Product description
- The Red & Green Reading Bar (Large) is a wide anaglyph reading tool used with red-green glasses to strengthen anti-suppression and binocular balance during near reading and tracking tasks. The larger bar covers a broader portion of text, making it easier to run longer, smoother reading drills (and to monitor line-by-line stability) while giving immediate feedback—if one eye suppresses, parts of the text may fade or “disappear” in one color. It’s ideal for clinic protocols and supervised home programs aiming to build comfortable, sustained single vision for real-world reading.
- What it trains: Anti-suppression, binocular balance, reading stability, and visual stamina
- Large format advantage: Wider coverage over text → smoother line tracking and better support for longer paragraphs and larger books
- How it’s used: Wear RG glasses → place bar over the reading line at ~40 cm → read continuously while ensuring both colors remain visible
- Instant feedback: Color drop-out or missing letters indicates suppression; balanced visibility and luster suggests both eyes are working together
- Progressions: Increase reading duration, decrease font size, add metronome pacing, or combine with vergence tasks (tranaglyph/prism flipper)
- Who it suits: School-age children, teens, and adults in VT—especially those with reading fatigue or unstable binocular control
- Pairs well with: Adult/Pediatric RG glasses, RG flipper, variable tranaglyph, Hart chart near, fixation stick
- Care: Keep the surface clean and scratch-free; wipe with a soft cloth; store flat away from heat/sunlight to prevent fading
| Topic | Details |
| Purpose / Target Users | The Red/Green Bar – Large is a vision therapy tool used for anti-suppression training and binocular vision development. It helps encourage both eyes to work together by presenting different visual information to each eye when used with red/green anaglyph glasses. It is typically used while the patient reads text or views images, allowing therapists to train binocular coordination, suppression control, and reading stability. Target users include patients with binocular vision disorders such as amblyopia, strabismus, or suppression, under supervision of optometrists, orthoptists, or vision therapists. |
| Optotypes / Symbols | The Red/Green Bar itself does not contain optotypes. It functions as a colored overlay filter placed above reading material. The actual optotypes (letters, words, pictures, or symbols) come from the underlying reading sheet, chart, or therapy material used during the exercise. |
| Scaling / Spacing | The bar does not define scaling or spacing. Text size and spacing depend on the underlying reading material used during therapy. The bar simply overlays the material and separates visual input into red and green channels for each eye. |
| Range of Acuity / Line Sizes | The device itself does not define acuity levels. When used with reading sheets or therapy charts, it typically works with near print sizes around 20/30 to 20/50 equivalent depending on the therapy material. Actual acuity range depends on the size of the text or images used beneath the bar. |
| Testing Distance | The Red/Green Bar is designed for near vision therapy tasks, typically used at normal reading distance (approximately 40 cm / 16 inches). During exercises, the bar is usually held about 1 inch above the page to allow proper separation of the red and green visual channels. |
| Physical Size & Dimensions | The Large Red/Green Bar measures approximately 19.5 × 25 cm (about 8 × 10 inches). This size is designed to cover most standard reading sheets or therapy pages used in binocular vision exercises. |
| Mounting / Display Features | The bar is designed for handheld overlay use. It is positioned slightly above the reading material or therapy chart. It is not mounted to walls or stands, and instead is used directly with printed pages, worksheets, or therapy materials. |
| Included Accessories / Extras | The standard product typically includes the Red/Green Reading Bar (Large) only. Additional items such as red/green anaglyph goggles, therapy reading sheets, or vision therapy charts may be used with the bar but are usually supplied separately. |
| Durability / Material Qualities | The bar is generally made from transparent plastic or acrylic with printed red and green filter sections. The material allows easy cleaning and repeated clinical use. The surface should be cleaned using a soft cloth with mild cleaning solution, avoiding abrasive materials that could scratch the plastic. |
| Usability | The Red/Green Bar is simple to use during reading-based vision therapy exercises. By overlaying the bar above reading text, each eye receives different visual information through the red/green filters. This encourages binocular cooperation and reduces suppression while the patient performs reading tasks. |
| Marker of Quality | Quality indicators include accurate red/green color separation, clear transparent plastic, smooth edges, and adequate size to cover standard therapy reading material. Durable construction and compatibility with red/green anaglyph goggles and therapy charts make it a reliable tool in professional vision therapy programs. |
