It's covered.

Optotypes are rendered as vector geometric paths — not fonts. That eliminates font substitution and anti-aliasing inconsistencies and keeps letterforms identical on every device and platform. Combined with physical ruler-based calibration, sizing is clinically validated rather than assumed from the screen’s reported specs.

Optometrists, ophthalmologists, and ophthalmic technicians in private practice, group practices, and academic settings. It’s built specifically for eye care professionals who need clinical-grade acuity testing on digital displays.

Ocular Edge runs as a Progressive Web App in any modern browser, plus native apps for Android (Google Play), Amazon Fire TV, and Samsung TV (Tizen). If a screen can run a browser and be calibrated, it can be an exam lane.

Yes. Once loaded, the app is fully offline-capable via service-worker caching. Exam charts, calibration, and scoring all work without an internet connection — only admin features and real-time sync require connectivity. A dropped connection never interrupts a patient exam.

During setup, you physically measure a ruler or credit card against an on-screen overlay. That gives the exact pixels-per-millimeter ratio for your specific screen. Browser-reported DPI is never trusted — your physical measurement is the single source of truth.

The sizing formula is validated by a suite of 41 clinical accuracy tests. At 20 feet, a 20/20 letter measures 8.87 mm and a 20/200 letter measures 88.7 mm, and adjacent LogMAR lines maintain the correct 1.2589× size ratio — verifiable against a physical ruler on your own screen.

No. Calibration profiles are stored locally on each device. You only need to recalibrate if you change the screen, resolution, or zoom level — and the system warns you if it detects any of those changes.

Yes. Line spacing, inter-letter spacing, and per-letter LogMAR scoring follow ETDRS (Early Treatment Diabetic Retinopathy Study) standards: five letters per line, 0.1 logMAR steps between lines, and −0.02 logMAR credited per correct letter.

Yes. The calibration wizard works on any touchscreen device — hold a credit card or ruler against the screen and drag the overlay to match. The same pixels-per-millimeter accuracy applies regardless of screen size.

Yes, and it’s part of setup: you tell each lane its testing distance and every optotype is sized for that exact distance using the clinical MAR formula. Standard 20-foot lanes, mirrored lanes, and shorter rooms are all supported.

All 20, in every plan: Sloan Letters, Number Charts, LogMAR/ETDRS, Tumbling E, Landolt C, HOTV, Kids Animals, Inverse B&W, Color Vision (R/G), Astigmatism Dial, Duochrome, Contrast Sensitivity, Fixation Dot, Worth 4 Dot, Amsler Grid, Cross Cylinder, Coincidence, G/R Balance, Schober, and Traffic Lights. Every acuity chart uses the same clinically accurate sizing formula.

Yes. The LogMAR/ETDRS chart follows the Early Treatment Diabetic Retinopathy Study standard: 5 letters per line, 0.1 logMAR steps, and per-letter −0.02 logMAR scoring. Sizing and spacing match the ETDRS protocol used in clinical research and trials.

Snellen acuity is a fraction (e.g., 20/40) — the ratio of test distance to the distance at which a letter subtends 5 arc minutes. LogMAR (Log of the Minimum Angle of Resolution) is the logarithmic equivalent used in research for more precise, statistically valid scoring: 20/20 = 0.0 logMAR, 20/40 = 0.3 logMAR. Ocular Edge can display both formats.

Yes. Single-optotype presentation isolates individual letters, eliminating the crowding effect that can mask the true acuity of an amblyopic eye. HOTV and Tumbling E modes are also ideal for non-verbal amblyopia screening in children.

Yes. HOTV uses the matching-card method (no letter knowledge required), Kids Animals uses friendly illustrations that hold young children’s attention, and Tumbling E is language-free direction matching. All pediatric modes are calibrated to the same clinical sizing standards as adult charts.

Beyond acuity: Worth 4 Dot, Schober, G/R Balance, Coincidence, and Traffic Lights for binocular vision and red/green balance testing, plus the Astigmatism Dial, Duochrome for refraction refinement, Contrast Sensitivity, and the Amsler Grid for central-field screening.

