Infant Vision Testing Device Enables Automatic Interpretation of "eye Tracking" Results.

Currently, there are two main methods for screening infant vision in clinical practice:

1) Refractive screening instruments, primarily used to detect myopia, hyperopia, astigmatism, etc., but cannot directly assess the brain's actual ability to recognize and distinguish objects, i.e., "visual acuity." A child with normal refractive status may still have poor vision due to other reasons.

2) Selective viewing methods (such as the TEELER visual acuity card), while directly assessing visual acuity, are cumbersome and time-consuming, requiring simultaneous card manipulation and observation of the infant's reaction. The interpretation of results is highly subjective, relies on experience, and demands a high degree of cooperation from the infant.

Therefore, the market urgently needs a vision testing solution that requires no active cooperation from the child, provides objective results, and allows for rapid testing. Infant vision testing instruments have the following outstanding features:

* From 3 months old: Suitable for infants aged 3 months and above;

* Automated process: Captures visual tracking behavior and automatically adjusts the grating level;

* Enhanced grating vision: Improves success rate; grating targets combined with dynamic targets enhance attraction for children;

* Short testing time: Results are output after 3-5 fixations; the initial grating difficulty can be set according to the child's age.
