Optography
in optics, the temporary retention in certain cases of an image, that of the last person or thing seen, on the retina of the eye when a man or a beast dies.
OPTOMETRY. The science of measuring the vision and strength of the eye without the dilation of the pupil by the use of drugs, and the selection of proper lenses to correct defective vision.
The use of drugs to dilate the pupils while making an examination is not legal, except by a registered physicianan oculist.
The profession of optometry has been established by those opticians who desired to place their work on a higher plane than that occupied by the ordinary seller of optical goods. An organization was formed in 1904, and committees appointed who worked for legislative regulation of the practice of their profession. Minnesota was the first state to acknowledge the new profession, but now almost every state, as well as the Canain common with other subjective symp-dian provinces, recognizes and regulates toms.
