Visual Acuity Charts, Projectors & Digital Systems
Visual acuity testing is the backbone of every refraction lane, and the device you choose sets the pace and precision of the whole exam. This category brings together the three ways modern practices present optotypes: LCD digital acuity charts that render a full test library on a crisp flat panel, chart projectors that cast optotypes onto a reflective screen, and remote-controlled chart panels for compact or secondary lanes. Beyond the classic letter, number, and pediatric charts, most current systems add binocular balance, aniseikonia, phoria, stereopsis, contrast sensitivity, and color-vision tests, plus a randomize function so patients cannot memorize the sequence.
As a US-based ophthalmic and optometric equipment provider, we help you match the right visual acuity system to your room size, refractor setup, and budget rather than simply shipping a box. Our own Ezer line covers digital charts and projectors at a practical price point, and every unit we sell is backed by our in-house technical and repair department, US warranty, and spare-parts support, so a display or light-source issue years from now does not sideline a lane. New and factory-refurbished options are available across most models.
How to choose a visual acuity system
- Display technology: Decide between an LCD digital chart, a chart projector, and a chart panel. LCD charts give the sharpest optotypes, the largest test library, and silent instant chart changes; projectors are a proven, economical option many doctors still prefer; simple panels suit compact or screening lanes.
- Room size and testing distance: Confirm the throw distance your lane allows. Digital charts and projectors calibrate optotype size to the working distance, and most support a mirror mode so you can run a standard exam in a shorter room. Check the supported distance range before you commit.
- Test library and binocular capability: If you perform binocular balance, aniseikonia, phoria, stereo, or fusion testing, choose a system with polarization or red/green filters and those charts built in. Contrast sensitivity, color vision, and pediatric or illiterate optotypes are worth confirming, along with a randomize function to prevent memorization.
- Refractor integration and controls: A chart system that talks to your phoropter or digital refractor streamlines the subjective refraction. Look at remote-control ergonomics, programmable favorite charts, and compatibility with your existing autorefractor and phoropter brand.
- Light source and serviceability: For projectors, an LED light source lasts far longer than a conventional bulb and stays cooler and brighter. Whatever you choose, weigh long-term serviceability: parts availability, warranty, and access to a repair department that can keep the unit running.
- New vs. refurbished: Factory-refurbished charts and projectors can be a smart way to equip a second lane or a startup practice. Buy refurbished units that carry a genuine warranty and service support so you get the savings without the risk.

Frequently asked questions
What is the difference between an LCD digital acuity chart and a chart projector? An LCD digital chart displays optotypes on a flat-panel screen, giving very sharp, high-contrast letters, silent instant chart changes, and a large built-in test library. A chart projector casts optotypes onto a reflective screen and remains a proven, economical choice many practices prefer. Both measure visual acuity accurately; the decision usually comes down to image quality, test variety, room layout, and budget.
How much room do I need, and can I use these in a short exam lane? Most visual acuity systems calibrate optotype size to your working distance and support a mirror mode, which folds the light path so you can run a standard-distance exam in a physically shorter room. Check each model's supported distance range against your lane before ordering, and we can advise on mirror setups.
Can these systems integrate with my phoropter or autorefractor? Many digital charts and projectors connect with digital refractor systems and offer remote control with programmable favorite charts to speed subjective refraction. Compatibility depends on the brands involved, so tell us your current phoropter and autorefractor and we will confirm what works together.
Is an LED chart projector better than a bulb model? An LED light source lasts far longer than a traditional projector bulb, runs cooler, and typically delivers brighter, clearer optotypes with little maintenance. If you prefer projection over a digital display, an LED model such as the HCP-7000 C-LED reduces lamp replacements and downtime over the life of the unit.
Do you offer refurbished units, warranty, and service? Yes. We carry new and factory-refurbished visual acuity systems, back them with a US warranty, and support them through our in-house technical and repair department with spare-parts availability. That means a chart, display, or light-source issue can be serviced rather than forcing a full replacement.
