Cardiff Pediatric Acuity Test474000
The Cardiff Pediatric Acuity Test was designed specifically for acuity measurement in children ages 6 months to 3 years. The test may also be helpful in other age groups for people with intellectual impairment, dementia, head injury, or stroke.
A study in Optometry and Vision Science compared the Cardiff Acuity Test and Teller Acuity Cards II in school-age children with visual, auditory, motor, and cognitive impairment and showed that both give similar estimates of acuity, test-retest reliability, and testing time. The Cardiff Acuity Test is half the cost of a full set of Teller Acuity Cards II while containing more cards with which to test acuity.
The Cardiff card set is composed of 36 cards providing 24 acuity levels that can be used at either 1 meter or 1/2 meter testing distance with acuity ranging from 20/160 to 20/12.5 equivalent (6/48 to 6/3.75); Flip Up Occluder Glasses are included.
475400 - The upgrade includes 3 cards each of level A (Fish), LVB (Sock), LVA (Apple) plus two dividers. Total of 9 cards. Case not included. (Not shown).
669800 - The Screener Set comes with a flip-up occluder, plastic dividers, and 24 cards with 8 acuity levels. (Not shown).
