Astigmatism is an eye problem that is related to the irregular shape of the cornea. The shape of the cornea, in this condition, is somewhat like that of the back of a spoon, and as a result, light rays fall on two different points of the cornea instead of one center point, thus causing blurred vision. Even trauma or injury may bring about a similar condition. This condition makes the vision slightly blurred, which is often unnoticeable at first.
Besides adults, even children can be affected by this condition. A few tests that help determine this disorder includes the astigmatism dial, a visual activity test, and tests involving the use of medical instruments such as, keratometer and keratoscope. After diagnosis, the two options of treating this problem are wearing vision correction glasses or contact lenses. People with astigmatism were earlier recommended against the use of soft contact lenses, as they may take the shape of the abnormal cornea without correcting it due to their soft texture. People affected by astigmatism were recommended gas permeable rigid contact lenses that stay in shape and correct this vision defect.
Colored Lenses for Astigmatism
Advancements have been made in the field of contact lenses. Earlier, people didn't even have the option of using normal contact lenses to correct their astigmatism, leave alone colored lens. Today, toric lenses are supposed to be the best suited for astigmatic eyes. These lenses are made from the same material as regular contacts, but they have a different shape. They are very effective as far as vision correction is concerned, and they are readily available as well.
Toric lenses are suitable for people affected by astigmatism. Various types of color contacts are available in market. These include hard, soft, multi-focal, bifocal, and disposable contact lenses. These lenses are also useful for the people diagnosed with hyperopia or myopia. These lenses do not rotate inside the eyes. The few brands that offer the best colored contacts are Freshlook, PureVision, and Acuvue.
Due to the nature of the colored lenses that fit astigmatic eyes, you will be expected to pay more than the price of a normal eye lens, as much as 25-30% more. Besides toric lenses, the other option is gas permeable lens that are rigid and keep the lens in place, though nowadays you do get soft contact lenses too that are designed specifically for this condition. Gas permeable lenses are great because they allow the cornea to breathe, which is really important for eyes.
Other than that, there are three definitive kinds of tints available when it comes to color contacts for astigmatic eyes:
These kinds of color tints are solid but translucent at the same time. These come in dark shades and do not change with the color of the eyes. Enhancement tint color contacts are best for people with light colored eyes and also for people who want a more intense eye color.
Visibility tint color lenses for astigmatism come with a hint of several light eye color shades added to them. Light blue and light green being favorites, visibility tint contacts are better for removal and insertion of the lenses as they are visible to astigmatic eyes too.
These are basically deeper color tints that help to change the eye color with another suitable solid eye color. Most popular amongst them being green, blue, hazel, honey, violet, amethyst, gray, and brown.
Two things to consider are:
- Choose the best color that suits your skin
- Don't buy contact lenses without prescription.
Your eyes are one of the most precious parts of your body, treat them well and don't try to abuse them by experimenting with contacts that you're not sure of. Obtain a prescription from a registered optometrist and then purchase colored contact lenses for your astigmatic eyes only from a known brand such as Freshlook, Acuvue, or PureVision.
