Eye drop recommendation

I have dry eyes and frequently use eye drops. At first, I used the regular eye drops provided by the hospital. Then, a friend recommended a different eye drop they use, and I tried it for the first time—Friends Eye Drop. My friend said it gives a cooling sensation, so I was recommended to try it. I was surprised when I saw this eye drop—such a product exists... After trying it, I felt that the cooling sensation improved my mood. Upon closer inspection, I found that there are various products with different levels of cooling sensation, ranging from mild to strong. Now, I alternate between products that provide a moderate and a strong cooling effect depending on the situation, and I am satisfied.
