Reviews
Victor, 36 years old
I work at a computer, I have never had vision problems. But a month ago I began to notice that my eyes quickly get tired and turn red in the evening. There is no free time, so I consulted at the pharmacy, where I was offered to try Visoptic drops. What can I say, the drug is not bad, it quickly relieves fatigue and irritation. The only thing I didn’t like was that immediately after application, the eyesight temporarily deteriorates. It is clear that this is not critical, but at work sometimes you have to suddenly get behind the wheel of a car. Once I had to wait 20 minutes for my vision to recover. Overall, my review is positive.

Visoptic are wonderful drops, which I met recently. My eyes are very sensitive, and after giving birth they became inflamed from minimal exposure to wind. At first, Vizin saved herself, but the price for him is already very high. I began to look for a replacement. A friend advised me to try Visoptic. I bought it and did not regret it. I use the drug in a course of 1 drop 3 times a day for a week, and then a month break. This scheme suits me very well. The medicine is effective and safe, there have never been any complications. As for my eyes, they respond remarkably to treatment. I have forgotten what burning, redness, lacrimation are. Now I boldly go outside with my child in any weather. I recommend these drops to everyone, they help perfectly.
