Contact Lenses for Astigmatism

Astigmatism is a common refractive error that affects the way light enters your eye, causing blurred or distorted vision. It occurs when the cornea (the clear front portion of the eye) or the lens inside the eye has an irregular curvature, resulting in an inability to focus light precisely on the retina.

What Are the Causes and Symptoms of Astigmatism?

The primary causes of astigmatism can be genetic or present from birth. However, it can also develop later in life due to various factors, such as:
 

• Eye injuries or surgeries
• Certain eye diseases, like keratoconus
• Excessive exposure to ultraviolet (UV) radiation
• Excessive eye strain or squinting

The symptoms of astigmatism can vary in severity and may include:
 

• Blurred or distorted vision at all distances
• Headaches or eye strain
• Squinting to improve vision clarity
• Difficulty seeing at night or in low-light conditions

If you experience any of these symptoms, it's crucial to consult an eye care professional for a comprehensive eye examination and proper diagnosis.

Types of Contact Lenses Available for Astigmatism

There are several types of contact lenses available for individuals with astigmatism. Here are some common types of contact lenses for astigmatism:
 

• Toric Contact Lenses: Toric lenses are specifically designed to correct astigmatism. They have different powers in different meridians of the lens to address the uneven curvature of the cornea or lens. Toric lenses are available in both soft and rigid gas permeable (RGP) materials.
• Hybrid Contact Lenses: These lenses combine a rigid gas permeable center with a soft lens skirt, providing the crisp vision of RGP lenses and the comfort of soft lenses. Hybrid lenses can be an excellent option for individuals with astigmatism who may have difficulty adapting to standard RGP lenses.
• Scleral Contact Lenses: Scleral lenses are larger gas permeable lenses that vault over the cornea and rest on the sclera (the white part of the eye). They can effectively correct astigmatism and provide comfort for individuals with irregular corneal shapes.
• Multifocal Toric Contact Lenses: These lenses are designed to correct both astigmatism and presbyopia, a condition that affects near vision as people age. They offer different powers in various zones of the lens to address both conditions.
• Custom Soft Contact Lenses: Some individuals with astigmatism may benefit from custom soft lenses that are tailored to their specific corneal shape and visual needs. These lenses are designed based on detailed measurements and may provide a more precise fit.

It's important to consult with an optometrist, to determine the most suitable type of contact lens for your specific astigmatism correction needs. An optometrist can conduct a comprehensive eye examination and fitting process to ensure the proper selection and fitting of contact lenses for optimal visual correction and comfort.
