The erratic reflected light mixes with usable light, detracting from the image. (This is called diffusion.) Lens coatings seek to eliminate this ph ...

How to use an Ophthalmoscope
... All direct ophthalmoscopes house a carousel containing up to 20 lenses. Each lens can be rotated into the viewing aperture (Fig 1). The ‘positive’ lenses (typically with black dioptre indicators 1-10) are increasingly convex. Hence the higher number lenses bring the focus closer to the operators ...
