Designed for children aged 8–14, these glasses are lightweight, comfortable, and effortless to wear. The core feature is the photochromic lenses, which automatically adjust according to UV intensity, providing all-day UV400 protection to safeguard delicate young eyes. High-toughness lenses paired with a TR90 frame ensure stability and comfort, while side air vents effectively expel heat and moisture, reducing stuffiness for long-term wear.
| Light Condition | Lens State | Description |

| Night / Indoor | Transparent | Ideal for low-light conditions or indoor wear |
| Cloudy Day | Light | Perfect for overcast or evening rides |
| Direct Sunlight | Dark | Provides maximum protection in bright sunlight |
Designed to fit the natural curve of a child’s face for a secure and comfortable fit.
