The reflections in sunglasses can have a big impact, both good and bad, on how a scene looks. If the reflection doesn’t match what the person is supposed to be looking at, it can be a distraction. Reflections can also foreshadow a coming moment, show choices and more.
To get the proper reflection you want, changing it in post is an easy and efficient option. Rocketstock has created a step by step tutorial to walk you through the process in After Effects.
Note: this technique is for stationary shots with the subject in a medium to close-up framing. Anything more elaborate, and you might need a different approach.
