Toric Contact Lenses
Toric contact lenses are eyesight tools worn by people who have astigmatism. Astigmatism is blurred vision that is the result of some type of vision defect, such as a small cornea or a badly-shaped lens that does not help an individual focus on the light at the back of his or her eyes. Astigmatism is even known for its association with both nearsightedness (myopia) and farsightedness (hyperopia). Astigmatism is a condition that exists at birth and even improves or worsens over time.
The toric contact lenses wiki definition states that toric lenses come with two prescriptions embedded within them to help people who either have either one-eye astigmatism or astigmatism in both eyes. Both lenses come with a ten-degree difference in the lenses. Remember that often, astigmatism occurs in individuals whose eyes do not properly reach the light at the back of their eyes. The light never bends straight enough into their eyes to provide them with proper sight.
Toric contact lenses reviews show that toric lenses often do wonders for those who struggle with astigmatism. One patient reported that his CSI Toric lenses are better than any toric lenses he has worn to date. He had a toric lens prescription prior to the CSI that would rip and tear after a few months. The CSI lenses have outlasted the horrible kind he remembers wearing. One patient liked the Durasoft 2 Optifit Toric lenses he received, stating that he had been through every type of toric lens his doctor could prescribe over the years. Another customer remarks that she had dry eyes, but her new prescription toric lenses solve the dry eye problem.
One patient has a pair of Acuvue Oasys Astigmatism contacts that he can wear for 20 hours straight. His former contact lens brand could only be worn for sports or special occasions. Durasoft 2 Optifit lenses were worn by a second individual, who says that his eye drop usage decreased while wearing the Durasoft lenses. The problem with his eyes is that they can never stay moist—they always turn dry, itchy, and irritated. An Acuvue Advance Astigmatism lens patient says that he does not even notice he has contacts on. The contacts do not feel like contacts, and he could go at least five days without taking them out.
One patient wears the ClearSight 1 Day Toric lenses and loves the fact that he does not have to worry about cleaning his contact lenses. He can wear them one day, then throw them out. Lastly, one patient recalls that his contact lenses work great at work. Unlike other contact lenses he had before, his current Avaira Toric lenses do not slip in his eyes while he is on his twelve-hour work shift. Many patients seemed to like their toric lenses because of the comfort in wearing them, the moisture the lenses provide for their eyes, and the fact that their toric lenses can be worn for hours throughout the day—quite like their fashion apparel.
There are four types of toric lenses: (1) gas permeable, (2) soft, (3) hydrogel, and (4) bitoric. Rigid Gas permeable lenses (or RGP) are made in a set shape and remain in that shape when worn. They become comfortable over time, but you will have to adjust to their shape—though they are also made of silicone. Soft toric lenses remain in your eyes as they move. They do not slip with motion. Hydrogel toric lenses contain a great percentage of bound water within them, so as to help prevent the increasing eye irritation that comes with dry eyes. Lastly, bitoric lenses are for patients whose eyesight needs correction on either side of the lens. Bitoric lenses are for those who prescription is 2.00D or worse.
Multifocal toric contact lenses use two different contact lenses and combines them on human eyes. The lenses are called “multifocal” because they have two different focuses: one focuses on nearsightedness (life up close), while the other focuses on farsightedness (distances). In some cases, multifocal toric lenses can be worn today by individuals with astigmatism.
Toric color contacts enhance your eye color and provide an eye color to improve your look while the toric lenses themselves improve your sight. Toric color lenses are not only medically efficient but also fashionable and trendy.
Proclear toric contact lenses come tinted and are worn daily on a monthly basis. Each month, you must change your contact lenses and insert a new pair. These lenses are the only ones that have been approved by the Food and Drug Administration as improving the eyesight of astigmatic individuals.
Toric lenses come in different colors, shapes, sizes, tailored to various astigmatic conditions, and can either provide many focuses at once or one focus throughout. There are different types of lenses, made of various materials (some hydrogen, others silicone, etc.), and numerous others of which cannot be discussed here. Color lenses and other toric lens features demonstrate that toric lenses are no longer forced to be boring and dull apparel to wear out in the world. Now, you can have astigmatism and still be trendy, sporty, up with the latest fashion, and so on. If anything, the multiple kinds of toric contact lenses show the world that fashion does not have to be compromised for medical reasons.
