title: Protective spectacles for retinitis pigmentosa patients.
abstract: On the hypothesis that ophthalmic filters with appropriate light transmission characteristics may be beneficial in retarding the progress of retinal degeneration in early retinitis pigmentosa, the characteristics of several plastic and glass filters have been evaluated. A dark brown plastic goggle has been found which meets the theoretical criteria previously postulated for such protection. Its characteristics and those of other filters are compared with a lens which was specially designed for RP protection and was previously reported on by Adrian and Schmidt.
