Contact lenses toric: selection. User Reviews

Not everyone wears the same type of contact lens. And it's not just about color or one-day. So, for example, sometimes you need special contact-toric lenses. This is associated with a disease such as astigmatism. We suggest you to understand what toric contact lenses mean, their selection and features of wearing.

What is astigmatism?

Astigmatism is a condition where the cornea or lens has an irregular shape, resulting in light being refracted differently and the image being blurred.

To determine the degree of disease, it is necessary to identify the degree of meridians through which the rays of light pass. The scale varies from zero to one hundred and eighty degrees.

The causes of the appearance of astigmatism can not be established accurately. It can be innate or manifest with time.

If you do not take any measures, then astigmatism will develop and may be accompanied by such unpleasant things as:

• strabismus;
• Frequent headaches;
• Itching and cutting sensation in the eyes.

It is treated by the following method:

• Wearing special glasses;
• Orthokeratology;
• Laser surgery;
• Wearing toric lenses.

Toric lenses

All these special lenses are made of the same material as the simple ones, which are called spherical. So then, what does toric contact lens mean? The fact is that they consist of two optical forces whose curvature is at different angles. One is needed to correct astigmatism, the other - myopia or hyperopia. They are arranged in such a way that the lens does not move from the cornea during blinking or eye movement. That is, if the spherical lens can move freely along the cornea, then for the toric lens this is unacceptable. They must be fixed on the eye.

Contact toric lenses come in the following types:

• Soft or hard;
• One-day or prolonged wearing;
• Colored.

Doctors recommend wearing toric lenses only to patients with astigmatism, but also with such diseases as:

• cataract;
• Diseases and injuries of the cornea.

The appearance of toric lenses is a combined spherical and cylindrical shape.

The composition of the lens is divided into hydrogel and silicone hydrogel. The main difference is the way air is passed: through water or a silicone component.

Lenses daily and one-day

Daily contact toric lenses are the cheapest option. They need to be removed every night and put in a container with a special solution, in which they will be disinfected. Still need to adhere to the schedule of planned replacement. The wearing time varies depending on the type and brand - from two weeks to three months.

One-day toric contact lenses are changed every day. They are worth more, because you always need a new pair. But these lenses are good because they do not accumulate biological deposits and there is no constant need for their disinfection.

Soft and hard lenses

Rigid contact toric lenses are also called gas permeable. All because they are made of special polymers that have high oxygen conductivity.

Their advantage lies in the fact that they keep the shape very well on the eye. Sometimes doctors advise putting on such lenses at night, and in the morning taking pictures. During this time they act on the cornea, that it becomes a little flat. As a result, the curvature around increases and the vision becomes clearer. This effect persists throughout the day.

Soft toric contact lenses are a relative novelty in the market. They are also gas permeable, as well as rigid, but differ in their structure. Soft lenses - this is a thin film, in which one wall exactly repeats the shape of the cornea.

They are suitable for daily wear, but need constant cleaning and moisturizing. The main advantage of soft lenses over rigid ones is the absence of a period of habituation and adaptation.

Color contact lenses

Are there toric colored contact lenses? The answer is yes, there are. Only not all types have a wide color palette. So, for example, some one-day toric colored contact lenses are only in some shades, and long wearing - others.

Now new color lenses of Korean and Chinese production appear on the market. They are much inferior in quality to special toric, but they have a wide palette. Such lenses are suitable only for undue wearing (no more than six to eight hours).

Toric contact lenses: selection

The choice of any lens is based on individual needs and features of vision. The same rule applies to toric lenses.

The main criteria that influence the choice:

1. Will you sleep in the lenses?
2. Do you need lenses to wear all day or from time to time?
3. What kind of lifestyle do you lead?
4. Your age.

If you can answer these questions on your own, then to make the lens not bring discomfort and raise the level of vision, it is necessary to conduct a number of tests with the oculist. This is the main difficulty in wearing toric lenses. As a rule, ophthalmologists perform measurements of all data with the help of modern computer equipment:

• Refraction (visual acuity);
• The condition of the cornea;
• Degrees of deviation of the meridian.

In some cases, doctors give the patient a trial set of toric lenses.

After the ophthalmologist has prescribed a prescription for you, you can from time to time buy contact lenses on your own (in optics or online stores). But after a while you will need to contact the doctor again. You may need to correct the data.

Cost of lenses

Prices for a ruler of toric contact lenses are higher than for simple spherical ones. This is due to their specificity.

Also, such lenses are more expensive than special glasses. But the high cost is justified by such advantages as high visual acuity and convenience.

As for the price inside the line, the cost of silicone hydrogel will be slightly higher than hydrogel.

Toric contact lenses: reviews

The main points that people who wear toric lenses notice:

1. For allergy sufferers and people with sensitive eyes, one-day contact lenses are the most appropriate option.
2. Toric lenses have a big advantage over the glasses. The picture is more clear and there are no limitations of the field of view.
3. Rigid lenses are better fixed and retain their shape, but when a speck of dust or mote comes in the eye, very much discomfort is felt.
4. Soft toric lenses are more convenient and comfortable, but they do not provide high-definition vision.
5. Always with yourself you need to have moisturizing drops. When the lens dries up, there is discomfort in the eye and visual acuity decreases.
6. It is much more convenient to wear lenses than glasses.
7. For convenience, it is better to have several types of lenses. For example, one-day and prolonged wearing.
8. The worse the vision, the thicker the lens. In this regard, there is often discomfort.
9. After prolonged wearing of toric lenses, astigmatism of the cornea is slightly corrected.
10. Toric lenses fit even children who often do not like to wear glasses.
11. Thanks toric lenses there are no changes in the style of life. For example, everyone can also actively engage in sports.

It is worth remembering that all reviews are based only on personal feelings of patients. Therefore, one can not critically adjust to any particular type of toric lens. Perhaps, you will approach the species, which in others causes irritation and discomfort.
