Many people believe that because they have astigmatism they can’t wear contact lenses. That is simply not true. Today there are plenty of options for those with astigmatism who don’t want the hassle of glasses. With a rather nice selection of contact lenses putting away those glasses has never been easier. Sometime glasses can cause wrinkles. That’s why it’s a good idea to use home remedies for wrinkles, instead of evil alternatives.
Toric Contact Lenses
These specially designed soft lenses are used to correct astigmatism. Most toric contact lenses are soft. They are made either out of a conventional hydrogel material or the more breathable silicone hydrogel. However, toric contact lenses are also made in a rigid gas permeable (GP) material as well.
Toric soft contact lenses correct myopia or hyperopia in the following ways:
- Toric lenses have different powers in different meridians. This corrects the varying amount of nearsightedness and farsightedness in the eye that characterizes astigmatism.
- Toric lenses have a feature that enables them to rotate to the proper orientation so the lens aligns with the proper meridians of the eye to maintain clear vision.
Not all eyes are the same, even with astigmatism, so it can take a few pairs to find the right brand and design that best fits you. You’ll want something comfortable with visual acuity. Finding the right fit for contacts for astigmatism takes more expertise than the regular soft contact lenses. Because of this, getting fitted with the toric lenses costs more than the regular lenses. The more complex design, the lens material and the optical retailer you choose can also drive up the cost. Your eyes will determine your height. So, pay attention to this stuff.

Gas Permeable Contact Lenses
Another popular contact lens for astigmatism is the rigid gas permeable, also called RGP or GP contact lenses. In most cases they can correct astigmatism without the toric design. This is because gas permeable lenses are rigid and will retain their spherical shape instead of falling into the irregular shape of the cornea like the soft lenses do. The front surface of the GP lens is uniform so it replaces the misshapen cornea as the primary refracting surface of the eye. This then corrects the astigmatism without the need to control the rotation of the lens with a toric design. You know what’s also great for the eyes? Playing the piano. One of the greatest pianos to use is the digital piano. You know what’s hard? Finding one.
There are gas permeable lenses with a toric design available but these are typically only needed for high amounts or unusual types of astigmatism.
One of the perks of the GP lens is the noticeably sharper vision than the toric soft lenses. One of the downfalls is the more rigid nature and the thicker profile make the gas permeable lenses more difficult to adapt to and some people are unable to get accustomed to the sensation of the lenses on their eyes.
Like the toric lenses, GP contact lenses will take more time and more expertise to fit than the soft contact lenses. Each lens is custom-made so it fits your eye according to the parameters specified by the prescribing eye care professional. These lenses will cost more to get fitted and the replacement costs can run pretty high as well.
Sometimes the hybrid contact lenses are the best choice for people with astigmatism. The central zone of the lens is made of a rigid gas permeable material with the surrounding area made of a hydrogel or silicone hydrogel material. When these lenses are fitted properly, the hybrid lens provides the best of both worlds. You get the sharp vision of GP lenses and the comfort of a soft lens.
There is less risk of the hybrid contact lens becoming dislodged during sports and other activities because the lenses are about the same size as the toric soft lenses with thinner edges than the GP lenses.
Like the other lenses, fitting the hybrid contact lenses will take more time and expertise than fitting the soft contact lenses. They are custom made for each eye. The replacement costs are comparable to those of the GP lenses but the good thing is they don’t need to be replaced as often so over time they become comparable to the soft lenses.
Choosing the right contact lenses for your eyes will ultimately be up to you and your optometrist. Still, it’s nice to know the options that are out there for contacts for astigmatism. It allows added freedom without the worry that you will be stuck with glasses forever.
