Whether you’re about to embark on your first eye exam or haven’t been skipping an appointment, it’s always good to understand the tools of the trade. That knowledge can demystify the process and empower you to take charge of your ocular health. In this article, top eye care provider Northern Virginia Doctors of Optometry highlights common tools and equipment eye doctors used when conducting eye exams.
The phoropter is a tool with several sets of lenses used primarily for measuring refractive error and determining eyeglass prescriptions. The eye doctor switches between lenses while asking you to compare two images to decide which one is sharper.
The ophthalmoscope is used to examine the eye’s interior surface, including the retina, optic disc, and the back of the eye, also known as the fundus. This device provides insightful real-time images that can help diagnose conditions like retinal detachment, glaucoma, and other disorders related to blood vessels.
The slit lamp, also known as a biomicroscope, is used to examine the front part of the eye, including the eyelids, cornea, iris, and lens. An optometrist uses this to diagnose cataracts, macular degeneration, conjunctivitis, and other eye conditions.
The tonometer tests the eye’s interior pressure, which is critical in diagnosing glaucoma. It usually involves a small puff of air on the surface of your eye while you stare directly at the machine.
A keratometer, or ophthalmometer, measures the cornea’s curvature. This tool is especially essential for sizing contact lenses.
The retinoscope is used to measure a person’s refractive error objectively. By examining the reflection of light off the retina, the doctor can have a good starting point for the eyeglass prescription.
The auto-refractor and autokeratometer evaluate how a patient’s eye processes light, providing essential data for a glasses or contact lens prescription. They also measure the curvature of your cornea, providing important details for fitting contact lenses.
