The eyes of a person during the day receive a gigantic load. This includes working at a computer, reading documents, and driving a car. For many, even a long-awaited rest in front of the TV significantly increases the load on the organs of vision. A combination of negative factors, together with unfavorable heredity, can contribute to the development of astigmatism. As a result, the visible image becomes blurry and fuzzy due to the fact that some objects are focused in front of the retina, while others are behind it. Negative manifestations can be eliminated with the help of modern corrective agents.

In order to save time and effort, this review presents models of the best toric contact lenses, the use of which improves vision with a significant degree of refractive error. Unfortunately, they do not relieve the problem itself, and only the attending physician determines the methods and methods of treatment.
Content
Astigmatism (lat. - the absence of a point (focus)) is a visual defect caused by an altered shape of the lens or uneven curvature of the cornea of the eye.
As a rule, the lens and cornea of the eye have regular shapes with the same curves in all directions. This ensures the correct focusing of light on the retina, which is located on the fundus.
In the case of uneven or irregular curvature of the cornea/lens, the light rays are refracted incorrectly and refraction occurs. As a result, images are focused either behind the retina or in front of it, and it becomes blurry.

With astigmatism, the degree of change in curvature and shape is taken into account, and not the fact of their presence. Therefore, in a weak degree, with a value of less than 0.5 diopter, it is present in most people and does not require correction, since it does not cause discomfort.
As a result of a violation of focus in the visual organ, the problem is often accompanied by nearsightedness or farsightedness.
The main types are:
1. Simple myopic - a beam of light hits the retina along one meridian, and in front of it along the second.

2. Hyperopic simple - a beam of light along one meridian - on the retina, along the second - behind it.

3. Myopic complex - focusing in front of the retina (myopia).

4. Hypermetropic complex - focusing behind the retina (farsightedness).

5. Mixed - a beam of light along one meridian is focused in front of the retina, along the second - behind it.

The value of the value in diopters is determined by the difference in refraction of the strongest and weakest meridians of the lens or cornea. The direction of the meridians determines the axis of astigmatism. The degrees are:
In the early stages, the problem is often confused with ordinary fatigue, in which:





A throbbing headache is often felt!
In the course of a routine ophthalmological examination, astigmatism is practically not detected, but is taken for manifestations of farsightedness or myopia.
Correct diagnosis requires a detailed analysis of the visual system. For this, autorefractometry, keratometry or keratotopography are used.
Indications for correction are:
An additional load on the cornea is created due to the increased thickness of the toric lenses. Direct contraindications for their use are:
Contact correction is carried out:
The design of a toric lens, unlike the classical one, has a spherical shape, and not a spherical one.Outwardly, it resembles a ball squeezed from below and from above. The toric surface is created either on the back (correction up to 6.0 D) or on the front (up to 4.5 D) surface. As a result, two optical powers are formed, of which one is for correcting astigmatism, and the other is for concomitant pathology.

The corrective effect is only achieved when installed in the exact position. At the same time, the stability of the optical system is provided by special fixation mechanisms.
Self-selection of toric lenses is not possible!
For the correct location in front of the eyes, the following nuances should be considered:
At the same time, the condition of the organs of vision, age, profession and other factors of a person's lifestyle are taken into account.

All selection actions are carried out by a medical officer strictly individually. The ophthalmologist performs computer diagnostics for a detailed study of corneal defects. Then there is a selection of parameters and fitting lenses. The doctor must make sure that they fit correctly in front of the eyes.
Particular attention is paid to the following points:
Popular models of contact toric lenses can be purchased after consultation with an ophthalmologist in specialized medical salons. In each of them, before buying, there is an opportunity to undergo an additional eye test, as well as get useful recommendations from an experienced specialist - which company is better to buy, how to use and store, how much it costs.

If it is impossible to find the right model at the place of residence, suitable products are available for ordering online on the pages of aggregators, such as Yandex.Market, or optics stores. There are product descriptions, main characteristics and parameters, customer reviews, delivery rules.
Assistance in the selection will be provided by the presented rating, which is based on the opinions of users. The popularity of models is due to the presence of positive reviews, functionality, reliability and price.
The review includes ratings among the best contact lenses with a replacement period of one day, two weeks and one month. Unfortunately, after the total sale of the remaining stocks of original models on the Russian market, it is unlikely that worthy products will remain that will provide effective assistance in solving vision problems.
