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...
Retinoscopes are a very common optical instrument used by optometrists to examine a patient’s eye and evaluate the need of corrective lenses. They use a very interesting physical principle. Let’s first describe the optical instrument. The retinoscope is a hand held...
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 the next couple of articles, we will talk about the different instrumentation used by ophthalmologists and optometrists. As you can imagine, there are many restrictions when designing an optical instrument that will be used in a patient. It matters whether the...
