We extended the refraction angle of the Eaton lens into arbitrary angles. Therefractive index of the Eaton lens is not analytical and can be obtained bynumerical calculations only except in the case of the retroreflector. Weintroduced an approximation for the refractive index of the generalized Eatonlens. It is simple but very close to the exact values obtained from numericalcalculations.
