The cause of astigmatic disease is the violation of the sphericity of the cornea, because of which two optical foci appear in the eye. Astigmatism promises a blurred image to a person, which is why doctors advise patients to wear astigmatic lenses, which are much more convenient to use than glasses.
Astigmatic or toric contact lenses are significantly different from other types of lenses, since the surface of the eye is far from ideal, and the drug must be securely attached to the pupil. Therefore, people suffering from astigmatism, afraid to use lenses, thinking that it is uncomfortable and not practical. But this is not so! Medicine has stepped far ahead and today toric lenses have perfect shapes.
One-day lenses
One-day astigmatic lenses are not uncommon in the market. They are convenient because they do not need daily care. In this case, the Toric has a very affordable price. Today, one-day lenses are sold in quantities of 10 pieces or more in one package. For example, Acuvue One Day Moist for Astigmatism lenses are offered in packages of:
- 10 pieces;

- 160 pcs;
- 170 pcs;

You can choose for yourself a small package or, conversely, large for a long period.
Color contact lenses
Color astigmatic lenses are not uncommon in optics stores. But in this case also the requirements to the tori, which your doctor put forward, and in particular the basic curvature of the lens, the size of the axis of the cylinder and so on, are also important.
Color lenses are selected similarly to other types of lenses. When choosing a color, you need to consider your own eye color and consult with a specialist in order to get the desired result at the first try.

This is one of the main conditions for correct removal and putting on of lenses. Next, use a special pair of tweezers to remove the lens from the blaster.
