1. Product Form: From “Clip-On Accessory” to “Standalone Glasses”

The A05 children’s corrective glasses use a clip-on design that can be attached to ordinary glasses. This design mainly targets children who already wear prescription glasses, avoiding the trouble of re-fitting lenses and reducing switching costs. Laser ranging and a 3-axis gyroscope handle distance monitoring and head posture monitoring respectively, and the core logic remains “behavioral reminders.”

The A07 is a standalone, complete pair of smart glasses that does not need to be attached to any base glasses. The whole unit weighs about 35g and uses TR90/PC materials. Simply wear it and automatic monitoring begins. This change in form brings two direct advantages:

1. Wider user coverage
   Children who do not wear glasses can also use it, without the need to add a base frame just for posture correction.

2. Better wearing consistency
   The standalone structure avoids position shifting between the clip-on module and the base glasses, making sensor data collection more stable and alerts more accurate.

From a product definition perspective, the A05 is “adding a smart external module for children who already wear glasses,” while the A07 is “providing a complete pair of smart vision protection glasses for all children.” The latter clearly has stronger market universality.

2. Functional Dimensions: From “Distance + Angle” to “Distance + Angle + Bright Light”

The A05’s core monitoring functions focus on two aspects: laser ranging for reading distance and a 3-axis gyroscope for head tilt angle. These already cover the two most important near-work behavioral indicators in myopia prevention.

The A07 adds a key function on this basis — bright light detection, which records the time children spend in outdoor bright light environments. This addition is not simple parameter stacking, but corresponds to an important consensus in the field of myopia prevention: sufficient daily outdoor activity time is an effective way to slow axial eye growth and reduce the incidence of myopia.

Therefore, the A07’s functional structure expands from “passively correcting poor eye-use behavior” to “correcting behavior + recording healthy habits.” It not only reminds children “what not to do,” but also helps parents understand whether the child is “doing the right thing.” This upgrade from single reminders to behavioral data recording is an important generational feature that distinguishes the A07 from the A05.

3. Alert Method and Usage Threshold: Non-Intrusive Intervention and Zero Learning Cost

The A05’s specific alert method is not emphasized in available materials, but based on its clip-on structure and sensor solution, it typically uses vibration or sound. The A07 clearly uses a motor vibration alert, which is more advantageous in environments that require quiet, such as classrooms and self-study sessions.

More importantly, the A07 emphasizes “no smartphone, no app, just power on and use.” After pressing the physical power button, the glasses automatically enter fully automatic monitoring mode, and all algorithms run locally. For children’s products, this zero learning cost design is crucial — children do not need to understand any settings, and parents do not need to worry about misoperation or device connection issues.

The A05 is also positioned for lightweight use, but the clip-on structure means users must first ensure the base glasses fit properly before adding the smart module, adding one more step compared to the A07. For younger children or children who have not yet worn glasses, the A07’s standalone form is friendlier.

4. Battery Life and Charging: From “Sufficient” to “Barely Noticeable”

The A05’s specific battery data is not clearly given in available materials, but the A07 provides complete parameters: a 110mAh lithium-polymer battery, approximately 200 hours of standby time, and a full charge in about 1.5 hours. A 200-hour standby means that even with several hours of daily wear, the device can run for weeks without frequent charging. The magnetic charging design further lowers the usage threshold for children — simply place the glasses on the charger.

This long battery life is especially important for children’s products. Children often lack the awareness to actively charge devices, and if the device frequently runs out of power, it is easily abandoned. The A07 improves actual usage through the combination of “low-power sensors + long standby + convenient charging.”

5. Price and Market Positioning

The A05 is priced at 599 RMB per unit, offering reasonable cost performance among clip-on children’s smart glasses. The A07’s price has not been officially announced, but given its standalone frame, three-in-one sensor solution, and wider market coverage, it is expected to become the main sales model in SPAEXI’s children’s vision protection series if priced reasonably.

It should be noted that the A05’s clip-on solution still holds value for specific groups — especially children who already wear prescription glasses and do not want to change frames. Therefore, the A05 and A07 form a complementary relationship of “external attachment + standalone” in SPAEXI’s product matrix, rather than a simple upper-lower substitution.

6. Industry Perspective: Children’s Smart Glasses Are Moving from “Functional Add-On” to “Standalone Category”

The evolution from A05 to A07 reflects an important trend in the children’s vision protection track: smart correction functions are developing from “modules attached to ordinary glasses” into “standalone complete smart wearable devices.” The standalone form not only improves wearing stability and data accuracy, but also provides space for integrating more health monitoring functions in the future.

Through self-developed and self-manufactured products and OEM/ODM capabilities, SPAEXI can flexibly adjust between A05 and A07, meeting both the lightweight external needs of children who already wear glasses and providing standalone smart solutions for a broader group of children. This dual-track layout gives SPAEXI stronger channel adaptability and product extensibility in the children’s myopia prevention market.
