Product description
- The Confirmation Flipper ±1.50 D is a near-vision lens flipper that builds and checks accommodative facility—your ability to shift focus quickly and accurately at near. With equal +1.50 / −1.50 lenses mounted back-to-back, it’s ideal for timed reading tasks to confirm performance, reduce symptoms like near blur/strain, and track improvement across visits (clinic or supervised home use).
- What it trains/tests: Speed and accuracy of focus changes (accommodation); can also be used for binocular facility when paired with suppression checks
- How to use (quick start): Sit at ~40 cm with a near target (e.g., words/letters) → view through +1.50, clear the target → flip to −1.50, clear again → continue for a timed trial and record cycles per minute (CPM)
- Why ±1.50 D: A moderate, widely used step that challenges focusing without overwhelming beginners—good for baseline and progression
- Best practices: Keep target size/lighting consistent, encourage clear & single before flipping, log CPM + symptoms (effort, blur, headache)
- Who it’s for: Pediatrics to adults—optometry/orthoptics clinics, and home programs under clinician guidance
- Combine with: Hart chart or reading strips for standardized text; RG bar reader or Brock string if doing binocular facility blocks
- Build & care: Lightweight handle for rapid, repeatable flips; clean lenses with lens-safe solution, store in a protective pouch to prevent scratches
| Topic | Details |
| Catagory | Vision Therapy Tool |
| Material | The flipper frame is typically made from durable plastic with an ergonomic handle, designed for comfortable use during repeated therapy sessions. The lenses are made from optical-grade glass, providing clear vision with minimal distortion and long-term optical stability. |
| Item Weight | Approximately 50 grams, making it lightweight and easy to handle during extended clinical or therapy sessions. |
| Flipper Dimensions | Approximate overall size: 20.5 × 9.5 cm (8 × 3.5 inches), designed to allow easy flipping between lenses during testing or therapy. |
| How to use for | The flipper contains +1.50 D and −1.50 D spherical lenses mounted on opposite sides. The patient views a near target while the examiner or patient flips the lenses alternately. This action requires the eyes to rapidly adjust focus (accommodate and relax accommodation), improving accommodative flexibility. |
| Purpose | The ±1.50 Confirmation Flipper is used to assess and train accommodative facility, which is the ability of the eyes to quickly change focus between different lens powers. It is commonly used to evaluate accommodative responses and confirm appropriate focusing ability during vision therapy or clinical assessment. |
| Lens Diameter | Lens diameter is typically approximately 37 mm, allowing a comfortable field of view during near vision therapy exercises. |
| Durability | Designed for frequent clinical use, the flipper features durable optical lenses and a sturdy handle. Glass lenses resist yellowing and maintain optical clarity over time. The frame construction ensures reliable performance during repeated flipping motions in therapy sessions. |
| Unique Selling Proposition (USP) | Provides immediate visual feedback during accommodative facility testing and training. High-quality optical lenses ensure accurate focus changes without distortion. Clearly marked lens powers help clinicians and patients easily identify the correct lens orientation during therapy. |
| Additional Benefits | The flipper is lightweight, portable, and easy to clean, making it suitable for both clinic-based and home-based vision therapy exercises. Clear labeling and durable construction make it a reliable tool for long-term therapy use. |
