Enjoy two colours in one frame with SunSwitch prescription glasses. An innovation in the eyewear industry, SunSwitch is a new, in-house brand of Feel Good Contacts. The frames change colour the moment they come in contact with sunlight and also switch colours when it’s cloudy. From a classic hue indoors to a vibrant shade outdoors, SunSwitch transitions into a completely new colour within seconds. However, they revert to its original colour when back indoors and away from the sunlight.
