Visual optics

Historical Significance: This book covers an outline of the eye and vision, visual acuity, refractive errors, accommodation and convergence, ophthalmoscopy, retinoscopy, keratometry. There are 5 chapters on binocular vision and the two last chapters are on the schematic eye and aberrations of the eye. It was a standard optometry text in the UK and Australia from 1936 into the 1960s. Emsley was Head of the Applied Optics Department in the Northhampton Polytechnic within which an optometry course was taught, although the Polytechnic has now become City University and the Department is the Department of Optometry and Visual Science. Emsley held a BSc degree so the book tends to be quantitative although there is no hard maths.
