by If you have ever gotten a contact lens and felt like it was a bit uncomfortable, you were probably right. Contact lenses, also called contact lenses, are extremely thin artificial lenses placed directly onto the surface of your eyes. They are used by more than 150 million Americans today, and they can either be worn as corrective ophthalmic devices for corrective vision, or for therapeutic or cosmetic reasons. As an alternative to glasses, contact lenses can offer a better vision quality and a more natural image. But not all contact lenses work the same way. Here are some things to know about your contact lens to ensure a great experience with your contact lenses.
Every contact lens is made up of a polysulfone wafer along with a layer of a protein coating. The protein coating protects the wafer from abrasion and helps to smooth out rough surfaces. Once the contact lens is applied to your eye, the wafer is shaped to fit perfectly onto the cornea. This layer also helps to stop foreign objects from scratching your eye, which could cause irritation, infections or damage to the cornea. Once this layer is in place, the contact lens is ready to be worn.
One of the most important parts of contact lens usage is making sure you get the proper size. Most people need to purchase either soft contact lenses or extended wear lenses to be comfortable. Most contact lens companies offer a free trial to their soft contact lenses. This will allow you to try them on at home to see if you have vision problems with them before purchasing extended wear lenses.
Wearing contact lenses that are too small for your eye can cause issues such as headaches, fatigue and pain. Wearing contact lens too long can result in thinning of the cornea and irritated eyes. A good rule of thumb is to start out with softer lenses and increase the size of them as your eyes become better. Some contact lens producers even offer disposable contact lenses. These are basically used once and then discarded.
Contact lenses come in two basic styles – soft contacts and rigid gas permeable (RGP) contact lenses. Both styles are used to correct a specific vision problem. Soft contacts are thinner than rigid gas permeable contacts. This means they are more often made out of silicone, which is also less likely to irritate the eye. If you suffer from astigmatism, you may want to consider soft contact lenses. Astigmatism occurs when there is a very close focus on your cornea, resulting in blurry vision.
RGP contact lenses are usually preferred by those who don’t have astigmatism. They are often made out of carbon fiber or polycarbonate. The lens is actually pushed through the eye rather than held in place by the cornea like the soft contacts are. Because of this, there is less pressure on the cornea and it provides clearer vision for most people. On the downside, they are more expensive and can be hard to find.
If you are looking for the perfect solution, consider soft contact lenses. They work just as well as rigid gas permeable lenses, if not better. They fit your eye much nicer than RGP, and if you spend enough time stretching them, you can actually reduce the size of your cornea. This will allow you to get more distance between your vision centers, making your vision clearer at the same time. The best part is that they are a lot less expensive than RGP contact lenses. You can even get discount contact lenses if you are an avid sportsman or other person who plays very close to the ground.
Take some time to learn more about contact lenses, whether you are a sportsman a hunter, or just someone who likes to look great. There are soft contacts to suit every situation and every person. Consider the benefits, disadvantages, and benefits of each type of contact before making your final decision. Who knows, you may find that the perfect solution lies within the fuzzy lines of soft contact lenses.
