- Material: The frames are often made of durable, lightweight plastic (ABS+PC material), and the lenses are typically high-quality acrylic or PET plastic.
| Topic | Discription |
| Purpose / Target User | Purpose / Target User Purpose: Used in binocular vision therapy, stereopsis (depth perception) testing, and anaglyph-based exercises. The glasses help each eye view a different image (one through the red lens and one through the blue lens) to train eye coordination, fusion, and depth perception. Target Users: Optometrists and vision therapists, Patients with binocular vision disorders, Individuals with amblyopia or convergence insufficiency, Students and children undergoing vision therapy |
| Optotypes / Symbols | Not applicable (the glasses themselves are used with optotype charts, stereograms, or digital vision therapy programs that present red-blue images). The lenses allow selective viewing of red and blue patterns for exercises using anaglyphic symbols or shapes. |
| Scaling / Spacing | Not directly applicable, When used with red-blue anaglyph charts, scaling depends on the test or program design—the glasses simply enable proper eye segregation of images |
| Range of Acuity / Line Sizes | Not applicable to the glasses alone. Compatible with various acuity ranges and stereo tests (from coarse to fine disparities, depending on test type). |
| Testing Distance | Typically 40 cm (near tasks) for most binocular training or anaglyph exercises. Up to 3 m or more (distance tasks) when used with wall charts or projection-based stereopsis tests. |
| Physical Size & Dimensions | Adult size: Approx. 14.5 cm (width) × 4.5 cm (height) × 14 cm (temple length) Pediatric size: Approx. 12.5 cm (width) × 4 cm (height) × 12 cm (temple length) Lightweight frame designed to fit comfortably on face shapes of different sizes. |
| Mounting / Display Features | Reversible Design: Can be worn with red lens on right or left eye, depending on test requirements. Single-piece molded frame — no screws or hinges, ensuring durability and easy handling. Some models feature clip-on designs for users who wear prescription spectacles. |
| Included Accessories / Extras | Usually supplied individually, but may come with: A protective pouch or sleeve Instruction leaflet for orientation and usage Occasionally part of a complete vision therapy kit |
| Durability / Material Qualities | Made from impact-resistant acrylic or polycarbonate lenses with plastic frames. Scratch-resistant, lightweight, and flexible construction for repeated clinical use. Lenses are optically balanced to ensure clear separation of red and blue images. Withstands cleaning and disinfection without distortion or warping. |
| Usability / Marker of Quality | Reversible orientation increases versatility for different test types. Comfortable and reusable, suitable for both clinic and home therapy. Optically accurate coloring ensures correct image filtration.CE-marked or ISO-certified products are considered markers of quality in optical devices. Ease of cleaning and durability are key quality indicators for professional-grade models. |
