Usage

For optimal results, use the FY-1 Butterfly Flipper Rack under the guidance of a professional. Continue training even after your symptoms improve to maintain and enhance your visual skills.

Train with different degree lenses ranging from ±1.00 to ±2.00, starting with ±1.00. Use the rock card 20/40 at a distance of 40cm and track your progress as you switch between positive and negative lenses. Both monocular and binocular training are essential for clear vision at every switch.

Normal Steps

1. Place a vision testing card at a 40cm distance, using 20/30, 20/40, or 20/50.

2. Start with ±1.00 lenses, ensuring clear vision with +1.00 first.

3. Quickly switch to -1.00 lenses, maintaining clear vision.

4. Progress from single-letter to five-letter training on the Rock Card.

5. Repeatedly switch lenses, reading letters aloud as quickly as possible while ensuring clear vision.

6. Train 1-2 times daily for 10-15 minutes per session.

7. Aim for a normal response time of at least 3 seconds per cycle, achieving 20 cycles per minute with less than a 2-cycle difference between eyes.

8. Complete a 15-day training course to see significant symptom improvement.

Tips

1. After mastering ±1.00, proceed to ±1.50, following the same method.

2. Continue to ±2.00, training until you reach the normal response time of 3 seconds per cycle.

3. Keep in touch with your optometrist for guidance and support throughout your training journey.
