Understanding the Autorefractor
What is an Autorefractor?
An autorefractor is an ophthalmic device used to measure the refractive error of the eyes automatically. The autorefractor shines light into the eye and measures how it changes as it bounces back off the retina. This process provides an objective measurement of refractive error, which can then be used to prescribe corrective lenses.
They are essential in determining the degree of nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. These devices offer quick and reliable measurements, making them invaluable in both clinical and retail optometry settings.
Historical Development of Autorefractors
The development of this machine began in the mid-20th century, with early models providing basic measurements of refractive error. These devices have evolved significantly, incorporating advanced optics and digital technology to improve accuracy and ease of use.

Function and Use of Autorefractors
How an Autorefractor Works
An autorefractor operates by projecting a light beam into the eye and analyzing the reflection off the retina. The device measures the amount of light reflected back and calculates the eye’s refractive error. This process is quick, typically taking just a few seconds per eye.
The patient looks into the autorefractor at a target image, which helps the eye maintain a steady focus. The device then automatically adjusts to measure how light is altered as it travels through the eye, providing an accurate assessment of refractive error.
Steps in Using an Autorefractor
- Patient Preparation: Ensure the patient is comfortably seated and positioned correctly.
- Focusing: Align the autorefractor with the patient’s eye, having them focus on a target image.
- Measurement: The autorefractor projects light into the eye and captures the reflected light to measure refractive error.
- Results Interpretation: The device provides a printout or digital readout of the refractive measurements.
Optometrists use these measurements as a baseline for further subjective refraction tests using a phoropter or trial lenses. The quick and automated nature of autorefractors enhances the efficiency of eye exams.
