As a result, the Bianchi Type I model, being the simplest anisotropic extension to the standard Friedmann-Lema\\^itre-Robertson-Walker metric has been extensively studied. In this work, we show how the recombination history should be modified in an anisotropic universe and derive observables by considering the null geodesic.
