Free · In‑App Purchases
SightFrame is an interactive vision simulator and eye-care educational tool. Using advanced real-time image processing, SightFrame allows you to see the world through the perspective of individuals with myopia, astigmatism, presbyopia, and color vision deficiencies. KEY FEATURES: 1. Real-Time Camera Simulation • Live Diopter Control: Adjust spherical power from 0 to -10.0D+ to observe realistic distance defocus. • Astigmatism Effects: Directional blur, streaks, and double-vision glare—especially in low-light environments. • Presbyopia Mode: Central focus difficulty simulating age-related near vision loss. • Color Deficiency Filters: Protanopia, Deuteranopia, and Tritanopia color matrix transformations. 2. Realistic Preset Scenes • Explore common everyday environments like night driving, classroom blackboards, metro signs, and rainy streetscapes. • Switch effortlessly between clear vision and simulated refractive errors. 3. Split-Screen Comparison & Fine Tuning • Compare side-by-side (Split View) between normal vision and simulated filters. • Fine-tune blur radius, halo intensity, pupil distance, and astigmatism axis angles. 4. Standard Eye Chart • Interactive Tumbling E / Snellen chart for eye test exploration and vision awareness. 5. Privacy & Clean Experience • 100% On-Device Processing: Camera feed is rendered locally in real time. We NEVER record, save, or upload your photos or videos. • No Ads: Enjoy an uninterrupted, seamless visual journey. DISCLAIMER: SightFrame is intended for educational, empathy, and simulation purposes only. It does not provide medical diagnoses or replace professional eye examinations. For any vision concerns, please consult a certified optometrist or ophthalmologist.
