Refractors & Digital Phoropters
A refractor, also called a phoropter, is the cornerstone instrument of the exam lane. It presents a precise sequence of trial lenses so the doctor can perform subjective refraction, dialing in sphere, cylinder, axis, and add power to reach a patient's best-corrected vision. For ophthalmologists, optometrists, and lab owners, the refractor is where objective autorefractor data becomes a finished, prescribable Rx, so its optics, speed, and workflow shape the productivity of the entire lane. This collection spans both classic manual phoropters and modern digital (automated) refractor heads that motorize lens changes, guide the exam on a touchscreen, and share data across the pretest room.
US Ophthalmic is a US-based ophthalmic and optometric equipment provider, not a reseller. We build and back the Ezer line of refractors, carry trusted brands such as Huvitz, and stand behind every unit with an in-house technical and repair department, genuine spare parts, and a US warranty. Whether you are replacing an aging phoropter, outfitting a new exam lane, or standardizing a multi-lane practice on one platform, our team helps you match the right refractor to your patient volume, your connectivity needs, and your budget, then keeps it running long after the sale.
How to choose a refractor
- Digital vs. manual: Digital (automated) refractors motorize the lens changes and run the exam from a touchscreen, which speeds refractions and removes the tactile lag of a manual head. Manual phoropters remain a proven, lower-cost choice for new practices, backup lanes, or doctors who prefer hands-on refraction. Decide based on patient volume and how much you want to automate.
- Connectivity and data flow: A modern refractor should talk to the rest of your lane. Look for the ability to import measurements from your autorefractor and lensmeter and to push the final Rx onward, via Wi-Fi, LAN, USB, or RS-232, so staff are not retyping numbers. Bidirectional data transfer reduces transcription errors and shortens each visit.
- Testing capabilities and charts: Confirm the exam features you actually run day to day: single and dual cross-cylinder for astigmatism, binocular balance, near-vision testing, and a full library of distance and near charts (letters, numbers, tumbling E, pediatric, and astigmatic targets). Programmable exam sequences let each doctor standardize their preferred routine.
- Lane space and ergonomics: Slim, compact refractor heads reduce the tunnel-vision effect some patients feel with deeper optical bodies and free up lane space. Features like body tilt for natural near-vision posture and monocular height adjustment improve patient comfort and measurement accuracy, which matters most in high-volume or multi-doctor lanes.
- New vs. refurbished: Phoropters are durable, long-lived instruments, so a certified pre-owned or refurbished unit can be a smart way to equip a lane or add a backup at lower cost. Ask what was serviced and calibrated, and confirm the warranty. New units bring the latest digital workflows and full-term coverage.
- Service, parts, and support: A refractor is a multi-year investment, so who stands behind it is as important as the spec sheet. Our in-house repair team, genuine spare parts inventory, and US warranty mean calibration, service, and support come from the same provider that sold you the instrument, minimizing downtime in your lane.

Frequently asked questions
What is the difference between a refractor and a phoropter? They refer to the same instrument. Refractor and phoropter both describe the device that holds a rotating set of trial lenses used for subjective refraction. Digital or automated refractors add motorized lens changes and touchscreen control, while manual phoropters are adjusted by hand.
Should I choose a digital or a manual refractor? It depends on volume and workflow. Digital refractors speed exams, cut transcription errors, and connect to your autorefractor, lensmeter, and EMR, which pays off in busy or multi-doctor lanes. Manual phoropters cost less up front and are a solid choice for new practices, backup lanes, or doctors who prefer a hands-on refraction. Our team can help you weigh the trade-offs for your practice.
Do these refractors connect to autorefractors, lensmeters, and EMR systems? The digital models are built to share data. Depending on the model, they support Wi-Fi, LAN, USB, or serial connections so measurements flow in from pretest devices and the final prescription moves onward without manual re-entry. Ask us to confirm the exact connectivity and integration options for the model you are considering.
Can I buy a refurbished refractor, and is it a good option? Yes. Because phoropters hold their accuracy and value for many years, a properly serviced and calibrated refurbished unit is a cost-effective way to equip a lane or add a backup. We can advise on availability, what was serviced, and the warranty that applies.
What service and warranty come with a refractor from US Ophthalmic? As a provider rather than a reseller, we back our refractors with a US warranty and an in-house technical and repair department that stocks genuine spare parts. That means calibration, service, and support come directly from us, keeping your exam lane running with minimal downtime.
