People who wear contact lenses do so for four reasons, namely:

• To look better aesthetically.
• Because they are more comfortable than glasses.
• Correct visual refraction defects.
• To improve your visual field.

Contact Lenses for Astigmatism

Astigmatism is a refractive error in which there are different powers in the different meridians of both the cornea and the lens. As a result of this, an image is not formed on top of the point retina, but two lines separated from each other, causing vision to become cloudy, no matter how close or distant the object being viewed is.

To compensate for this ametropia, the use of special glasses or contact lenses is recommended.

Characteristics of Contact lenses for astigmatism

Now, there are some lenses designed especially for astigmatism, these are also known as toric, They have some very particular characteristics, among which we can highlight:

• Unlike other types of contact lenses, these have more than one curve in their design.
• The placement of the lenses must be done following the instructions given by the vision professional to the letter, otherwise the person may begin to suffer visual discomfort and complications.
• After the lens has been placed in each eye, it is essential to avoid turning, to have a clear vision
• There are lenses designed to compensate both astigmatism along with myopia/hyperopia, as well as presbyopia.

For all these reasons, the costs of contact lenses for astigmatism usually increase considerably, since they are designed to meet the needs of each user, that is, there is no standard model.

Types of astigmatism

Astigmatism can be accompanied by nearsightedness or farsightedness, and also remains when presbyopia appears.

In this sense, according to the set of complications that the individual has, astigmatism can be located in one of the following categories:

• Simple astigmatism: in this only one axis is affected, the other focuses on the retina.
• Simple myopic astigmatism: the affected axis focuses in front of the retina.
• Simple hypermetropic astigmatism: the affected axis focuses behind the retina.
• Compound astigmatism: it is always associated with myopia or hyperopia, neither of the two axes is located above the retina. It includes mixed astigmatism, which is when one axis is in front of the retina and the other behind.
• It should be noted that this is no longer a cause for concern because technological and scientific advances have made it possible to manufacture lenses that allow these visual defects to be compensated for at the same time.

The fore going reveals the need to wear contact lenses expressly recommended by the ophthalmologist or optometrist, since these specialists are in charge of carrying out the corresponding studies to determine what type of deficiency the patient presents and, consequently, suggest the ones that are suitable for each case. even if the graduations on the left and right eye are not the same.
