Contact Lenses for Astigmatism/ Toric Contact Lenses
Back in the day, people who had astigmatism were left with no choice but to adorn big old glasses. However, with the advancement of technology, there has been a mass introduction of various Contact Lenses solutions for patients with astigmatism. You have various options from soft lenses to “hard” lenses to even a combination of both. But what is the best solution for You?
The only way to truly find an ideal solution for you is to visit a competent Optometrist and get your eyes tested and a proper contact lens fitting done.
However, I will highlight two of the best and highly recommended options around so that you can make a more informed decision when you are about to decide on your purchase.
Solution 1) Rigid Gas Permeable (RGP) lenses
This is the most primitive option of them all. Spherical RGP lenses are relatively stiff lenses which do not conform to the shape of our corneas. So when these RGP lenses are placed on the eye and the lenses are fitted firmly and correctly without excessive movement, the RGP lenses actually become the primary light bender. So the light rays which were initially misdirected by the odd shape of the cornea now fall correctly on the retina. These lenses usually work for low to medium grades of Astigmatism. For higher grades of astigmatism, due to the extensive unevenness of the cornea, these lenses would not form a stable fit. There would simply be too much “rocking” of the lenses on the uneven cornea, causing too much fluctuations of the vision. The patient may then be recommended to try Toric RGP lenses.
However, due to the stiff nature of RGP lenses, it may not be suitable for everyone. Some of the complications related to RGP lenses wear are corneal warpage, corneal abrasion and pain caused by wearing such “hard” lenses on the highly innervated cornea.
Solution 2) Soft Contact lenses for Astigmatism (Toric)
Soft contact lenses are the most common solution prescribed for patients with astigmatism for many obvious reasons. Chiefly, the level of comfort soft lenses offer over the course of a day. Soft lenses conform to the shape of our corneas, eliminating the stiffness/friction related complications with RGP lenses. Soft lenses are able to correct extensive grades of Astigmatism and are easily available for order. Soft lenses have various kinds of lens stabilising mechanisms that offer clear and stable vision throughout the day.
We all wear contact lenses for many hours per day. It is imperative that we wear lenses that are comfortable yet provide good vision. With the various lens options available, the Optometrist will definitely be able to recommend the right soft contact lens solution to correct your astigmatism.
