Vision Charts
A vision chart is the reference standard at the heart of every eye exam, presenting rows of optotypes that let an optometrist or ophthalmologist quantify a patient's visual acuity. Modern digital vision charts have largely replaced printed wall charts and bulb-based projectors: an LED-backlit LCD panel delivers standardized, uniform illumination across the entire surface, changes test lines electronically, and holds its calibration far more consistently than paper or a fading lamp. The result is faster, more repeatable acuity measurement in the lane, the pretest room, and the dispensary.
US Ophthalmic is a US-based ophthalmic and optometric equipment provider, not a drop-ship reseller. This collection carries the Luxvision CP-series of digital vision charts spanning full-distance, compact-distance, remote-controlled, and near-vision models, and every unit is backed by our US warranty, our in-house technical and repair department, and stocked spare parts. Alongside carried brands, we also build and service equipment under our own EZER house brand, so the same team that sells you a chart can keep it running.

How to choose a vision chart
- Working distance and room size: Start with the length of your exam lane. The CP-5000 is designed for a full 5-meter (roughly 16.4-foot) working distance, while the CP-4000 is calibrated for a shorter 3-meter (10-foot) lane and fits compact rooms and pretest areas. Choosing the chart that matches your actual distance keeps acuity readings valid.
- Distance versus near testing: Decide whether you need distance acuity, near acuity, or both. Distance charts like the CP-5000, CP-4000, and the remote-controlled CP-1000 handle across-the-room testing, while the CP-3000 and CP-3003 are dedicated near charts for reading and close-work assessment at about 16 inches. Most lanes are best equipped with one of each.
- Consistent LED illumination: Reliable acuity depends on even, standardized light on every optotype. The CP-series uses LED backlight technology that delivers uniform luminance across the whole testing surface, avoiding the brightness drift of an aging projector bulb or a sun-faded printed chart.
- Control and clinical workflow: Think about how staff will drive the chart during an exam. The CP-1000 adds remote control for quick, chair-side line changes, and near models ship with a pointer for guiding the patient. Table-or-wall mounting on most models lets you place the chart where the workflow is smoothest.
- Service, warranty, and spare parts: A vision chart is a long-lived lane fixture, so buy from a provider that can support it. Every unit we carry is backed by a US warranty, our in-house repair department, and stocked spare parts, so the device stays serviceable for years rather than becoming disposable.

| Model | Type | Best for |
|---|---|---|
| CP-5000 | Distance LCD chart, up to 5 m (16.4 ft) | Standard exam lanes with a full working distance |
| CP-4000 | Compact distance LCD chart, 3 m (10 ft) | Shorter lanes, pretest areas, and space-limited rooms |
| CP-1000 | Distance chart panel with remote control | Lanes that want simple, chair-side remote operation |
| CP-3003 | Near visual acuity chart, LED-backlit | Near and reading acuity at the desk or chair side |

Frequently asked questions
What is the difference between a distance and a near vision chart? A distance vision chart measures acuity across the exam lane, where the patient reads progressively smaller optotypes from several feet away. In this lineup, the CP-5000 and CP-4000 are distance charts, and the CP-1000 is a remote-controlled distance panel. A near vision chart evaluates reading and close-work acuity at roughly 16 inches, which is the job of the CP-3000 and CP-3003. Many practices run both a distance and a near chart so a single exam covers the full working range.
Which model fits my exam lane length? Match the chart to your lane's working distance. The CP-5000 is built for a full 5-meter (about 16.4-foot) lane, while the CP-4000 is calibrated for a shorter 3-meter (10-foot) distance and suits compact rooms and pretest areas. If your lane is short and you rely on a mirror to fold the optical path, confirm the effective distance with our team before ordering so the chart and room geometry line up.
Why choose a digital LCD vision chart over a printed wall chart or an older projector? Digital charts use LED backlighting for standardized, uniform illumination across the whole surface, which supports repeatable acuity readings that a fading printed chart or an aging projector bulb cannot guarantee. Digital panels also let you change optotype lines and test sets electronically instead of swapping physical cards, and models like the CP-1000 add remote control to keep the workflow at the chair moving quickly.
Can I mount these charts on a wall or use them on a tabletop? Yes. The CP-5000, CP-4000, CP-3000, and CP-3003 can all be placed on a table or hung on a wall, so you can fit them to the room rather than the other way around. Near charts such as the CP-3000 also offer flexible power (AAA, USB, or AC adapter), which makes them easy to position at the desk or chair side.
Do vision charts from US Ophthalmic come with warranty and service support? Yes. As a US-based provider, we back the vision charts we carry with a US warranty and our in-house technical and repair department, and we stock spare parts so a device can be supported over its full service life rather than replaced at the first fault. If you are weighing new versus refurbished, ask us for current availability and the warranty terms on each option before you request a quote.
