Astigmatism: Symptoms & Treatment Options

Astigmatism is a common vision condition caused by an irregular curvature of the eye’s cornea or lens. Instead of being perfectly round like a football, the eye’s surface is shaped more like a rugby ball. This irregular shape prevents light from focusing evenly on the retina, resulting in blurred or distorted vision at all distances.

Astigmatism can occur on its own or alongside other common eye conditions such as short-sightedness (myopia) or long-sightedness (hyperopia). It affects people of all ages and often runs in families.

What Are the Symptoms of Astigmatism?

Many people have a mild form of astigmatism without realising it. When symptoms do occur, they may include:

• Blurred or distorted vision.

• Eye strain or discomfort.

• Headaches, particularly after reading or using screens.

• Difficulty seeing clearly at night, especially when driving.

If you experience any of these symptoms, it’s important to book a comprehensive eye examination.

Treatment Options for Astigmatism

Glasses and Contact Lenses

Corrective glasses or contact lenses bend light to compensate for the irregular curvature of the cornea. Glasses are a simple, affordable option, while contact lenses offer more freedom but require careful hygiene and can be more costly over time.

Laser and Lens Surgery

Laser eye surgery reshapes the cornea for a permanent solution, ideal for those wanting to avoid glasses or contacts. Refractive lens exchange may be recommended for patients with age-related vision changes or higher prescriptions.

There are several routes you can take to correct your astigmatism, and it is important to have an expert consultation with your optometrist to discuss your options if your vision is affecting your daily activities.
