According to scientific research therapeutic filter lenses increases the contrast and decreases the required time in order to adjust variable light conditions in some retinal diseases. Therapeutic filter lenses that are intended for medical usage completely emits all visible light withing the spectrum.
There is no standard procedure or objective criteria for therapeutic filter lenses to be prescribed. The right kind of therapeutic filter lenses for degenerative eye disorder can be picked be trying of all the options. Patients compare and evaluate the comfort provided by different options of therapeutic filter lenses. Many patients for different light conditions need different color of therapeutic lenses. The success rate is high due to minimization of very shiny, hight contrast light shocks.
The lenses filters 450nm, 480nm, 500nm, 540nm, 550nm and 600nm wave lengths and has the feature to block visible lights. As shown on the graphs the below mentioned disorders corresponds with the filter needed to help with the vision complications. The goal is to increade the life quality of the patient by reducing the light sensitivity.
