1: What’s the difference between the A05 and the A03?

A: Both models share the same core function – lenses fog up automatically when distance or posture is incorrect. The main difference is the wearing style: the A03 is a standalone frame worn directly, while the A05 is a clipon design that can be attached to a child’s existing prescription glasses. The A05 is ideal for children who already wear glasses.

2: Can the A05 fit on any pair of glasses?

A: The A05 features a universal clipon design that fits most common spectacle frames. The TR90 temples are flexible and durable, providing a secure, nonslip fit.

3: How accurate is the monitoring on the A05?

A: The A05 uses a laser ranging sensor + 3axis gyroscope dualsensor system. Compared to the A03’s 6axis gyroscope + distance sensor, the laserbased distance measurement responds faster and with higher precision, triggering the fogging reminder more promptly.

4: How long does the battery last?

A: The A05 has a builtin 40mAh lithiumpolymer battery, providing about 20 hours of use and 160 hours of standby on a full charge. It supports magnetic charging and takes about 1.5 hours to fully charge. It powers on automatically when clipped on and powers off when removed, which helps conserve battery.

5: Does the lens transparency affect vision? Can the child see clearly through them?

A: The electronic fogging lenses on the A05 have a light transmittance of over 90% when clear, so they do not interfere with normal reading or writing. They only fog up when posture is incorrect, acting as a visual reminder, and clear up immediately once the correct posture is restored.

6: Is it suitable for children who already wear prescription glasses?

A: Yes, absolutely. The A05 is specifically designed as a visionprotection aid for children who already wear glasses. Simply clip it onto their existing frames – no additional prescription needed.
