Why you need it:
It makes your eyes whiter-than-white, it looks great on your vanity and it's cool and gently minty, which is much more pleasant than it sounds. (You minty eye drop people know what I'm talking about!)
Why I love it:
What is wet and pink and smells like roses? These eye drops from Japan. Not only do they work like a charm, giving you bright white eyes, they are also the chicest looking eye drops you will ever find. And they look suspiciously like the Chanel no. 5 bottle, no?
