Introducing the Y003 Portable Hidden Strabismus Detector: Uncover and Diagnose Heterophoria with Precision
Discover the Y003 Hidden Strabismus Detector, a must-have diagnostic tool for optometrists and ophthalmologists. This advanced instrument accurately measures latent strabismus (heterophoria), ensuring precise eye alignment assessments.
Key Specifications:
- Measurement Range: 0Δ to 20Δ (Δ = prism diopter)
- Scale Graduation: Each division equals 1Δ for high-resolution readings
- Simple, Step-by-Step Operation Guide:
Achieving reliable results is straightforward with our Y003 Detector. Initial Setup: Hold the instrument by its handle and align the indicator line with the "0" mark on the reading ring. Patient Positioning: Position the patient to gaze at a light source 3 to 5 meters ahead, looking through the instrument with one eye while the other views the light directly. Observation & Interpretation: One eye will see a bright red streak, while the other sees a light spot. Misalignment indicates the presence of phoria. Measurement: Rotate the handwheel until the red streak aligns with the light spot, and read the heterophoria degree on the ring.
Vertical Phoria Measurement:
After zeroing, position the instrument vertically for the eye being tested. A horizontal red streak will be visible through the instrument. If the light spot appears above or below the streak, it indicates left or right hyperphoria, respectively. Rotate the handwheel to intersect the streak with the spot and read the degree of vertical phoria.
Why Choose the Y003 Hidden Strabismus Detector?
