Contact lenses Acuvue for Astigmatism: reviews

Astigmatism - a violation of the shape of the cornea or lens. When the sphere is curved, light on the retina is collected not in one point, but in several. Thus, the outline of the subject is blurred, becoming fuzzy. Patients, even those with normal visual acuity, can not perceive objects clearly.

How to correct astigmatism

When the shape of the cornea is distorted, lenses of cylindrical shape are used. If the light hits the parallel plane of the axis of such a glass, it does not refract. This happens if the rays have a perpendicular direction. This process is regulated by the position of the cylinder axis of the lens.

For many years, patients had only one therapeutic way to correct corneal curvature. He was wearing glasses with special cylindrical glasses.

After the start of the production of contact medical products, patients had more opportunities. Lenses from myopia, they were able to combine with the cylindrical glasses. It was inconvenient and did not solve the issue of switching to contact optics.

Currently, there are lenses that help patients with astigmatism. They can individually adjust the curvature of the cornea, and can additionally correct myopia. These are the lenses Acuvue for Astigmatism.

Selection of correction method

Historically, astigmatism is corrected by the use of glasses. Their selection is a complicated procedure. Glasses are made to order on an individual recipe. The big disadvantage is the limitation of visual fields and motor activity. With significant astigmatism, the period of adaptation to the cylindrical glasses can be accompanied by dizziness, nausea, pain for 2-3 weeks. Therefore, with significant deviations from the norm, it is customary to order several pairs of glasses, gradually increasing the correction.

Contact correction of vision is carried out with the help of hard and soft lenses. The latter are most convenient, and among patients with astigmatism their popularity is steadily growing because of the comfort, latitude of visual coverage and freedom of motor activity.

Lenses shown when the shape of the cornea is irregular, differ from the usual toric( cylindrical) surface. They have additional packaging labeling. An example is contact lenses Acuvue Oasys for Astigmatism. Both surfaces of such optical products are convex and are located at different angles.

As well as glasses, the Acuvue for Astigmatism lenses have the correct prescribed axis of the cylinder. Contact correction methods so thoroughly correct the violations that are comparable with surgical in efficiency, but do not have their side effects.

Varieties of toric lenses

As well as conventional contact lenses, their cylindrical counterparts are divided according to the material of manufacture into:

  • hydrogel;
  • silicone hydrogel.

The first are produced from a polymer base with high hydrophilicity. Toric optical pairs pass oxygen well and retain a high degree of moisturizing of the eye. This is due to the high level of comfort in use. A classic example are the lenses Day Acuvue Moist for Astigmatism.

Silicone hydrogel is made from a special innovative basis. Its unique characteristics make it possible to achieve the best results of oxygen supply and moistening of the eye. Contact lenses Acuvue Oasys for Astigmatism have a modern basis, which allows to increase the time of their application. In this case, this will happen without damage to the eye.

Lens wear time

Acuvue for Astigmatism lenses can also be classified according to the time that they can be used before disposal.

Allocate lenses:

  • one-day;
  • planned replacement.

In the first case, it is clear from the title that the maximum life of the products is 24 hours. Day Acuvue Moist for Astigmatism lenses can be used during this time. They are comfortable to wear and do not require additional care. Disposed of in a day, even if used for this period only 2 hours.

A variety of contact optical material used for the manufacture of lenses for scheduled replacement can be applied for up to a month. During this period it is necessary to carry out special treatment with disinfectants. The Acuvue Oasys for Astigmatism lenses are stored in containers for each eye separately. Containers are also subject to processing.

What are the criteria for choosing lenses for astigmatism?

The choice of contact lenses for the correction of astigmatic disorders is made only by a doctor. The ophthalmologist determines the parameters of the radius of the optical power and the curvature of the lens. It specifies the characteristics of the cylinder and the degree of the lens. Only a combination of the information obtained will help to select the corrective pair.

It is necessary to know that the lenses for each eye are selected individually. A toric cone can only be installed on a product for one organ of vision or for both.

Thanks to the development of technology, the curvature of the cornea can now be corrected by contact methods. All lenses of Acuvue for Astigmatism are precisely held in the right position, do not change it during the day. This was made possible by a unique stabilization system. Thanks to it, the image does not lose its clarity with any change in the position of the body. Lenses allow you to engage in outdoor sports. Contact correction methods reduce the ingress of allergens, dust and irritants into the eye. A clear image when using such lenses can be achieved, regardless of visual acuity.

Features of one-day models

Acuvue Moist for Astigmatism lenses give a full sense of freedom and full-featured clarity of objects. They both improve vision and protect the eye from drying out. By correcting the eyesight, they do not need additional care, they are easy to apply. This saves time and does not require compliance with storage conditions, because of one-time use. Acuvue Moist for Astigmatism lenses provide protection against ultraviolet radiation and drying. Substances that fall on their surface are removed and destroyed with them at the end of each day. They are convenient to take in trips, business trips, holidays. In this case, no care is taken for the lenses, a new pair is used daily, extracted from the sterile package.

Acuvue Oasys for Astigmatism lenses also successfully correct the curvature of the cornea. They have increased smoothness of the newest silicone-hydrogel substrate. Such lenses make a clear image and comfortable use. The developed system of instantaneous stabilization successfully holds the lens in the position necessary for the axis. Therefore, Acuvue Oasys for Astigmatism toric lenses have a shorter adaptation time and better consumer feedback. Their effect is especially noticeable when used in dry air( air conditioning, heating, airplanes, etc.) and prolonged work at the computer.

The Acuvue Oasys for Astigmatism toric lenses provide a smooth glide of the eyelid and an optimum fit with the position of the cylinder axis. A stable, clear picture of the surrounding reality is achieved without deformations and errors. These lenses, thanks to the material used in the production - silicone hydrogel, provide protection from ultraviolet radiation at the highest level.

Astigmatism is a disorder that, if not corrected, can progress and cause strabismus. Choosing any of the above models, you can get a full correction of pathology and visual acuity along with freedom of movement and breadth of vision, as well as protect your health for many years.
