Reviews

Elena, 32 years old
I constantly work at the monitor, so I began to notice that my vision is falling, the proteins are red and inflamed, and I suffer from dryness and discomfort. The ophthalmologist recommended a course of Phenylephrine Optic drops for 3 weeks. I dripped my eyes before going to bed 1 time, which is very convenient for my work. Among the disadvantages is a slight burning sensation that lasts 5-6 minutes. A small child is unlikely to withstand such a procedure. But the result was very satisfactory to me, so the review of the medicine is positive.
Victor, 27 years old
After a trip to nature, I developed conjunctivitis. I delayed the treatment, so the disease became severe. The doctor prescribed several drugs, among which there were drops of Phenylephrine. I used it before bed, but this is good: the medicine stung my eyes, so I had to keep them closed for a long time. I noticed improvements after a few days, redness and swelling disappeared, vision became clearer. The result has been achieved, so I recommend the medicine.
