Astigmatism is a refractive error that affects the way light bends as it passes through the eye. This causes objects to look blurred or distorted. Astigmatism is caused by an irregular curvature of the cornea. The result is that light entering the eye is not focused correctly, which results in vision problems. So wearing contact lenses for astigmatism is one of the solutions that can help you to correct this disorder.
How Do You Correct Astigmatism By Wearing Contact Lenses?
There are two types of astigmatism: regular and irregular. Regular astigmatism can be corrected by wearing contact lenses that have a specific curve to them. Irregular astigmatism cannot be corrected with contact lenses and usually requires surgery.
Three Types Of Contact Lenses For Astigmatism:
Toric Contact Lenses:
Toric contact lenses are specifically designed to correct astigmatism. Astigmatism is a common vision problem that occurs when the eye is not perfectly round. This can cause blurred vision and eyestrain. Toric contact lenses are designed to correct the shape of the eye, which helps to reduce these symptoms.
What To Consider While Choosing Toric Contact Lenses?
There are a few things to consider when choosing toric contact lenses. The most important factor is finding a lens that corrects your vision. In addition, you’ll want to find a lens that is comfortable and fits well.
You should also consider the type of material the lens is made from. Some materials are more breathable than others, which can be important if you have sensitive eyes. You’ll also want to choose a lens that is easy to care for.
Rigid Gas Permeable (Rpg) Contact Lenses:
Rigid Gas Permeable lenses, also known as RPG contact lenses, are a type of contact lens that is often prescribed to people who have astigmatism. They are gas-permeable lenses that are made of a rigid plastic material. This makes them more durable and resistant to tearing than other types of contact lenses.
RPG contact lenses can be made in a variety of different shapes and sizes, which allows them to fit more comfortably on the eye. They also allow more oxygen to reach the eye than other types of contact lenses, which can be helpful for people with astigmatism.
What To Consider While Choosing Rigid Gas Permeable (Rpg) Contact Lenses?
Rigid Gas Permeable (RPG) contact lenses for astigmatism are available in a variety of prescriptions and designs. When choosing RPG contact lenses, there are a few factors to consider:
– The curvature of your eye. RPG contact lenses come in two different curvatures: toric and aspheric. Toric lenses have a more curved design to better match the shape of an astigmatic eye. Aspheric lenses have a flatter design that is less curved.
– Your prescription strength. Your prescription strength will determine the power of the lens and how well it corrects the eye disorder.
Hybrid Contact Lenses:
Hybrid contact lenses are a type of soft contact lens that corrects astigmatism. They work by combining the best features of both gas permeable and soft contact lenses. Hybrid contact lenses are made of two different materials: a soft lens material and a gas permeable lens material.
The soft lens material allows the lens to conform to the shape of your eye, while the gas permeable lens material allows the lens to retain its shape. This combination of materials allows hybrid contact lenses to correct astigmatism while also providing all of the benefits of a soft contact lens.
What To Consider While Choosing Hybrid Contact Lenses?
Hybrid contact lenses for astigmatism have a central optical zone that is used to correct your vision and a surrounding area that is used to correct your astigmatism. The surrounding area is typically made of soft contact lens material, while the central optical zone is made of a harder contact lens material. This combination allows the hybrid contact lens to correct astigmatism.
