For optometrists and eye care practices

Give patients a practical screen-comfort routine they can use at home.

Patients reporting eye fatigue, dryness, and trouble focusing on screens often need help turning general advice into daily habits. CircadianShield supports display-setting education, 20-20-20 break reminders, and a printable home-use summary they can bring to their next visit.

A take-home support tool, not a take-home lecture.

Patients install in under a minute. The app supports display-comfort habits in the background. They print a one-page summary before their next visit so you have screen-environment context to discuss.

The visit-to-visit protocol
  1. Patient presents with screen-related concerns such as dryness, focus fatigue, or late-evening screen use.
  2. You hand them a card with the install URL and your bulk license code. Setup is two clicks: a wake/sleep time and a permission grant.
  3. For 30 days the app runs silently, tracking screen time, break follow-through, evening melanopic load estimates, and morning daylight context.
  4. Before their next appointment they hit "Print Eye Health Report" inside the app and bring the one-page PDF.
  5. You review four numbers (7-day score, breaks followed, average screen time, light debt) as patient-reported context alongside your clinical judgment.

A real tool, grounded in the evidence you already cite.

Solar-aligned filtering

The screen warms automatically through the day, holding daytime crispness and shifting to red-shifted evening tones. Not a clock-based timer, not a manual toggle.

Melanopic EDI targeting

The app estimates melanopic EDI so patients can understand evening screen light in context. It is an education metric, not a diagnostic measurement.

20-20-20 break enforcement

The 20-20-20 habit built in, with follow-through tracked. Multiple break-screen styles help patients keep the routine visible without relying on memory.

Morning Boost protocol

For the first ~2 hours after sunrise the screen runs at full daytime color temperature to support a clear distinction between daytime and evening display settings.

PWM Protection (Pro)

Software dimming overlay for patients sensitive to backlight pulse-width modulation, especially on OLED panels and certain laptop displays.

Per-app rules (Pro)

Auto-disables for color-critical work (Photoshop, Lightroom). Cinema mode for video. So the patient never has a reason to turn it off entirely.

Every visit gets the same artifact.

The patient prints (or saves as PDF) a one-page summary directly from the app. Same layout every time. Easy to scan during a 15-minute visit, easy to compare to last month.

Top: 4 KPIs

7-day score, breaks taken, average screen time, average light debt. Each with a directional indicator.

Middle: Daily score chart

Bar chart of the past 7 days. Spots a single bad-night-everything-collapses pattern instantly.

Bottom: Evidence callouts

One-line explanations of light debt, melanopic EDI, and 20-20-20, so the patient can read the report without you.

Simple, per-code pricing.

You buy a block of license codes, you give them to patients. They activate on their personal Mac or PC. No per-machine cap surprises, no clinic-network deployment.

Patient education and clinical references.

These pages are written for clinic staff, patient handouts, and take-home reading. Share them directly with patients or use them as a reference for display-habit conversations.
