Product description
- Quality, four-lens flipper bar featuring two alternating sets of red and green lenses.
- Ideal for use with non polarised Computerised Test Charts
| Topic | Discription |
| Purpose | The Red/Green Flipper is primarily used for anti-suppression training, binocular vision therapy (encouraging use of both eyes together), and sometimes accommodative/vergence facility when combined with red/green filters. For example, the website states: “A flipper with red/green lenses … used with vectographs and tranaglyphs to reverse BI/BO demands.” |
| Target users | Patients with binocular vision disorders such as amblyopia, suppression of one eye, strabismus, or children/adults undergoing vision-therapy targeting binocular function. Clinicians/orthoptists use them in therapy and home-training settings. They are less for pure acuity screening, more for binocular function, anti-suppression, dichoptic training. For example: red/green glasses (and by extension red/green flippers) are used to make each eye see different coloured stimuli so the brain must use them together. |
| Optotypes / Symbols | The flipper itself does not include optotypes or symbols. Instead, it is used with visual targets (charts, tranaglyphs, vectographs, reading materials) that are designed for red/green dichoptic training. In therapy you might pair the flipper with reading material having red/green bars, or charts with red/green symbols, or even overlapping red/green letters. The flipper’s job is to flip between red and green filters (or cause alternating red/green channel viewing) while the target remains constant. |
| Scaling / Spacing | Because the primary function is binocular/dichoptic rather than pure acuity, the scaling and spacing of the optotypes/symbols is determined by the underlying target material (e.g., tranaglyph sheets), not the flipper itself. What you should check: the target material should have appropriate spacing (for age/acuity) and should be compatible with red/green filters so that the red/green images cancel properly and the patient cannot “cheat” using one eye only. For example: the article states filters must match the colours used in the task. |
| Range of Acuity / Line Sizes | The flipper itself does not define a specific acuity range or line sizes (like “20/40”, “20/200”). Instead, the acuity target depends on the chart/reading material you pair it with. If you are using the flipper for reading tasks (paired with red/green bar reader) the acuity line size should match the patient’s corrected acuity, so that binocular/dichoptic training is meaningful (not just blur). For example the home-activities description: “hold the flipper … read a sentence … then flip … read another sentence.” |
| Testing Distance | If you are using the flipper for reading tasks (paired with red/green bar reader) the acuity line size should match the patient’s corrected acuity, so that binocular/dichoptic training is meaningful (not just blur). For example the home-activities description: “hold the flipper … read a sentence … then flip … read another sentence.” Some tranaglyph or vectograph setups might use near (~40 cm) or moderate distance, depending on therapy regimen. The product listing doesn’t always specify a single distance for the flipper by itself. If using reading material, you could set at e.g. 40 cm (16″) or the usual near working distance. For other charts, follow the chart recommendation. |
| Dimensions | Typical vision therapy flippers are compact handheld bars, maybe ~20-30 cm in length, with lens segments ~3-4 cm wide. For example, 38mm lens height is consistent. Ensure handle is comfortable, size appropriate for age group using it (child vs adult). |
| Mounting | The flipper is handheld — the therapist or patient holds it in front of the eyes, flips between red/green (or green/red) lenses. There is no fixed mounting to wall or head. |
| Features | The flipper itself doesn’t have a display. The display/target is separate (reading material, tranaglyph screen, vectograph). The flipper alters which filter/lens the patient sees through. For example: “A flipper with red/green lenses on top and green/red lenses on the bottom. If you’re pairing it with charts that require a holder, you’ll need to ensure the flipper can be held in the correct position relative to the target. Also that flipping action doesn’t disturb target alignment. |
| Accessories | Manufacturer product description may not list extensive accessories. Some vendors might include protective case, instructions for therapy, or maybe additional lens sets (less common for flippers). The Akriti site lists pack of 10 for purchase (bulk) but not accessories. If you buy as part of a vision therapy kit, the kit may include flippers plus reading bars, red/green glasses, etc. |
| Durability / Material Qualities | The flipper should be easy to hold and operate; flipping should be smooth and quick Lenses clearly marked (if applicable) to show red/green orientation, so therapist/patient knows which side is up/down. The device should align easily with the visual target (reading or chart) without causing discomfort or mis-alignment. Compatible with red/green glasses or the therapy filters being used; the red/green flipper lenses must match the other filters so that dichoptic separation works. The article emphasises that filters must match the colours used in the therapy task |
| Marker of Quality | Material quality: plastics/ABS handling frequent use, filters correct, no optical distortion. Good user reviews, clinic adoption, availability of service/spares. Bulk availability if used in clinic (Akriti offers pack of 10). |
