Ill start by saying that the ethics and legality of the online sellers is always questionable because their eyeglasses are always off. There is no way to have perfect eyeglasses without assistance in the measurement and selection of frames, lenses and coatings. Progressives lenses and lined bifocals need to be adjusted to make them perfect and online cannot do that. Finally, they have no quality standards because they do not measure the segment height of progressives or match base curves or do any real suggestion as to the needs of the patient. They are simply robbing the public that is unaware of the importance of the measurements.Yes they are denying the public of the services required to make a perfect vision required instrument that is a prescribtion. Them Thiefs....onliners.
