These Rohto Lycee eye drops are very difficult to get. They are only available in Japan (freely available in most pharmacies). So when I was in Japan, I searched for it, and the moment I spotted it, I quickly got a box. The pink version is meant for contact lenses, to reduce the redness in the eyes. I LOVE the packaging. The pink box and the cute bottle are very unique. However, I found it hard to justify the price since there's only a small bit of eye drops inside each bottle. I tried it a few times, and every time I came away disappointed. I know that the solution will sting a little, but it was very painful. Also, while the pain subsided, it did not go away. I found that my eyes were even drier than usual after a day. I still have the bottle, and I'm willing to try it out again next time. But form now, I absolutely cannot justify this purchase, and I'm very disappointed with the product.
