Have you decided it is time to put your glasses in a case and try out the benefits of contact lenses? You do not want to put your glasses off completely, but are you looking for a suitable alternative that allows you to actively perform all kinds of activities without restrictions? Then you will probably be interested in what contact lenses are available on the market. Although at first glance almost all look the same (with the exception of colored lenses), there are actually differences between them. Closer familiarization with the character of individual contact lenses can help you in choosing the most suitable for your needs.

Have you been using contact lenses for a long time or are you going to wear them soon? Then you might want to know what the optical specialist must define for choosing the most suitable lenses for your eyes. When issuing a prescription, it is necessary to specify the parameters of the contact lenses on the basis of which the optimal lenses are subsequently selected. Since each person has different eyes, it is important to ensure a comfortable fit.

Causes of hyperopia

As with myopia, the cause of the defect is due to incorrect shape of the eyeball. This is shorter than the ideal curvature. As a result, light rays fall behind the retina instead of directly onto its surface, making the captured image appear blurry. Persons with this disorder often have reading difficulties.

Causes of myopia

Myopia is due to an incorrect shape of the eyeball that is too elongated from the front to the back due to the focusing force of the cornea and lens, or because the cornea or lens (or both of these parts of the eye) are too thick or too curved along the entire length. As a result, light rays in front of the retina fall directly onto the surface of the retina. This makes distant objects appear blurry. This can cause problems in a number of activities such as face, object or distance recognition, sports, driving, and the like. Children whose one or both parents are also short-sighted are at increased risk of this disorder.
