This is an antique Ophthalmoscope / Optometrist Eye Scope used to prescribe corrective glasses. Original design of this instrument was by W.H. Wollaston in 1870. It is in good condition with markings Concave, ConVex and exact increments for prescription based on how the view is focused. The adjustable focus view is stamped “Count The Dots”. Below Count The Dots are two sets of tiny dots. The squinting patient would adjust this slide until they could see the dots. This amazing old Machine would then register the prescription for each eye. Optics are in good condition as is brass nickel plated extension. The Bennion book shows W.H Wollaston’s original model of Boxwood & Brass that dates to 1870. Later in 1875, all brass models were manufactured. Size 12” x 3.5”. This is an incredible display for Optometrist’s to show early history eye examining compared with today’s modern methods.
