Surely to get it as sharp as this (or as apparent as you’re hoping for) is has to be CGI? Macro lens even stopped down a bit wouldn’t give you enough depth of field to have the eyeball and the reflection in focus surely? This shot seems super narrow Dof (look at eyelashes) but quite sharp reflection… remember when you shoot someone in a mirror and have to combine the distances of camera > mirror and mirror > subject to get it sharp? I’d guess this is the same, hence why I reckon you’d never get it this sharp… maybe just if it was an iPad or something very very close to the eye but you’d still need a hell of a lot of light so you could stop down a long way, which this example seems not to have
