Astigmatism is a common vision condition that occurs when the cornea or lens of the eye has an irregular shape. This imperfection prevents light from focusing properly on the retina, leading to blurred or distorted vision at all distances.

Causes of Astigmatism

Astigmatism is usually present from birth and may be hereditary. It occurs when the cornea has an oval shape instead of being perfectly round. Other causes include eye injuries, surgeries, or diseases that alter the cornea’s structure.

Common Symptoms of Astigmatism

People with astigmatism often experience blurred or distorted vision, eye strain, headaches, difficulty seeing at night, and frequent squinting. These symptoms can vary in intensity depending on the severity of the condition.

Types of Astigmatism

Astigmatism is classified into two main types: corneal astigmatism, caused by an irregularly shaped cornea, and lenticular astigmatism, which results from an irregularly shaped lens inside the eye. Both types can affect vision clarity.

How Astigmatism is Diagnosed

An eye doctor can diagnose astigmatism through a comprehensive eye exam, which includes tests like the visual acuity test, keratometry, and refraction assessment. These tests help determine the degree and type of astigmatism present.

Treatment Options for Astigmatism

The most common treatments include eyeglasses and contact lenses, which correct the way light enters the eye. For more permanent correction, procedures like LASIK and PRK surgery reshape the cornea to improve vision.

Can Astigmatism Worsen Over Time?

Astigmatism can change over time due to aging, eye strain, or medical conditions. Regular eye check-ups are important to monitor any changes and adjust prescriptions as needed.

Living with Astigmatism: Tips for Better Vision

To manage astigmatism effectively, ensure you have the right prescription lenses, take regular screen breaks, maintain good lighting, and visit an eye doctor annually. Simple habits can help reduce discomfort and enhance vision quality.

Final Thoughts on Astigmatism

Astigmatism is a manageable condition with the right diagnosis and treatment. Whether through corrective lenses or surgery, individuals can achieve clearer vision and improve their overall eye health. Regular eye exams are key to detecting and addressing astigmatism effectively.
