The visual fields of 10 healthy myopic patients were compared using hydrogel lenses with a clear pupil and an opaque colored portion covering the iris and clear hydrogel lenses. Significant (>10°) field loss was found in all cases when the midperipherally colored lenses were worn. Patients interested in these lenses should be advised of this slight reduction of peripheral vision before fitting.
