No, you can't use this kind of eye drops. I have seen the warnings of this kind of eye drops. it is said you should ask a doctor before using it if you have high blood pressure. So I think maybe they will have some side effects on people who have high blood pressure. Besides, it also said that if you have other kind of problems such as heart disease, trouble urinating, narrow angle glaucoma, you also should ask a doctor first. If you are sensitive to some ingredients in this kind of eye drops, you'd better not use them. And do not use this solution if they change color or become cloudy.
