Pediatric Opthalmology, Low Contrast
4M SLOAN Revised Chart 2.5 Percentage
Contrast Sensitivity plays an intricate part in everyday life. Testing contrast sensitivity helps to establish a record of what is normal for each patient, since everyone’s contrast sensitivity is unique. After establishing this accurate record for the patient, pinpointing abnormalities will be easier and can lead to quicker detection of vision problems. Abnormal contrast sensitivity results can help detect early signs of diseases such as Parkinson’s, Glaucoma, Cataracts and Glare problems, among many others.

Low Contrast, Pediatric Opthalmology
Mayer Kran Double Happy Low Contrast Test
The Mayer-Kran Double-Happy Low Contrast Test is intended for children and older individuals who are unable to name or match letters, that is, individuals who cannot be tested with standard letter contrast tests. The test cards are printed with a smiling schematic face offset from the center of the card; the face is identical when the card is rotated 180 deg. This format is like the Teller Acuity Cards* and enables testing using a similar procedure. The M-K Double-Happy Contrast Test is offered with two options: The Screening Set consists of 6 cards varying in Weber contrast: 89, 36, 25, 12.6, 6.3, 3.2, 2.2 The Full Set The M-K D-H full test set consists of 16 cards: 15 cards are printed with a schematic smiling face and the 16th card is blank. The contrast values are varying in Weber contrast: 89, 71, 50, 36, 25, 17.8, 12.6, 8.9, 6.3, 4.5, 3.2, 2.2, 1.6, 1.1, 0.8, Blank

Grating Acuity, Pediatric Opthalmology
OSU Ohio Contrast Cards Set of 11 Cards
For the Ohio Contrast Cards contrast sensitivity test, we chose a very low spatial frequency square wave because human contrast sensitivity, when measured with square-wave gratings, is empirically high and constant over a wide range of very low spatial frequencies. 5,17–19 Therefore, the visibility of a square-wave grating does not depend very much on spatial frequency over this range (red squares and it is much closer to the peak value of the contrast sensitivity function than what is reported for sine wave stimuli (compare red squares and blue diamonds. A, which we show because those authors also used large stimuli and unlimited viewing time; see also Carney et al. 20 and Watson and Ahumada 21. The red curve.

Pediatric Low Contrast Near
Pediatric Near Contrast Test Booklet with Contrast sensitivity levels of full Contrast (100%), 25%, 10%, 5%, 2.5% and 1.25% proportionally spaced (LogMAR) lines ranging from 20/400 to 20/16 using Michelson measures. One side of each page provides LEA SYMBOLS for testing of 3 to 5 year olds. The reverse side shows LEA NUMBERS for testing 5 to 8 year olds. Near Contrast testing provides an efficient means to detect or track ocular pathologies, including glaucoma, ARMD, diabetic retinopathy, cataract, and keratoconus. Low Contrast acuity loss measurement can used to demonstrate progress in disease treatment and help children’s parents understand the need for continued support.
