Visual Acuity Charts & Systems

Visual Acuity Charts and Digital Acuity Systems

Visual acuity testing sets the pace of every refraction lane. Practices present optotypes in three main ways: LCD digital acuity charts that show a full test library on a screen, chart projectors that project optotypes onto a screen across the room, and chart panels for compact rooms, near testing and secondary lanes.

This page brings together the acuity equipment US Ophthalmic offers in the US: Ezer and Luxvision LCD acuity charts, the Gilras GDC-7000 acuity tester, Ezer and Luxvision chart projectors, Luxvision vision chart panels, and the stands and accessories that go with them. US Ophthalmic is a US provider of ophthalmic equipment; we manufacture the Ezer line and back it with an in-house technical department and spare-parts stock. Tell us your lane length and setup and we will recommend a configuration with a quote.

How to choose a visual acuity system

• Lane length: Measure the distance from the patient's eye to the chart. Digital charts can be calibrated for shorter lanes and mirror setups can lengthen the path; projectors need a set distance to the screen.
• Digital chart or projector: An LCD chart offers a larger test library, randomized optotypes and easy calibration; a projector is familiar and simple to run.
• Test library: Check the optotypes (letters, numbers, Tumbling E, Landolt C, pictures) and the binocular, color and contrast tests you need.
• Phoropter link: If you use a digital phoropter, confirm the chart can be controlled from the same console so the chart changes with the test.
• Mounting: Decide between wall mount, stand or arm mounting, and check the screen size against your lane length.
• Service and parts: Ask who services the instrument in the US, how consumables and spare parts are supplied, and what the US warranty covers.

Frequently asked questions

What distance should a visual acuity chart be from the patient? Distance acuity is defined at 20 feet (6 meters). Shorter rooms use a chart calibrated for the actual distance or a mirror to lengthen the path.

Should I choose an LCD acuity chart or a chart projector? LCD charts offer more tests and randomized optotypes and are easy to calibrate for short lanes; projectors are simple and familiar. Either can be paired with a phoropter.

Do you sell refurbished acuity charts? No. US Ophthalmic sells new equipment only. For a lower budget, contact us about open-box availability; open-box units are inspected and function-checked.
