3m LogMAR Chart

This chart is designed for use at a distance of three metres.
It consists of LogMAR letters (14 rows) printed on 510 x 510 mm stiff white board and comes framed in frosted aluminium. It is available with visual acuity specified using a 3 metre test distance (3/30-3/1.5) and with the conventional Snellen fraction notations (6/60-6/3).


Hi-Lo contrast LogMAR chart - $121.00 (incl GST)

This chart presents a side by side view of 2 LogMAR letter series (3/19 - 3/3.8). One is of normal contrast and the other of 10% contrast. It can be used reliably in low vision testing by reducing the test distance. The chart comes mounted in a frame for extra durability.


Melbourne Edge Test - $ 148.50 (incl GST)

Printed on Epson Premium Glossy Photo paper

The Melbourne Edge Test (MET) was originally designed by Jos Verbaken to permit fast and reliable assessment of the peak of the Contrast Sensitivity Function. The chart consists of a single luminance profile in four different orientations: horizontal, vertical, 45° left, and 45° right. The MET is a non-grating contrast sensitivity chart. This test measures the contrast threshold for a single luminance profile edge, which is an aperiodic stimulus. There is psychophysical evidence that the edge contrast threshold is determined by the most sensitive spatial frequency channel, the higher threshold for a single edge with respect to the better performance for optimum spatial frequency gratings being due to probability summation.
