What Contact Lenses Are Best for Astigmatism?

Astigmatism is a common vision condition that can cause blurred or distorted vision at all distances. It occurs when the cornea or the lens inside the eye has an irregular shape. Instead of being round like a ball, the cornea or lens with astigmatism is shaped more like a football. This irregular shape causes light to be focused unevenly onto the retina, the light-sensitive tissue at the back of the eye, resulting in blurred vision.

Understanding Astigmatism

The causes of astigmatism are not entirely understood. It's believed to be primarily an inherited condition, often present at birth. It can also develop because of an eye injury, disease, or surgery. It's important to note that astigmatism is not caused by reading in poor light or sitting too close to the television, contrary to popular myths.

The symptoms of astigmatism are often quite mild. Many people live with a slight degree of astigmatism without even realizing it. Common symptoms include headaches, eyestrain, squinting, and difficulty driving at night. If you're experiencing any of these symptoms, it's important to book an eye examination as soon as possible.

What Are Scleral Lenses?

Scleral lenses are a type of gas permeable contact lens that vaults over the cornea and rests on the white part of the eye, the sclera. The lens creates a smooth, evenly rounded surface over the cornea, correcting the irregular shape caused by astigmatism. This allows light to be focused evenly onto the retina, providing clear, crisp vision.

Scleral lenses are larger in diameter than traditional contact lenses. The larger size helps the lens to stay in place and provides a wider field of vision. The lens is also filled with a saline solution before insertion, which provides constant hydration to the eye. This can be beneficial for people who suffer from dry eyes, a condition often associated with astigmatism.

One of the unique features of scleral lenses is that they create a reservoir of fluid between the lens and the cornea. This fluid layer compensates for any irregularities in the shape of the cornea, allowing for a more natural and comfortable fit.

The Benefits of Scleral Lenses for Astigmatism

There are many benefits of scleral lenses for people with astigmatism. First, scleral lenses provide superior visual acuity. Because the lenses correct the irregular shape of the cornea, they can provide clearer, sharper vision than glasses or traditional contact lenses. Many people with astigmatism who switch to scleral lenses report a dramatic improvement in their vision.

Scleral lenses are also highly stable. Due to their larger size, they are less likely to move around on the eye or fall out. This can be particularly beneficial for people with astigmatism, who may find that traditional contact lenses do not fit their eyes properly.

In addition, scleral lenses are very comfortable. The fluid-filled reservoir between the lens and the cornea provides a cushioning effect, minimizing any discomfort from the lens resting on the eye. Many people find that they can wear scleral lenses for longer periods of time without experiencing any discomfort.

Are Scleral Lenses the Right Solution for Your Astigmatism?

Astigmatism is a common vision condition, but with the right treatment, it can be effectively managed. Scleral lenses provide several benefits for people with astigmatism, including superior visual acuity, stability, and comfort. It's important to have a comprehensive eye exam and discuss your options with an optometrist. With the right treatment, individuals with astigmatism can enjoy clear, comfortable vision.
