This often happens in New Age lifestyles, becoming so common one would think the new age has already left a mark on the mainstream! At one time before the New Age lifestyle silently, without any fanfare, changed western society, the outcome of interaction was: someone wins and the other loses.
According to vision insurance provider Vision Service Plan Direct, the national average price as of June 2015 of a comprehensive eye exam without insurance is $154. The latter does not include frames, prescription lenses or optical lens enhancements.
Even with great insurance, I still have to pay $40 out-of-pocket for my lens fitting fee (that was at Target) ...add the $40 to a typical $50 charge for an exam and voila! you have almost $100! You can't simply get a regular eye exam and then ask the doctor to write you a contact prescription.
