Learn More About Astigmatism

What is Astigmatism?

Astigmatism is a common vision condition that occurs when the cornea or lens of the eye has an irregular shape. Instead of being perfectly round, like a basketball, the cornea or lens is shaped more like a football. This irregularity causes light to be focused on multiple points in the eye, leading to blurred or distorted vision. Astigmatism can occur in combination with nearsightedness (myopia) or farsightedness (hyperopia), and can vary in severity.

The difference between normal vision and astigmatism in the eyeWhat Does Astigmatism Look Like?

Individuals with astigmatism often experience visual distortions that can make everyday activities challenging. Images may appear stretched out or blurred, and straight lines can look wavy or slanted. These distortions can significantly impact reading, driving, and other tasks that require clear vision. Common symptoms include:

  • Blurred or fuzzy vision at all distances
  • Difficulty seeing at night
  • Eyestrain or discomfort
  • Headaches
  • Squinting to see clearly/reduce glare

Does Astigmatism Affect Night Time Driving?

Yes, astigmatism can particularly affect night-time driving. Reduced light levels at night can exacerbate the symptoms of astigmatism, making it harder to see clearly. People with astigmatism often experience:

  • Glare and halos around lights
  • Increased sensitivity to bright lights
  • Difficulty focusing on objects in low light conditions

These symptoms can make night driving more dangerous, as the ability to judge distances and recognize road signs is impaired. It’s important for individuals with astigmatism to take extra precautions and ensure their vision is adequately corrected when driving at night.

Lenses for Night Time Driving

Personalized lenses like the HOYA EnRoute or Zeiss DriveSafe both offer contrast enhancing filters combined with superior digital optics to enhance your vision in low light scenarios like driving at night. These lenses are designed with a digital surfacing technology to make the most effective pair of glasses with your astigmatism correction, allowing a safer and more comfortable driving experience. These lenses come in single vision (distance correct only) or progressive designs to correct vision for anyone that requires the best vision for driving at night.

How Can I Correct Astigmatism?

Without intervention, astigmatism does not often improve and the condition will either remain stable or deteriorate as you age. Occasionally, astigmatism can improve over time, reducing the need for glasses or contact lenses to correct it. Depending on the severity of the condition, and individual preferences, there are several effective methods to correct astigmatism:


Eyeglasses are the simplest and most common way to correct astigmatism. Special lenses, called toric lenses, are designed to compensate for the irregular shape of the cornea or lens and help focus light properly on the retina, providing clear vision.

Contact Lenses

Contact lenses can also correct astigmatism. Toric contact lenses are specifically designed to address the unique curvature of the eye, offering a comfortable and effective solution for many people. Soft contact lenses may be a good choice for individuals with a minor astigmatism.

Hard shell contacts, such as Rigid Gas Permeable (RGP) lenses are another option, particularly for those with a higher astigmatism, providing sharper vision by maintaining their shape on the eye.

Laser Eye Surgery

For those seeking a more permanent solution, laser eye surgery (such as LASIK or PRK) can reshape the cornea, correcting the irregular curvature and improving vision. This option is suitable for many, but not all, individuals with astigmatism, and a thorough evaluation by an eye care professional is necessary to determine eligibility.
