Abstract: An eye chart uses a series of sinusoidal lines spaced at intervals selected to discriminate between normal vision and vision impaired by the presence of a cataract. Groups of sinusoidal lines have progressively different distances between the series with one series representing normal vision with the space between the lines growing progressively further apart to indicate the advancement of the cataract. A user counts the number of lines of the group that is clearly distinct. A user with normal vision will be able to count the number of lines, while a person with cataracts will require the space between the lines to be further apart in order to count depending on the stage of cataract development. A light source may be used to indicate night vision problems. A user can record the progression of the cataracts by tracking any changes over time. Different shapes and letters may be used.