TRIAD is Ocular Edge’s adaptive vision screening: 45 trials driven by three QUEST+ adaptive channels measuring acuity, contrast sensitivity, and crowded acuity. It produces a channel-by-channel profile with a plain-language narrative and suggested follow-ups. See the TRIAD page for the full science.

Describe a deck in a sentence — a welcome presentation, a blue-light lens promotion, a back-to-school campaign — and it generates branded slides in your practice colors with your logo. Twelve slide layouts and four visual themes, editable afterward, playing in your exam lanes and waiting room.

A self-running TV channel for your waiting room: your slide decks in rotation with your best patient reviews and curated eye-health tips, plus an optional live local weather sidebar with a 7-day forecast, a news ticker, a live clock, and your practice info bar. It runs in any TV browser with no extra hardware.

Three finished pieces per brief: a Facebook post, an email newsletter with a subject line, and a Google Business update — each written to its platform’s conventions in your choice of professional, friendly, or promotional tone, with optional clinic photos for authentic references.

Type or paste an encounter summary — or start from one of six templates — and it suggests ICD-10 diagnosis codes, CPT procedure codes, and modifiers, each with its clinical rationale and compliance notes. Suggestions are decision support: final coding always remains with the provider.

Claude, by Anthropic. Each tool is prompted with eye-care-specific context — your practice name, branding, the current month for seasonal content, and optometric coding conventions — so output is specific to your clinic, not generic filler.

Install the app from your TV’s app store (Amazon Fire TV or Samsung TV) or open the web app in the TV browser, then enter the 6-digit activation code from your admin dashboard to pair the TV to an exam lane. Calibrate once with a ruler and you’re testing.

No. Ocular Edge runs on any Smart TV, monitor, tablet, or computer with a web browser — the screens you already own. There’s no signage box, no media player, and nothing proprietary to buy.

Yes. A FLIRC USB adapter translates any IR remote’s buttons into keyboard events: number keys 1–9 launch chart types directly and arrow keys navigate lines and options during exams — hands-free chart control from across the room.

Yes. Add as many lanes as your plan covers — each lane pairs to its own screen, keeps its own calibration profile and testing distance, and switches independently between exam, waiting room, and idle modes.

Chrome, Edge, Safari, and Firefox on desktop and mobile. The app is a Progressive Web App (PWA) and can be installed to the home screen on any device for a native-like, full-screen experience.

No patient data is stored in the cloud. Calibration profiles live locally on each device, and exam results are displayed on screen for you to record in your EHR — Ocular Edge doesn’t retain them.

Yes! Every new account gets a 3-day free trial with access to all features — 3 exam lane seats, every chart type, and the AI tools. Exam lanes and the waiting room are unlimited during the trial; AI generations have small trial limits (2 slide decks, 3 billing queries, 3 social posts). No credit card required. After the trial, choose monthly lanes at $24.99/lane/month, a lifetime license at $449/lane (one-time), or the Enterprise plan at $225/month.

Every lane includes all 20 chart types and tests, full branding customization, offline capability, and FLIRC remote support. AI add-ons are separate account-wide subscriptions — or included automatically with Enterprise.

Two subscriptions: the Add-ons Bundle ($50/mo) covers the AI Slide Creator, Waiting Room Display, and Social Content Generator, and the AI Billing & Coding Companion is $80/mo. Both are account-wide — one subscription covers every lane and every staff member.

A one-time $449 payment per lane for permanent access to all chart types and branding features — no monthly lane fees, ever, with all future software updates included. It pays for itself in about 18 months versus monthly. AI add-ons remain separate monthly subscriptions.

Yes! Lifetime and monthly lanes work together on the same account — for example, two lifetime lanes in your main exam rooms plus a monthly lane at a satellite location. Each lane operates independently regardless of how it was purchased.

The Enterprise plan is the volume play: up to 20 lanes at $225/month flat — $11.25 per lane — with every add-on and AI Billing & Coding included, plus priority support.

Yes. All monthly plans are month-to-month with no contracts. Cancel from the Billing page in your dashboard and your access continues through the end of the billing period. Lifetime lanes never expire — they’re yours forever.
