Firstly, the marquee tool was used to select his left eye, duplicate it, and then transfer the layer over to his right eye. The eraser was used to correct the edges and skin colour to make it look natural. Next, I used the quick selection tool to select the left iris, create a new layer, cover his right eye, and merge the layers together. Then, I used the dodge tool to whiten the sclera of his eye. The first two steps (duplication and eraser) were used for his lips also. Lastly, I used the spot healing brush to clear up any imperfections on his face.
