Keratometer Optical Design

Keratometer

In this article, we will continue our description of different optical instruments used by optometrists. Last time we talked about Ophthalmoscopes, today we will talk about another very common optical instrument called the Keratometer. The keratometer was developed in 1851, it is used to measure the curvature of the anterior cornea. That is the outer […]

This will be the last entry in our series of optical instrumentation for optometry. If this is the first article that you are seeing, I would suggest that you take a look at our previous articles about Ophthalmoscope Design, Keratometer Design, and Retinoscopy. This week, we will talk about a very interesting optical device that […]
