Because I spend a lot of time looking at computers as part of my job, I was suffering from chronic eye strain.
In severe cases, the eye strain causes the whites of the eyes to become bloodshot and teary.
At that time, this eye drop was recommended to me, so I bought it.
Use it when you want to refresh, such as during a break at work or at the end of the day, and your eyes will instantly feel refreshed.
In particular, when I use it when my eyes are so tired that they start tearing, the involuntary tears stop suddenly and my eyes no longer feel uncomfortable.
