The refractometer measures the amount of light shift, called the angle of refraction. This refraction is converted to a useful unit of measure. With saltwater refractometer, the units are specific gravity and salinity. By looking through the eyepiece, you’ll see the measurement scale indicating salinity and specific gravity. A refractometer is a device used to measure the refractive index (n) of a substance. This physical property can be used to make a variety of assessments, such as to determine the purity of a substance (by comparing its n value with a standard value) or to assist in identifying an unknown substance by comparing its n value to reference values. 1In some offices, this process is used to provide the starting point for the ophthalmologist or optometrist in subjective refraction tests. Here, lenses are switched in and out of a phoropter and the patient is asked "which looks better" while looking at a chart. This feedback refines the prescription to one which provides the patient with the best vision. How to Use a Refractometer: Types of Refractometers.
