Morphology
The meaning is directly derivable from 'eye' (vision organ) + 'chart' (a visual display), i.e. a chart related to the eye used for measuring vision. This noun–noun composition follows a common, cross-linguistic modifier pattern, so a B1 learner who knows both constituents would readily infer the intended meaning.
Etymology
Eye chart is a simple page or board with lines of letters that get smaller and smaller so an eye doctor can check how well you see. The words eye and chart make the picture clear: your eye looks at the chart, so it means a page used to 'measure how well you can see'.
