Auto Refractometer / Keratometer is a computer-operated machine used in eye measuring to measure a person’s vision, estimate refractive error, and figure out their glasses or contact lenses prescription. It does this by checking how light bends when it goes into the eye. It helps doctors to provide proper glasses or contact lens prescriptions.
Autorefractor are tools used to check how much vision correction someone needs. They are particularly useful for identifying different types of vision errors in the eye’s lens and cornea, and for checking patients before and after vision correction surgery.
The autorefractor shines light into your eye and measures how it changes after reflecting off the back of the eye (the retina). You’ll then see an image that goes in and out of focus. The machine takes multiple measurements to figure out when your eye is properly focused.
During the test, the patient looks at a fixed image, like a hot-air balloon floating over land. Like many eye exam tools, autorefractors can measure vision needs within a wide range, from -30 to +25 for spherical errors and up to ±10 for cylindrical errors.
Sometimes, autorefractor and keratometer, which measure the curvature of the eye’s surface, are combined into one device, but their measurement ranges can differ. It’s important for customers to know whether a device can perform both functions and what the specific ranges are for each.
The Eyevis Model RM-9200 is a simple device that measures the refractive error of your eyes, essentially helping to determine the correct prescription for your glasses or contact lenses.
This touch screen device automatically fine-tunes itself to ensure it provides precise readings, making it a reliable option for eye care professionals who need fast and accurate results during eye exams. With this device, the process of testing your vision and finding the right lenses for you is quicker and more efficient.

The Auto Ref-Keratometer K-900 and Auto Refractometer R-800 deliver accurate and reliable results. They have a classic, compact, and easy-to-use design, making them comfortable for eye-care professionals.
The K-900 serves as both a keratometer and an automatic refractometer, letting eye-care professionals check the curvature of the cornea and vision errors at the same time, making patient check-ups quicker and more efficient. The R-800 is specifically designed for refractometry and is excellent at precisely figuring out the needed prescription for glasses or contact lenses.
