A nontoxic, nonirritating fluorescent stain, bis-(N, N-bis-(carboxymethyl)-aminoethyl)-fluorescein tetrasodium salt (Fluorexon) (BCA), has been evaluated. Because it does not readily stain hydrophilic, soft contact lenses, it can be used to assess the tear exchange around a soft contact lens while on the eye of a patient.
