Toric lenses are lenses specially created to correct astigmatism, myopia and hyperopia. Nearsightedness is a vision disorder that makes it difficult for people who suffer from it to focus their vision on points far away from them. Hyperopia is another vision disorder, unlike myopia, which makes it difficult to see up close without interfering with distance vision. Finally, astigmatism gives rise to vision problems in the peripheral field. These three problems are a plague, which can be corrected with toric lenses.

Toric lenses are similar to standard lenses in every way: they can last for several days in a row, in the first place, if you remove them at night and put them in lens solution. In addition, it is better to handle them with clean hands, in order to avoid any risk of infection. The main difference is that these same standard lenses can usually only correct one problem, so in the event of multiple problems, the other concerns remain uncorrected and visual acuity does not become efficient. As with astigmatism, there are two surfaces in the eye each requiring a different correction, in all cases it is necessary to use toric lenses to correct this problem.

Unlike a standard lens, the toric lens has a direction in which it must be placed since its two different correction surfaces must correspond to the areas of the eye to be corrected, so it is even more inadvisable when you wear these lenses to rub your eyes, otherwise you will only shift the correction surfaces in the worst case, and the lens will slide along your eyes, forcing you to remove them, which may be less convenient, to be able to put them back in the right places. Note that some of these lenses are weighted down to avoid excess movement or rotation.

Toric daily lenses to correct astigmatism

A curvature of the cornea, also known as astigmatism, causes those affected to perceive their surroundings as blurred, regardless of the distance. A slight curvature of the cornea is usually not noticed at all, whereas a stronger curvature of the cornea must be corrected with visual aids. Either glasses or toric contact lenses can be used for this purpose. Toric contact lenses offer the great advantage that they preserve the natural appearance and allow maximum freedom of movement. At LensOnEyes you get both toric monthly lenses and toric daily lenses.

Toric lenses are the ideal solution for those who have astigmatism. This is a very common ametropia and you have surely heard of it many times. But what is it exactly? To put it simply, astigmatism is ametropia caused by having different curvatures in the cornea or lens.

What is astigmatism?

Astigmatism is an ametropia where the cornea or lens has an irregular shape with different curvatures in different axes. The corneas of people with astigmatism are usually oblong in shape, like that of a rugby ball. Therefore, the light is scattered on the retina and does not come to focus on a point. This creates a refractive error that distorts light as it enters the eyes. As a result, images look blurry. This ametropia affects both children and adults, which is reflected in difficulties in reading a text or in seeing details both from afar and up close.

Astigmatism is quite common in the population, approximately 30% of the population suffers from it, and, in addition, it can appear combined with myopia or hyperopia.

Causes of astigmatism

The causes of astigmatism can be different but the most normal is that its origin is hereditary, although sometimes it can be triggered by trauma to the eye or pathology. Astigmatism often occurs at an early age, so it is important to detect it and take the little ones to a specialist for an eye check-up.

Whether your astigmatism is slight or not, you will need some type of correction to be able to see clearly. Fortunately, most types of astigmatism can be corrected easily and with the help of toric lenses.

Types of astigmatism

If you have problems seeing clearly both near and far or have frequent headaches, it is advisable to go to a professional and make sure that it is astigmatism, since it will be a professional who will prescribe you toric lenses. Especially after reading, you may experience eyestrain, red eyes, itchiness, and difficulty switching from far vision to near vision and vice versa. With some quick tests, the specialist will be able to know if you suffer from this ametropia and will indicate the steps you have to take to compensate your vision.

Myopic astigmatism

One or both meridians of the eye focus as myopic.

Hyperopic astigmatism

One or both meridians focus as farsighted.

Mixed astigmatism

One meridian focuses as myopic and the other as hyperopic. It can also be classified as regular or irregular. In regular astigmatism, which is the most common, the meridians form an angle of 90 degrees with each other, on the contrary, in irregular astigmatism the meridians are not perpendicular to each other.

There are many other types of astigmatism classifications.

Toric lenses for Astigmatism

Another name by which lenses for astigmatism are known in the optical market are toric lenses , specially designed to correct the different curvatures of the eye. While standard contact lenses have a spherical surface, toric lenses for astigmatism allow us to offer different refractive powers in the respective orientations of our axes, usually perpendicular to each other, facilitating the correction of this specific peculiarity of astigmatism.

Toric lenses correct astigmatism, therefore, they have a thicker area at the bottom to stabilize the lenses and prevent them from rotating in the eye. They are designed so that the lens does not rotate when blinking so that the eye can have a clear vision. There are various brands and materials, available in both daily and monthly lenses.

Toric lenses will be prescribed to you by an eye specialist, it is not up to you whether you need them or not. You can nevertheless discuss your desire and your reasons for wanting to start using them, so that you can discuss them with your ophthalmologist.

This type of lens is available in two versions: either flexible or rigid and gas permeable. The latter are the ones that stay in place the best, but require a time of adaptation to the eye during which your vision will be even more disturbed. They are also drier, which may not be suitable for all types of eyes, and more fragile than soft lenses, which are already more fragile than normal lenses. So, it is recommended to take extra care when handling them.
