Product description
- Vision Therapy for Amblyopia & Diplopia: Improve binocular vision with red-green anaglyph glasses designed for treating amblyopia (lazy eye), exotropia, diplopia, and convergence insufficiency. Ideal for both kids and adults, these glasses support essential eye training and therapy exercises at home or in clinical settings
- Enhances Eye Coordination & Focus: Use with vision therapy cards, digital programs, or anaglyph exercises to strengthen eye teaming, depth perception, and visual tracking. These glasses support visual motor skills and are commonly used in orthoptic and optometric rehabilitation routines
| Topic | Discription |
| Purpose / Target Users | These reversible red/green anaglyph goggles are designed for orthoptic training and vision therapy (anti-suppression training, binocular vision training, ocular motor and accommodative exercises). Typical target users: patients with suppression of one eye (e.g., amblyopia, strabismus, binocular vision disorders) who need therapy to encourage use of both eyes or reduce suppression. Also used in vision-therapy clinics, orthoptic practices and sometimes home training kits. Not primarily a standard acuity test spectacle, but a therapeutic/diagnostic accessory. |
| Optotypes / Symbols | The goggles themselves do not provide optotypes or symbols; they are the filtering device. The actual optotypes/symbols (letters, figures, targets) come from associated charts or therapy materials (e.g., red/green reading sheets, anti-suppression charts) that are viewed through the filters. For example, red/green reading sheets are used with these goggles for amblyopia/strabismus training. For any specific test (acuity, stereo, suppression) you’ll need to check that test’s chart for the symbols. |
| Scaling / Spacing | Because the goggles simply filter the two color channels (red and green) and allow only one eye to see one channel and the other eye the other channel, the scaling and spacing of targets is entirely determined by the test or chart used behind them, not by the goggles themselves. If you are using a chart for binocular/training work, you should verify the chart’s scaling (size of optotypes, spacing between lines/figures, etc) and ensure the viewing distance matches that chart’s recommendation. Some catalogues list sizes of the goggles (frame sizes) but not the optotype spacing. |
| Range of Acuity / Line Sizes / Testing Distance | The goggles themselves do not define an acuity range or line sizes. They are used in conjunction with test charts. Thus you should refer to the specific test (e.g., anti-suppression charts, stereo tests) for acuity/line-size information. Typical tests using red/green filters may be used at near (for reading/training) or at distance depending on therapy goals. For example, some near red/green reading sheets are 8.5″ × 11″ and used at near distances. Testing distance should follow the chart/test instructions (e.g., 40 cm for near, 6 m for distance) depending on what you are doing. If you intend the goggles for standard acuity measurement, you’ll likely pair them with an acuity chart with defined line sizes. But the goggles themselves do not specify those. |
| Physical Size & Dimensions | Large size goggles: 2.8125″ × 1.9375″ (Approx 72mm × 50mm) Weight and other physical details not widely published; but many models mention “lightweight”. The size referenced is likely the lens/frame front size, not entire head-strap dimension. Elastic strap or arms may vary depending on model (some with elastic rather than temples for therapy |
| Mounting / Display Features | Mounting: These goggles are worn by the patient—they are not mounted to a chart/display. So “mounting/display features” largely refer to how the goggles attach or sit: Some models come with elastic strap for head size adjustments. Others may have temples (arms) like standard glasses (especially adult models). Display features: The goggles themselves don’t display anything—they are filters. The display (chart, screen, therapy game) must provide separate red and green images/targets. The goggles ensure one eye sees the red channel and the other sees the green channel (or vice-versa) thereby allowing dichoptic presentation or anti-suppression training. Reversible: Some models allow “reversible” meaning you can swap which eye sees red vs green by flipping the frame or switching lenses. This flexibility is valuable in therapy (so you can alternate eye assignment). Side-light/“peaking” control: Some models mention foam edges to prevent light leakage/peaking that could degrade dichoptic separation. |
| Included Accessories / Extras | Many models include: The goggles themselves (frame + red/green filters) Elastic strap or adjustable headband (depending on therapy vs adult version) Extras: Some goggles may have foam edging, latex-free strap, standard CE compliance. Small size goggles listing: “latex‐free and come with foam edges and a wide elastic band to prevent ‘peaking’.” In therapy kits: The goggles may be bundled with reading sheets, charts, or home vision therapy kits. Example: The home therapy kit from one catalogue includes reversible red/green anaglyph goggles among other items. But as a standalone product, the main accessory is the head strap or temples plus case. |
| Durability / Material Qualities | Typical material remarks include “lightweight”, “durable metal-frame” (for adult version) with spring-loaded temples. For example: “Durable metal framed reversible Red/Green Anaglyph glasses with spring-loaded temples. Storage case included.” Therapy versions: Some mention “lightweight plastic” or “plastic frame” with elastic strap. For example: “Basic red/green goggles with adjustable elastic, no arms for easy fitting on patients …” Quality features to check: Well-fitting strap/temples so goggles sit flat and stable (important for therapy). Foam or sealed edges to prevent light leakage/peaking (which can defeat the dichoptic separation). Lenses/filters should be properly aligned and the colouring should match the therapy needs (i.e., red filter blocks green channel, green filter blocks red channel). Frame durability: if used in clinic with children, should withstand frequent use. Cleanable surfaces (some reading sheets mention cleaning instructions). While the goggles themselves may not have listed instructions, you’ll want a material that can be gently wiped without scratching the filters. The presence of a storage case (for adult metal-frame version) suggests the manufacturer expects the item to be of premium quality and to require protection. |
| Usability / Marker of Quality | The straps/temples should allow easy fitting for both children and adults (or there should be size-variants). For example, small/large sizes are listed. The goggles must maintain correct optical alignment so that each eye sees only its intended filter channel; mis-alignment could reduce therapeutic effect. Comfortable enough for the intended session length. Materials and construction: metal-frame with spring-loaded temples, proper strap mechanisms, foam edges, adjustable band—these are indicators of better quality. |
