- Set of 2 Vision Therapy Cards – Includes 1 Dot Card and 1 Barrel / Color Convergence Card.
- Dual-Sided Barrel / Color Convergence Card – Green dots on one side, red dots on the other for effective fusion training.
- Eye Exercise Tool – Helps treat convergence insufficiency, exotropia, and related binocular vision issues.
- Durable Material – Made of strong, hard plastic, ensuring long-lasting use.
| Topic | Discription |
| Catagory | Vision Therapy |
| Convergence / 3‑Dot Card Purpose | To test and train convergence (eye alignment / binocular vergence) by having the patient fixate sequentially on three dots. |
| Item Weight | lightweight |
| Target Users | Patients undergoing vision therapy, especially those with convergence insufficiency or binocular dysfunction; used by optometrists, orthoptists, vision therapists. |
| Optotypes | Dots There are no letters, numbers or standard vision chart symbols; it’s purely dots. |
| Line Sizes | This card is not meant to measure visual acuity across lines or sizes; it’s a convergence / alignment tool. |
| Testing Distance | Very near—held close to the nose (i.e. “near point” use) |
| Dimensions | 5.5″ H × 2.5″ W (approx) |
| Mounting / Display | Handheld / free‑space use |
| Features Included | Double‑sided printing (one side red, one side blue) The two sides allow for red/blue fusion or alternate viewing, which is useful for testing suppression or binocular fusion. |
| Material | Printed on some form of coated cardstock (or card material) |
| Usability / Marker of Quality | Ease of use: Straightforward — place cards in front of eyes, ask the patient to fuse.circle images, see the central word, adjust position until alignment is achieved. Because it’s a simple device, minimal training is needed for basic use. Precision: The inclusion of small hash marks is a marker of a more precise design, allowing therapy to detect small fixation disparity Flexibility for therapy: Because these are free‑space cards, they allow more natural fusion training vs forced dichoptic setups, which is considered beneficial in therapy settings. Limitations: The lack of quantified steps, lack of variant sizes, and absence of an embedded frame or mount means the therapy depends more on operator discipline and consistency. Also, without protective casing, wear over time may reduce accuracy. |
