First of all, find out why: perhaps it is astigmatism.

Our eyes are very tired, causes and explanations for this - a lot. Sitting at the computer, to multitask, nervous in traffic jams. "The head swells!" - We say, and trying to escape, open Internet, which again engages our vision. It is particularly difficult for people with astigmatism.

According to the statistics: astigmatism is present in every fourth inhabitant of the earth. It's nearly two billion people! In this case, a small degree of astigmatism, people often do not notice. Getting used to see everything in a slightly distorted form, and not unaware of the existing problems with vision.

Feature, not a disease

Astigmatism, contrary to popular belief, not a disease, and impaired vision.

See objects at any distance slightly blurred or distorted - stretched vertically or horizontally. This is because the light rays passing through the eye, do not focus at a single point. To light beams focused at one point, the eye must have perfect regular spherical surface. However, in nature is absolutely correct forms are not found, which means that some people have the shape of the cornea more round (spherical), while others - oval (aspherical), and the more oval shape has a cornea, the more pronounced astigmatism.

In everyday life, astigmatism can deliver tangible human discomfort, since reading and ending near the recognition of objects in the distance. This is true even if the person uses conventional means vision correction - spherical glasses or spherical contact lenses, which do not correct astigmatism. No special glasses or contact lenses leads to the fact that when reading in people with astigmatism have to constantly hard to strain to focus on the elements of the letters that have both horizontal and vertical lines.

Due to the constant voltage eyes get tired quickly, there may be a feeling of pressure on the eye, eye pain and headache. Therefore, if the reading or working at the computer your eyes tire quickly, and you often experience headaches, check eyesight!

In addition, people with astigmatism see worse in low light, such as at dusk or at night, they can be broken stereoscopic vision and reduces the ability to distinguish colors. If you are a driver, be sure to think about it!

Correct focus: toric contact lenses

Astigmatism should be corrected, even if its degree is small. In addition to a clear vision, astigmatism correction prevents headaches caused by eye strain, reduces the risk of inflammation of the eyelid margins (blepharitis) and improves the quality of vision, especially at night.

Corrected vision with astigmatism simply with the help of special glasses or toric contact lenses, preferably one-day or two-week.

Unlike toric contact lenses from spherical usual - in a special design. Such a lens does not rotate on the eye, or vision will be blurred. The design allows rapid stabilization of the lens to remain in the correct position on the eye, besides any rotations or inclinations of the head or body is not affected by its position, it is always in the correct position. A clear vision is provided regardless of what the person is engaged - working at the computer, riding a bike or watching TV while lying on the couch. In addition, toric contact lenses have unique properties that give a feeling of comfort and freshness all day long.

Wearing lenses or glasses? On this question, each person with visual impairment is responsible to himself. In the case of astigmatism in contact lens vision correction has several significant advantages over glasses.

* If you wear contact lenses, unlike glasses, the sizes of objects are not changed (plus-points of their increase, and minus, on the contrary decrease).

* Contact lenses do not distort space and distance between objects. In addition, with a high degree of astigmatism glasses can be transported bad: the patient may hurt your eyes and feel dizzy.

* Toric contact provide a better overview of the peripheral compared with the glasses, which is particularly important when driving a car.

* Toric contact lenses are perfectly moisturized, they provide a flow of almost 100% oxygen to the eye and are equipped with a UV filter in its class to protect the eyes from harmful solar radiation.

It is important to remember that the vision of each person individually, and for the choice of suitable contact lenses need to consult a doctor, an ophthalmologist in Salon Optics. Only a specialist can accurately determine the presence and degree of astigmatism, as well as select the right kind of correction.
