Cardiff Acuity Test Set™ with 36 cards. The standard set covers 12 acuity levels from 20/160 to 20/12.5. This version also include a pair of 4608R Butterfly foamy occluding glasses. The Low Vision set covers 14 levels from 20/320 to 20/12.5. There are …

The test comprises 36 acuity testing cards at twelve levels. The test is prepared for preferential looking and presented in vanishing optotype format. The target cards are approximately 10.5 x 8 inches (265mm x 203mm) in size, are litho printed on paper and mounted on a plastic substrate.

The Cardiff Acuity Tests are designed especially for the hard to test age group, 12 months to 30 months. It uses familiar pictures and a procedure in the form of a game to attract and keep the attention of young children.

The Cardiff Test employs an up-down positioning of the target figures rather than the right-left separation (as is used in the Teller Acuity Cards™ II) so that the eye movements are easier to discriminate in cases of congenital nystagmus. Further, the Cardiff Test can be used in cases of suspected malingering as the patient’s eye movements are

The Cardiff Acuity Test was developed by Dr. J. Margaret Woodhouse, at the School of Optometry and Vision Sciences, Cardiff University in the UK. It has been rigorously validated and is now recommended by leading paediatric vision consultants worldwide.

The Cardiff card set in 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); Butterfly Occluder Glasses are also inlcuded.

The test uses pictures that will interest a child (house, car, duck etc.) positioned either at the top or at the bottom of an otherwise grey card. There are eleven visual acuity levels, with three cards at each level.

The Cardiff Test includes three cards at each acuity level, although only two are usually presented. This is so that once one card at a particular acuity level has been presented, the position of the next card to be presented cannot be predicted by either child or examiner. We have chosen to employ an up-down rather than a rioht-left

Summary: The Cardiff Tests of Visual Acuity and Contrast Sensitivity consist of 3 sets of 11 grey cards each with a picture at either the top or the bottom of the card. The cards are presented to a child in a sequence and if the child makes a clear, correct look (gauged by eye movements) at 2 cards in each set, the examiner proceeds to a higher ...
