Historical Significance: Review of Optometry Jan-Feb1991 describes Prentice as the 'Father of Optometry' because of his pioneering studies of optics and advocacy of optometry. He was trained as a mechanical engineer in Germany but his father, James, was an optometrist, trained in England. Charles Prentice described the law of decentration in 1890. He was highly regarded 'refracting optician' and one of the first to charge a fee for refraction but he was not loved by ophthalmologists. He lobbied unsuccessfully for registration of optometrists in New York in1896 and persuaded Columbia University to establish an optometry course in 1910. The American Academy has a lecture in his honour. The Keystone Publishing Company published a journal called the 'The Keystone' which was the organ of the Jewelry and Optical Trades.
