SightFrame: Vision Simulator

Real-time Eye & Vision Filter

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 -8.0D 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. Vision Self-Checks • Explore Visual Clarity, Astigmatism Dial, Red-Green Balance, and Amsler Grid checks. • Save results for personal reference and review changes over time. • Self-checks are informational only and do not provide diagnosis or prescription. 5. Visual Breaks & Tracking • Practice Gabor visual discrimination, guided 20-20-20 screen breaks, and gentle figure-8 visual tracking. • Track completed sessions, streaks, and personal best scores. • Stop immediately if you experience eye strain or discomfort. 6. Family Vision Profiles • Create separate profiles for family members and organize prescription details and self-check history. • Review visual-acuity trends and previous records in one place. • Protect local health records with optional Face ID, Touch ID, or device passcode. 7. 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. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
