Description

The only symbol test of its type with the stated objective of calibration targeted to equal Sloan letters used in the ETDRS charts. This uniformity is especially important when taking patients from symbols to letter tests. Other tests are either much easier than ETDRS charts or they are outdated and no longer relevant. Both are very significant factors when a child has an eye disorder or amblyopia and they advance to clinical letter charts.
