1. A method of making a lensed connector comprising:
inserting a light occluding agent into at least one hole of a ferrule made of glass, wherein the at least one hole extends partially through the ferrule from a first surface;
applying UV light onto the first surface of the ferrule such that the light occluding agent prevents a portion of the ferrule from being treated by the UV light, thereby forming an untreated portion of the ferrule;
removing the light occluding agent from the ferrule; and
thermally developing the ferrule such that the untreated portion of the ferrule forms a dome shaped lens structure protruding from a second surface of the ferrule, wherein the second surface is opposite the first surface.
