Friends Eye Drop is good.

Friends Eye Drops come in three types: Cool High, Cool, and Pure. There is no difference in efficacy and performance; the only difference is in the sensation of coolness and freshness.

You can think of the level of coolness increasing in the order of Sun, Cool, and Cool High.

For these reasons, I also use Friends Eye Drop medication. I buy different types and use them according to my level of fatigue.

First-time users are recommended to follow the order.

When experiencing eye discomfort or a foreign body sensation, especially when tired, I often use it. You can put 2 to 3 drops up to 5 to 6 times a day.
