Healthy Eyes,
Clearer Vision
The definitive app for daily eye care. Test your visual acuity, check for astigmatism, track screen fatigue, and train your eye muscles — guided by Orby.
Everything You Need for Eye Health
Five powerful diagnostic tests and daily exercises in one beautiful app. Built to fight screen fatigue and keep your vision sharp.
Visual Acuity Test
Measure your near-vision sharpness right from your phone. Using standard tumbling E optotypes, Orby accurately estimates your Snellen visual acuity (e.g., 20/20).
Astigmatism & Distortion Checks
Quickly screen for visual distortions using classic high-contrast diagnostic dials and the Amsler Grid. Catch signs of eye strain or macular issues early.
Color & Contrast Tracking
Test for red-green color deficiencies with interactive Ishihara plates, and track your contrast sensitivity to know exactly when digital eye strain is setting in.
Daily Eye Workouts
Relieve tension with guided ocular exercises. Follow smooth animations to stretch your eye muscles, practice blink training, and relax with the 20-20-20 rule.
Track Your Progress
Build healthy habits with daily streaks. Review your historical test results to see how your contrast sensitivity and eye strain improve over time.
App Experience
Explore the calm, distraction-free interface designed for your eyes.
