Reddened sclera of the eyes is not the most pleasant phenomenon, the cause of which can be lack of sleep, overwork, excessive stress on the organs of vision. Regardless of the cause of this condition, it gives a person a tired, broken look and a lot of discomfort.
Redness of the sclera can look different. In some cases, dilated vessels are visible on the whites of the eyes, while in others the sclera acquires a uniform pink tint (in situations where small capillaries are involved).
Dilatation of blood vessels occurs not only on the so-called protein of the eye, but also on the mucous membrane of the eyelids - they are also hyperemic and look swollen.
This flaw cannot be hidden with makeup. Therefore, special ophthalmic products are a real salvation for owners of tired, reddened eyes. In particular, patients are prescribed the drug "Iridina" - eye drops with a vasoconstrictive effect.
Composition
The active substance is naphazoline hydrochloride. Therefore, any drug that has a similar composition, including the well-known Naphthyzinum, is an analogue. "Iridina" - eye drops, which are positioned as a cosmetic product, but in fact are a pharmaceutical drug. The analogues also include the drug "Polinadim" from a Russian manufacturer.
Operation principle
Redness of the mucous membrane of the eyes and eyelids is associated with the expansion of small blood capillaries, localized in abundance in the structures of the eyeball. The "whitening" effect that the drug "Iridina" (eye drops) has is a consequence of the vasoconstrictive effect of the active ingredient.
Naphazoline, which is the active ingredient in eye drops "Iridina", belongs to the class of alpha-adrenergic agonists. Causing excitation of alpha-adrenergic receptors, naphazoline hydrochloride provides a vasoconstrictor effect. That is why redness disappears from the mucous membrane of the eyes.
Indications for use
- Redness of the mucous membrane of the eyeball.
- Irritation, swelling on the eyelids.
- Discomfort in the form of burning eyes or itching.
- Increased tear production, lacrimation.
- Increased eye sensitivity to light (both daylight and artificial light).
Before you start using this remedy, it is highly advisable to consult an ophthalmologist to clarify the indications and receive recommendations on the optimal regimenuse of the drug "Iridina". Eye drops are considered safe, but improper use can cause adverse reactions. Dosage must be individualized.
Drug "Iridina" (eye drops): instructions for use
Redness Eliminating Drops are recommended to be used before applying eye makeup. 1-2 drops of the product are instilled into the conjunctival cavity of each eye (it is more convenient to do this in the supine position).

Contraindications to the use of Iridine drops
- Increased intraocular pressure regardless of etiology (glaucoma and other ophthalmic hypertension).

Special Instructions
- Vasoconstrictive eye drops should under no circumstances be replaced by similar nasal preparations, since nasal drops may contain auxiliary ingredients that can adversely affect the structures of the organ of vision. In addition, the concentration of the active substance in nasal products is usually higher, which can cause undesirable effects when using such drops as eye drops.
- The use of drops during pregnancy is possible only in case of emergency.
- It should be borne in mind that the effect of vasoconstrictor drugs is not permanent. With prolonged systematic use, tolerance to the effect of the drug develops. You can avoid this development of events by taking breaks in the application of drops every few days (once a week or more).
- To avoid contamination or infection of the contents of the vial, it is necessary to prevent contact of the tip of the vial with the surface of the mucous membrane of the eye during instillation.
- It is necessary to remember which group "Iridina" belongs to. Eye drops, positioned as a cosmetic product, contain a vasoconstrictor component. In order to avoid the development of side effects from the systematic use of this remedy, one should refrain.
- If there are anyophthalmic diseases, Iridina eye drops can be used only after consultation and approval of an ophthalmologist. The doctor will be able to draw up a suitable treatment regimen.
- If undesirable side effects or other unusual symptoms appear during therapy, it is necessary to stop using Iridina eye drops. Reviews indicate that side effects occur infrequently, but this situation requires specialist advice.
In no case should you self-medicate. Remember that the wrong use of medicines can only aggravate the situation.
