Product description
- Vision Therapy Tool for Eye Exercises: JUTRON VISION Red and Green Reading Bar with Z Axis Chart is ideal for vision therapy and eye exercises. It helps improve eye movement, focus flexibility, and visual skills during near and distance testing. Perfect for optometrists, therapists, and home vision training
- Near and Distance Accommodation Testing: The Z Axis Accommodative Rock Chart trains the eyes to shift focus quickly between near and distance objects. This tool supports accommodative facility testing and helps manage eye strain, convergence insufficiency, and focusing disorders in children and adults
| Topic | Discription |
| Purpose | To train accommodative facility / control by having patients shift focus between near (transparent near card) and the overlapping distant chart, emphasizing the z‑axis (focus) rather than eye movements. It is not meant for general screening but for therapeutic training / optometric / vision therapy settings. |
| Target users | Usable as a home exercise or in-office vision therapy tool for people with accommodative dysfunctions, emerging presbyopia. |
| Optotypes / Symbols | Uses conventional optotypes (letters / characters) on the near chart, similar to standard near vision charts. The publicly available listing does not specifically enumerate the font, symbol set. |
| Scaling / Spacing | The near card is static (fixed optotype sizes) and overlaid over the distant chart. The “rocking” effect is achieved by switching focus between the near card and the distant background, not by graduated scaling on the near chart itself. Because the design isolates accommodation, the near chart is not a variable scaling chart; spacing is typical to a near vision chart. |
| Testing Distance | The near chart is placed directly in front of the distant chart (i.e. very near) so patient alternately focuses on the near card vs the distant chart behind it. |
| Mounting | The near chart is a free card / overlay (transparent) that is placed over or in front of a distant chart It is not meant to be wall-mounted by itself, though the distant chart is mounted normally and the near card is held or fixed in front. |
| Features | The “rock” (accommodative shift) mechanism: you can see one plane in focus while the other blurs, helping the patient isolate focusing control. The listing indicates “patient‑oriented instructions included.” The listing does not indicate advanced features (e.g. randomization, variable transparency, backlight) beyond the basic rock overlay concept. |
| Accessories | The product is the near chart (paper) overlay version (SKU 710514) of the Z‑axis set. The description suggests it is part of a set (near + distance charts). |
| Durability / Material Qualities | Material is paper (the listing says “paper near chart”) Because it is paper, the chart is more vulnerable to wear, creasing, fading with use over time. The listing does not state whether the paper is laminated, coated, or of a heavier grade. |
| Usability / Marker of Quality | Conceptually strong: isolates accommodation (z‑axis) to help patients experience focus shift. Simple to use: overlay, focus switching, suitable for home exercises. The product is offered by a known vision therapy supplier (Good‑Lite via Jutron). The availability of both near and distance versions in the Z‑axis line suggests a modular / system approach. |
