Rohto Z Pro is an eye drop that is designed to provide relief for discomfort, tiredness, and overworked eyes. It is a multi-functional, super cooling Japanese drop that effectively reduces the feeling of eye fatigue and prevents damage from ultraviolet rays, for example, during outdoor sports. The product contains three active ingredients that are effective for fatigue, which are tetrahydrozoline hydrochloride, neostigmine methyl sulfate, and zinc sulfate hydrate. Other ingredients include boric acid, borax, l-menthol, d-camphor, peppermint oil, propylene glycol, edetate Na, polyoxyethylene hydrogenated castor oil, hypromellose, chlorobutanol, and pH regulator.

According to a review, Rohto Z Pro provides a refreshing feeling that awakens the tired eyes of modern people. However, another review describes the product as kind of like pouring acid into your eyes, but good. It is important to note that the product should not be used in case of hypersensitivity to any component of the preparation. Additionally, users should not touch the eye with the tip of the bottle and should keep the product out of reach and sight of children.
