Modern lifestyles often mean extended exposure to digital screens, which can cause digital eye strain, blurred vision, and even unnoticed vision decline over time. uSagI helps you detect issues early and build healthy eye-care habits — easily and effectively.

Key Features
C-Chart Visual Acuity Test

Measure how clearly you see at both near (30cm) and far (300cm) distances using the internationally recognized Landolt C-chart. This test is commonly used by professionals to assess visual sharpness by identifying the direction of the "C" opening.
→ Track your vision changes over time and compare results to stay informed.

Ishihara Color Blindness Test

Quickly check for color vision deficiencies — such as red-green color blindness — using the Ishihara Test, a globally trusted method that presents number patterns hidden in colored dot plates.
→ Understand your color perception and detect inherited or acquired deficiencies early.

Smart Eye Care Reminders

Set personalized break reminders to rest your eyes at regular intervals, helping you follow the 20-20-20 rule (every 20 minutes, look at something 20 feet away for 20 seconds).
→ Reduce eye fatigue and maintain long-term visual comfort.

Built for Everyone
From professionals and students to gamers and casual users — uSagI Eyes Protect offers simple, yet powerful tools to care for your eyes proactively.
