Blink Deficit
33.3%
Dry-Eye Risk Score
85 / 100
Risk Level
High
High dry-eye risk indicated. Increase blink reminders, add screen breaks, and consider professional eye-care follow-up.
Planning tool only. Persistent eye symptoms should be reviewed by a qualified eye-care professional.
We can build and embed a custom version of Eye Blink Rate Dry Eye Risk Calculator for your brand and workflow.
Estimates risk impact from blink frequency compared with common resting blink expectations.
Models cumulative visual demand from prolonged daily screen-based activity.
Incorporates dry-air exposure and contact-lens usage effects to improve real-world risk interpretation.
At 10 blinks/min with 8 screen-hours, 35% humidity, and occasional lens use, the model indicates a moderate-to-high dryness risk profile.
Blink Deficit
~33.3%
Risk Score
~67 / 100
Risk Band
High
The model combines blink-rate deficit with digital visual load, humidity-related evaporation pressure, and contact-lens contribution to estimate a practical dry-eye risk score.
Inputs: Blink rate + screen hours + humidity + contact lens useOutput: Blink deficit + dry-eye risk score + risk levelUse Case: Visual comfort and workstation hygiene planningPair blink-rate analysis with lighting and glare calculators to build a more complete visual-comfort plan.
