A Closer Look At Toric Contact Lenses

Contact lenses quickly established themselves a valuable product to people with vision problems once they released to the public. Since then, a number of advancements have been made so the contact lenses can be worn by people with specific eye related conditions. Toric contact lenses are one such solution that has proven invaluable. They were created to help people who suffer from having an astigmatism as regular contact lenses because traditional contact lenses simply couldn’t be worn. While they continue to become more well known, many people still have questions about toric lenses. Here is a closer look at what they are and how they can help.

If a person has an astigmatism, then their eyes must use special contact lenses that are designed to compensate for the irregular shape of the cornea. Toric contact lenses are the solution to this problem. They are often made from a water-based gel-like material that allows them to be both comfortable and flexible, while still ensuring better vision. The reason that using soft contact lenses is that they allow the surface of your eye to get oxygen. The gel-like material allows oxygen to pass through the lens and directly to the eye. As an added bonus, toric contact lenses can also correct nearsightedness and/or farsightedness at the same time that they address the astigmatism.

The primary difference is that regular contact lenses are designed to fit to the natural curvature of the eye. However, people that have an astigmatism do not have a normal curvature, which is where toric lenses come in. Aside from their design, they function the exact same. However, it is important to note that because toric lenses are designed differently, there are some big differences between them and traditional contact lenses. One of the most glaring differences is that they are constructed in a much different way. Because there are a variety of different power combinations, a toric lens must be custom fit to your eye. This means that before ordering these lenses, the correct fit must be found. This means that toric lenses are often more expensive than traditional lenses. It also means that you cannot simply stop by your optometrists and get some new contacts. They will most likely need to be specially ordered and will take a few days to receive them (so plan ahead).

If these types of lenses are not for you, there are other similar options available as well. Sometimes a regular lens is enough to “mask” the astigmatism, however this is only the case if your astigmatism is relatively minor. There are also smaller, more rigid contact lenses that can be an alternative to toric lenses. They are easier to take care of and often last much longer. However, they are also more expensive and will often be uncomfortable for several weeks before your eyes get used to them.

Hopefully this has helped you to better understand toric contact lenses, what they are, what they do, and why they have become popular. However, if you are looking for an alternative type of contact lenses to deal with your astigmatism, make sure to visit your optometrist and talk to them about what other options would likely be the best fit.

How Toric Contact Lenses Can Benefit You

There are many types of contact lenses available now days and sometimes it is hard to know exactly which ones to select. Many people who where contact lenses generally find one brand and one type of contact lens and stay loyal to it. This is due to the comfort level of the band and lens.  If you have an astigmatism then you would want to get a Toric contact lens. The Toric lens were created to correct the condition call astigmatism, which occurs when your cornea is shaped in a oval type shape versus the traditional round cornea.

Toric contact lenses correct an abnormal cornea or lens curvature. The curvature correction makes light rays, that previously bent and produced an unfocused image, focus on one point at retina. This causes the vision to stay identical whether it is positioned as inserted in the eye, or if it rotates to any other position in the eye.

Specialist have been working on Astigmatism to correct contacts in order to have clear vision or the sight will stay fuzzy and not crisp. Several years ago the only correction for this condition was through wearing glasses to adjust out the vision. Toric contacts were invented for this purpose. Toric contact lenses are designed with two prescriptions of sight in them and have to stay in one position for the wearer to see appropriately. The contact lenses contain a thicker bottom or weight in them so that they maintain the same position and do not turn with the consumer’s eyes.

There are several types of toric lenses that you are able to select from. You can wear soft toric contact lenses or gas perm toric contact lenses. With a soft toric contacts, the contact lens is designed specifically to orientate itself on the eye. Once you place on your toric lens, it may take a few seconds of blinking for the lens to line up and adjust properly. After a few seconds, your vision will correct and should be clear with great comfort.

Gas permeable toric lenses work a little different than soft contact lens. They are made in many different designs based on the refraction and shape of the cornea. While gas toric lenses need to be properly fitted, they provide superior optics along with crisp consistent vision for the consumer. There are also toric contact lenses designed for Multifocal and Bifocal consumer needs.  As you enter and move through your forties, chances are toric bifocal contact lenses will meet your eye needs.

While glasses are designed to correct single vision’s with bifocal and trifocals a multifocal toric contact lenses correct all distances in one lens. The lenses are manufactured with the principle that when a person looks down to read something up close, the pupil sees through the center of the contact lens.  While looking out to further distances, the pupil will look through a range further out on the contact. With this concept, all vision at any range is always in focus with a multifocal which is a technological advance in eye care.
