In this work we offer a comprehensive optical investigation of the optimally hole-doped Ba_0.6K_0.4Fe₂As₂ over a broad spectral range, as a function of temperature and of tunable applied stress, which acts as an external symmetry breaking field. We show that there is a large electronic nematicity at optimal doping which extends right under the superconducting dome and implies an anisotropy of the superconducting energy gaps.
