When it comes to choosing an eye brightener from Thrive, it's important to consider your specific needs and preferences, rather than focusing solely on eye color. However, there are certain shades that tend to complement brown eyes beautifully.

For brown eyes, I would recommend considering the Thrive Eye Brightener in the shade "Champagne Shimmer." This shade has a warm, golden undertone that can enhance the natural warmth and depth of brown eyes. It provides a subtle brightening effect that can make your eyes appear more awake and vibrant.

Remember, personal preference and individual skin tone can also play a role in determining the best shade for you. It's always a good idea to try different shades and see which one you feel most confident and comfortable wearing.
