Operating Instructions
AI Translation
The CuiSuto AI Translator Smart Glasses support real-time AI translation for over 100 languages. For full functionality, it is recommended to use the companion application (e.g., "Hyper MZT app" as mentioned in user reviews) on your smartphone. During video or audio calls, bilingual subtitles can automatically display, enhancing communication without requiring an app for web users.
Smart Color-Changing Lenses
The lenses feature slidable color-changing technology with UV400 protection, blocking 99% of harmful light. This allows for easy adaptation to various lighting conditions.
- To Darken Lenses: Gently slide your finger backward along the temple.
- To Brighten Lenses: Gently slide your finger forward along the temple.

Open-Ear Audio & HD Calls
Equipped with built-in air-conduction speakers and AI noise reduction, these glasses allow you to hear music and calls clearly while remaining aware of your surroundings. This eliminates the need for separate headphones.
