ASF Cardiff Acuity Card Set

The ASF Cardiff Acuity Card Set is a specialized vision chart designed for the assessment of visual acuity in challenging patient populations. It is primarily utilized for infants aged 6 months to 3 years, as well as nonverbal patients. The test is also beneficial for individuals with intellectual impairment, dementia, head injury, or stroke. This set employs the preferential looking principle, where an examiner observes a patient's involuntary eye movements to determine their visual acuity.

The Cardiff Acuity Card Set features laminated cards that are digitally printed for enhanced accuracy and durability. The cards are litho printed on paper and mounted on a plastic substrate, with a color-coated surface. The design incorporates the vanishing optotype principle, where target figures blend with the grey background at the acuity threshold, allowing for the assessment of resolution, detection, and recognition acuity.

This medical device holds US FDA approval, ensuring its adherence to regulatory standards for clinical use. Each set typically includes occluding glasses to facilitate accurate monocular testing.
