What is the shelf life of Shining Eye Drops?

I believe that everyone must be familiar with Shining Eye Drops. Do you still remember Jay Chou and He Jiong who advertised Shining Eye Drops? Well, many friends must have bought Shining Eye Drops, so how long is the shelf life of Shining Eye Drops?

1. What is the shelf life of Shining Eye Drops?

   The packaging of Shining Eye Drops states that its shelf life can be up to two years, but I think everyone must be aware that this is in an unopened state, and it is not certain whether it can be kept for that long!
2. Shining eye drops can generally only be used for about one month after opening. Special attention should be paid: if the drops become cloudy, do not continue to use them no matter how long you have used them.
3. Be careful when using it, close the bottle cap tightly, and do not let the bottle mouth touch the eyelashes too much during use, as this will also affect its shelf life.
