Researchers discover way to make cells in the eye sensitive to light

...ntosa. Retinitis pigmentosa is a form ofhereditary blindness where the rods and cones are destroyed, but therest of the eye and retina remains intact. By switching on themelanopsin it could be possible to restore the eyes ability to respondto light.Although making cells in the eye responsive to light is not a ...
