TopicDiscription
CatagoryVision Therapy
Convergence / 3‑Dot Card PurposeTo test and train convergence (eye alignment / binocular vergence) by having the patient fixate sequentially on three dots.
Item Weightlightweight
Target UsersPatients undergoing vision therapy, especially those with convergence insufficiency or binocular dysfunction; used by optometrists, orthoptists, vision therapists.
OptotypesDots
There are no letters, numbers or standard vision chart symbols; it’s purely dots.
Line SizesThis card is not meant to measure visual acuity across lines or sizes; it’s a convergence / alignment tool.
Testing DistanceVery near—held close to the nose (i.e. “near point” use)
Dimensions5.5″ H × 2.5″ W (approx)
Mounting / DisplayHandheld / free‑space use
Features IncludedDouble‑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.
MaterialPrinted on some form of coated cardstock (or card material)
Usability / Marker of QualityEase 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.
