Practical Remarks on Near Sight, Aged Sight, and Impaired Vision: With Observations Upon the Use of Glasses, and on Artificial Light

Practical Remarks On Near Sight, Aged Sight, And Impaired Vision: With Observations Upon The Use Of Glasses, And On Artificial Light by William White Cooper. This 1840s ophthalmic treatise offers a comprehensive, accessible survey of how sight changes with age and disease, and how spectacles can aid or impair vision. Cooper explains the anatomy and physiology of the eye—cornea, lens, iris, retina, and optic nerve—and then treats disorders such as myopia (near-sight) and presbyopia (aged sight) with clinical observations, illustrations, and case histories. A central focus is the practical use of glasses: selection of lens types, focal lengths, frame fit, and cautions against unnecessary changes or overuse, with extensive discussion of concave versus convex lenses and the special needs of cataract patients. The book also examines artificial light’s effects on the eye, with strategies to reduce irritation, improve ventilation, and minimize glare. Rich in early ophthalmic knowledge and patient-oriented guidance, it remains a notable historical resource on vision care and optical instruments.
