Charts and Tests

LogMAR Charts

 

The LogMAR chart has rapidly become the test format of choice for clinicians. The Thomson Test Chart includes a huge range of options for LogMAR charts including ETDRS, Linear, Crowded Linear, Column etc. LogMAR charts are available in 12 different optotypes including Sloan, British, Kay, Tumbling E, Landolt C, Makaton, Sheridan Gardner and in a number of different language fonts including Gujarati, Arabic, Punjabi and Hebrew.

Snellen Charts

 

12 different optotypes can be displayed in the traditional Snellen format including British, Sloan, Sheridan-Gardner, Landolt Cs, Tumbling Es, Kay pictures, Numbers, Gujarati, Punjabi, Arabic and Hebrew. A single row or column can be shown and a range of cursors are available to isolate specific letters or rows.

Single Letter Charts

 

It is sometimes easier to show a single letter, particularly when testing children and those with learning difficulties. The size of the letters can be changed in 0.1 logMAR steps and crowding bars can be added. A wide range of optotypes can be displayed in single letter format.

Fixation Targets

Test Chart LITE includes over 200 different images for fixation including photographs, cartoons and a selection of spots and crosses. The images are arranged in groups and a slide-show of the images within a group may be shown during retinoscopy or ophthalmoscopy for example. Add your own images and videos if required.

UK Number Plate Tests

The “number” plate test remains the only statutory test of vision required for driving in the UK. Test Chart 2020 is capable of exactly replicating a series of front and rear number plates using the exact fonts and character spacing. The number plates can also be presented against a variety of backgrounds to simulate real world conditions.
