Auto-Reversing Camera 200-Degree Children's Myopia and Amblyopia Vision Adjustment Trainer with Electric Reversal Function

This is a modern vision training tool specifically designed for children and seniors to improve myopia, amblyopia, and presbyopia while effectively training the eyes' accommodation and convergence abilities.

Core Functionality and Principle

*   Core Function: Automatically and uniformly switches between positive lenses (hyperopia lenses, relaxing the eyes) and negative lenses (myopia lenses, straining the eyes) in front of the eyes.
* Training Principle: Forces the eyes to rapidly and accurately shift focus between “distant viewing” and “near viewing” in response to lens changes. This exercises the flexibility and strength of the ciliary muscles, enhances ocular accommodation, slows myopia progression, and aids in treating accommodative amblyopia.

Key Features

1.  Motorized Automation:
    *   Parental Relief: Eliminates manual flipping, conserves energy, and ensures consistent, stable training rhythm.
    *   Scientific Pacing: Built-in fixed or adjustable time intervals (e.g., 3-5 seconds per cycle) guarantee scientifically sound and uniform training frequency, preventing issues of overly fast or slow manual operation.

2.  Professional Ophthalmic Grade:
    *   Designed based on professional training equipment used in ophthalmology hospitals and optometry centers, offering a portable home version that ensures training effectiveness and professionalism.

3. Precise Prescription (200D):
    *   Typically provides ±2.00D (equivalent to 200D) specifications, one of the most commonly used and effective training prescriptions, effectively stimulating the ciliary muscle to generate sufficient accommodation.

4.  Designed Specifically for Children:
    *   Lightweight and Comfortable: The lighter frame is suitable for children to wear, reducing the feeling of burden.
    *   Fun and Engaging: The motorized function itself is more appealing to children, helping them stick with long-term training.
    *   Safe and Durable: Typically made of safe plastic with rounded edges to prevent bumps and scrapes.

5.  Wide Applicability:
    *   Myopia Prevention & Control: An effective visual training tool for myopic children experiencing accommodation lag or eye strain.
    *   Amblyopia Treatment: Particularly suitable for amblyopic children with poor accommodation function as part of comprehensive therapy.
    *   Visual Training: Can be used to train binocular convergence and divergence functions, improving issues like convergence insufficiency.

Suitable Users

*   Children and adolescents requiring myopia prevention and control to slow progression.
*   Children diagnosed with accommodation dysfunction (e.g., poor accommodation flexibility, delayed accommodation).
*   Children with certain types of amblyopia requiring accommodation training as adjunctive therapy.
*   Individuals experiencing frequent visual fatigue, eye strain, or discomfort during prolonged screen use.

#### **Brief Usage Instructions (Always follow physician guidance)**

1.  **Preparation**: In a well-lit environment, wear corrective eyewear (if applicable). Position the vision chart 40 cm (16 inches) from the eyes.
2.  **Equipment Setup**: Put on the electric flip card device, ensuring both eyes are centered over the lenses.
3.  **Begin Training**: Turn on the switch. The device will automatically flip. The patient must clearly read the letters or E-chart symbols on the vision chart.
4.  **Training Requirements**: During lens switching (positive/negative), the target must maintain clarity as quickly as possible. Blurring, unrecognizable symbols, or double vision indicate insufficient accommodation ability. Reduce training difficulty or consult a doctor.
5.  **Training Duration**: Typically 1-2 sessions daily, with 5-10 minutes per session for each eye and both eyes combined. Follow specific instructions as prescribed by your doctor.

#### **Important Precautions**

*   **Must be used under professional guidance**: The Reverse Tap is a medical device. **Use requires prior examination and recommendation by an ophthalmologist or optometrist**. The doctor will determine suitability for the child and establish the specific training regimen (prescription strength, frequency, duration).
*   **Not a cure-all device**: This is a **training tool** that cannot “cure” myopia or amblyopia. It should be used as part of a comprehensive prevention and management system (e.g., sufficient outdoor activity, proper eye habits, optical correction).
*   **Consistency is key**: Visual training requires long-term persistence to see results.
*   **Regular Follow-ups**: Schedule periodic hospital visits during use to evaluate progress and adjust the program as needed.

**Summary**: This motorized auto-reversing pad leverages modern technology to make professional vision training accessible, convenient, and engaging at home. It serves as an effective tool for scientifically guided children's vision exercises. However, the fundamental principle remains: **Diagnosis comes first, training follows, and always adhere to medical advice**.
