Astigmatic? Don’t Worry, There Are Contact Lenses For Your Condition

Astigmatism is a condition present in most people but to such a slight degree that it does not usually affect vision or require treatment. The condition is characterized by blurred vision due to the irregular shape of the cornea or the lens, which prevents the proper focus of light on the retina. When the astigmatism is more serious, it requires vision correction through special glasses or contact lenses. People who prefer contact lenses can choose either special soft contacts or gas permeable (GP) contact lenses, the latter being described as the perfect solution by contactlenses.org.

According to the article, virtually all cases of astigmatism are related to the surface of the cornea, that is to say, its irregular shape. GP lenses are particularly effective because their rigidity allows them to mold the tear film into a spherical shape. The result is very good vision as the astigmatism gets corrected. For people with a very high degree of astigmatism, another option is the so-called bi-toric lenses. This GP lens design features a different back surface curve in each meridian, the aim being to achieve a better fit while correcting vision.

When it comes to soft contact lenses, the conventional type does not produce results for astigmatic patients. This is because regular soft lenses follow the shape of the eye. However, there are special soft lenses that can effectively correct astigmatism. They are known as toric lenses and come with a curvature that is built into the front of the lens.
