The Kay Letter Test 6 Metre Acrylic LogMAR Chart provides 6 Sloan letter optotypes in LogMAR sizing and Snellen equivalent sizes from 0.8 to -0.2 LogMAR (6\/38 to 6\/3.8 Snellen). The six letters have been carefully chosen to provide similar legibility with the need to differentiate similar shapes. This also gives the option to use a matching card<\/a> if required.<\/p>\n

Sizes 0.3 to -0.2 have 5 letters per line, giving the option to assign a LogMAR acuity score to each letter for the best repeatability. The LogMAR and Snellen scores provided on this chart are specific for a six metre test distance. If you use this chart at a different distance the scores will need to be adjusted accordingly. To test for acuity sizes worse that 0.8 (6\/38) we recommend that you change your test distance to three metres which will add 3 additional LogMAR sizes. See more information in the scoring tab.<\/p>\n

The Kay Letter Test 6 Metre Acrylic LogMAR Chart fits a standard large illuminated LED light box and four-sided rotating test type.
\n<\/strong>From the drop-down menu above, you can choose to purchase the chart together with the light box, light box with carry handle or light box with a wall bracket.<\/strong><\/p>\n

The lightweight LED illuminated box holds a single vision testing acrylic panel and has a spotlight below the panel. A manual side switch will select which section is illuminated. It comes with a 12V medical power plug and 2 metre lead to the right side of the unit. The box is white in colour and can be wall-hung, or stood on its feet plus integral stability bar. The LED illumination strips should last for 30-50,000 hours. Replacements can be fitted by the manufacturer.<\/p>\n

This standard size acrylic chart will slide up for easy replacement, if required.<\/p>\n
