What is Astigmatism? Causes, Symptoms, and Treatment Options

What is Astigmatism? Causes, Symptoms, and Treatment Options

Astigmatism is a common refractive error that affects how light rays focus on the retina, resulting in blurred or distorted vision.

Unlike nearsightedness (myopia) or farsightedness (hyperopia), which occur when the cornea or lens has a single focal point, astigmatism occurs when the cornea or lens has an irregular shape, causing light rays to focus at multiple points instead of a single point. This irregular curvature can lead to blurred vision at all distances and may cause objects to appear stretched or elongated.

Astigmatism is a common condition, affecting approximately one in three people to some degree.

It can occur in combination with other refractive errors or as an isolated condition. While astigmatism can occur at any age, it often develops early in life and may change over time.


Symptoms of astigmatism can vary depending on the severity of the condition but may include:
- blurred or distorted vision
- eye strain
- headaches
- squinting
- difficulty seeing clearly at night

Some individuals with astigmatism may also experience ghosting or double vision, particularly in low-light conditions.

While astigmatism itself does not cause pain or discomfort, it can significantly impact visual clarity and quality of life if left uncorrected.

Fortunately, astigmatism can be easily diagnosed during a comprehensive eye examination conducted by an optometrist or ophthalmologist. During the exam, the eye care professional will perform various tests, including visual acuity testing, refraction assessment, and corneal topography, to determine the presence and severity of astigmatism.

As explained, astigmatism is a common and manageable refractive error that affects millions of people worldwide. It's essential to understand that having astigmatism is not a serious condition, and with the right corrective measures, clear vision can be easily achieved.

Wearing glasses or contact lenses is the most common and effective way to correct astigmatism and improve vision.

Prescription lenses designed for astigmatism are specially crafted with a cylindrical lens prescription to compensate for the irregular curvature of the cornea or lens. These lenses may also incorporate a spherical lens component to address any accompanying nearsightedness or farsightedness, ensuring comprehensive vision correction.

When selecting glasses to correct astigmatism, it's important to choose frames that provide adequate coverage and stability for the prescription lenses. Fortunately, most glasses available on PRET A VOIR are suitable for individuals with astigmatism.

Your optician will provide you with a precise prescription after your eye test, including the measurements required to combat your astigmatism effectively. You can upload, or manually enter, your details in our prescription form found on our product pages. Our trained customer care team and dispensing opticians will then use this information when creating the lenses for your new glasses.

Frames with adjustable nose pads and temple arms can help ensure a comfortable and secure fit, enhancing the overall wearing experience. Additionally, lightweight materials like titanium or acetate offer durability and style without compromising on comfort.

Rest assured that by following your optician's guidance, our team can assist you in selecting the appropriate frames and lenses for your prescription. You can comfortably manage your astigmatism and enjoy clear vision in your daily life.

Astigmatism may be common, but with the right corrective measures, it's a condition that can be effectively addressed, allowing you to see the world with clarity and confidence.
