To choose a biocompatible multipurpose solution for a particular lens brand: Print the Staining Grid
      (landscape format suggested)

    1) Find the lens material (if it has been tested) in the first column of the grid.
    2) Follow across that row and select a solution which results in minimal corneal staining (i.e., green zone).

Note: Clicking on a percentage inside a cell of the Grid gives more information about that particular study's results.
