treatment. For example, the medical literature indicate acupuncture may be helpful in some eye conditions.
Acupuncture is widely available from certified acupuncturists across the country.
There is no need to travel across the country to receive acupuncture for the eyes. Check on the background of the therapist you choose. If the therapist has a PhD or claims to be a nutritionist, then inquire what kind of a degree they have and from what school. If the therapist indicates they offer treatment from a center or institute, inquire of the address and location of the place of treatment. Check on the business standing of the entity offering visual therapy.
