Eye drops "Vizin" - a real salvation for people with eye diseases. It is also an indispensable tool for those who wear contact lenses. Drops allow you to moisturize the mucous membrane, narrow the vessels, relieve tension from the eyes. In this article you will learn about the methods of using "Vizin", its positive and negative qualities, cost and recommended dosages. Also reviews about "Vizin" will be considered.
Eye drops "Vizin" classic
From the moment of release, the drops were called "Vizin". However, a few years later there was a rebranding and the varieties "Vizin Pure Tear", "Vizin Allergy" appeared, but the production of classic drops remained.
The main active substance of the eye drops "Vizin" is tetrizoline. It has a local vasoconstrictor effect - it is thanks to this effect that drops relieve redness of the eyes. Also, this component has a moisturizing effect on the mucous membrane. Tetrizolin has a mild anesthetic effect, reduces itching and burning after injuries of the cornea and eyeball.
In addition, this substance has the following properties:
- Reduces the secretion of intraocular fluid, thereby reducing lacrimation.
- It has a local effect for three to four hours.
- Promotes the disappearance of blood vessels and gives the eyeball a beautiful, healthy shade.
After four hours, the effect of terizolin passes, and blood vessels again appear on the surface of the mucosa, since Vizin does not act on the cause of intraocular pressure and practically does not affect the optic nerve and arteries.
Disadvantages and side effects
The main drawback of drops (and reviews about Vizin confirm this fact) is that a pronounced vasoconstrictor effect significantly impairs the supply of oxygen to the eye tissues. This leads to even more reddening of the eye after the cessation of the drug.
Prolonged continuous use of drops can provoke the development of glaucoma, cause drug addiction. Ophthalmologists do not recommend using the drug on an ongoing basis for longer than one month. Be sure to take breaks to give the vessels time to return to their usual mode of operation.
Release form, price and reviews
Instructions for use with "Vizin" reports that the drug is made in the form of a solution of 15 ml in plastic sterile bottles (1 ml - 0.5 mg of tetrizoline hydrochloride).
Vizin drops are manufactured by Canadian pharmaceutical company Keata Pharma inc.
The price varies from two hundred to five hundred rubles, which depends on the pharmacy network and the region of the place of purchase. Drops of "Vizin Net Price" are cheaper than the classic version of the drug, on average, by fifty rubles.
Reviews about the "Visin" are diverse. Some praise him, saying that with his help it became easier to work at a computer. Especially the effect of the drug appealed to those who are forced to use contact lenses daily. Others did not see a big positive effect. Most often this is noted by people with myopia. They expected improved vision clarity, and the drug is not designed for this. Its purpose is to affect the vessels and moisturize the mucosa. Another disadvantage is the price of the drug. Some respondents consider it high.
Indications for use
Instructions for use for drops "Visin" reports that the drug is effective in the following diseases and conditions:
- Redness of the mucous membranes of the eyes with allergies.
- Swelling and irritation of the mucosa due to conjunctivitis.
- Eye irritation due to contact lenses.
- Redness and swelling of the eye mucosa due to hay fever.
- Swelling of the nasopharyngeal mucosa.
Drops also help a lot (reviews about Vizin confirm this fact) for cosplay lovers and bloggers who often wear colored contact lenses for a long time.
Eye drops "Vizin Pure Tear"
Unlike its predecessor (classic Vizin drops), this drug has a better effect on the mucous membrane of the eye.
"Vizin Pure Tear" is not addictive due to the lack of a clear vasoconstrictor effect. Another point in favor of choosing this particular option is a lower price. Reviews on eye drops "Vizin Pure Tear" are positive. The tool is often used by people who are forced to sit at a computer for a long time, after which the mucous membrane dries and tear increases. Reviews about "Vizin Pure Tear" emphasize that the use of drops quickly and effectively moisturizes the mucous membrane, relieves tension and eye fatigue. At the same time (unlike the classical version of drops), “Pure Tear” is very rarely addictive and provokes subsequent redness of the eyes.
Eye drops "Vizin Alergi"
This option is good because it is ideal for patients with allergies. In late spring and summer, hundreds of thousands of people suffer from tearing from hay fever. Reviews of drops of "Vizin Allergy" confirm the fact that this tool allows patients to lead a normal lifestyle even in such a period. This medicine has also been ideally proven in the treatment of allergic conjunctivitis.
Sold "Vizin Alergi" in a bottle with a dropper of 4 ml of a 0.05% solution. The main active ingredient is levocabastine. The therapeutic effect of the drug begins ten minutes after instillation and lasts about ten hours. It is recommended to instill one drop in each eye before leaving the house. If necessary, you can use the drug twice a day. After the cessation of allergy symptoms, the use of Vizin Alergi should be discontinued.
Feasible side effects
As mentioned above, with the use of the classic Vizin drops, drug addiction can develop, which is expressed in redness of the eyes without the use of vasoconstrictor medications. This condition passes quickly. To do this, for about a week it is worth completely abandoning such drugs. Then the vessels will return to their normal mode of operation.
To prevent addiction, you should completely abandon the use of drops on a daily basis. Even if, for one reason or another, the patient is forced to use the drug every day, after a month you need to take a break for at least two weeks.
Can I use Vizin eye drops for children and adolescents?
Instructions and reviews indicate that the dosage for children from six years is the same as for adults. Drops are used to relieve eye fatigue, as well as the prevention of childhood myopia with a long time at the computer and reading.
Today, many teens use contact lenses, as they are shy about wearing glasses. In such cases, you need a "Visin". The reviews confirm that tens of thousands of teenagers use these drops when wearing colored contact lenses, as well as therapeutic ones with diopters. In both cases, the use of drops allows you to avoid redness of the eyes, moisturize the mucous membrane and relieve tension from the optic nerve.
Terms of use
Here is the Vizin instillation algorithm, following which the patient will not be able to harm himself:
- Before using the drug, wash your hands with soap.
- The vial should be stored in a clean place to prevent harmful bacteria from entering it and the subsequent development of conjunctivitis after using the medicine.
- Remove the cap from the bottle with clean hands, turn it over.
- Tilt your head back so that your chin is facing the ceiling.
- Try not to touch the eyeball during instillation.

Customer reviews about "Vizin"
Hundreds of thousands of patients felt the effects of this drug. There are dozens of reviews about Vizin eye drops, both positive and negative.
Most of all, eye drops liked contact lens wearers. Almost all respondents noted that with the help of the product they got rid of the dryness of the mucous membrane and the feeling of “sand in the eyes”. The lens began to fit better to the eyeball, the eyes became less tired.
But people with severe myopia (myopia over five diopters) were mostly disappointed with the effect of the drug. Many patients expected improvement in vision, although drops did not have this effect. Their goal is primarily to moisturize the mucosa and affect the blood vessels.
Opinion of ophthalmologists
Doctors actively prescribe these eye drops for people with myopia, hyperopia, cataracts and astigmatism, as well as everyone who wears contact lenses. They inform their patients about the advisability of using Vizin to moisturize their mucous membranes. After instillation, the lens adheres better, does not move and does not bring discomfort to the patient.
Often, ophthalmologists, guided by the instructions for use with Vizin (patient reviews confirm this), are advised to take breaks in the use of the product. If you use drops daily for a month, you must definitely take a break at least two weeks. After this, you can again repeat the daily instillation course. Long-term use of "Visin" can lead to the development of glaucoma, so be sure to take breaks.
