Smart vision care, anytime
Are your eyes feeling tired after hours of screen time? uSagI Eyes Protect helps you protect and monitor your vision with smart, science-backed tools — detect issues early and build healthy eye-care habits, easily and effectively.
Digital screens are straining your eyes
Eye Fatigue
Extended screen use causes digital eye strain — sore, tired eyes after just a few hours.
Blurred Vision
Hours of close-up focus blur your vision and reduce your ability to shift between distances.
Silent Decline
Vision changes often go unnoticed until they become significant — early detection matters.
Science-backed eye care tools
Internationally recognized tests and smart reminders, built into a simple app you'll actually use.
C-Chart Visual Acuity Test
Measure how clearly you see at both near (30 cm) and far (300 cm) distances using the internationally recognized Landolt C-chart — the same method used by professionals to assess visual sharpness.
→ Track vision changes over time and compare results
Ishihara Color Blindness Test
Quickly check for color vision deficiencies — such as red-green color blindness — using the Ishihara Test, a globally trusted method presenting number patterns hidden in colored dot plates.
→ Detect inherited or acquired deficiencies early
Smart Eye Care Reminders
Set personalized break reminders to rest your eyes at regular intervals, following the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
→ Reduce eye fatigue and maintain long-term comfort
