3 Copy and flip features

As with the partially covered left eye in the original image, sometimes we need to re-use other parts of the image to fix issues. You can make a selection of the intact right eye here with the Lasso Tool, then copy it to a new layer (Ctrl/ Cmd+J). Next, flip it and move it over to the other eye to rebuild the details lost behind the hair. Add a Layer Mask and paint with black to blend the edges.
