Astigmatism is a common vision issue caused by an irregular curvature of the cornea or lens. This uneven shape prevents light from focusing evenly on the retina, often leading to blurry, distorted, or stretched vision at all distances.
Fortunately, astigmatism is highly treatable. From glasses and contacts to laser vision correction like LASIK, several options are available to help you achieve clearer sight and greater visual comfort.
Astigmatism is a type of refractive error—alongside nearsightedness and farsightedness—that disrupts how light focuses on the retina. Instead of focusing at a single point, light scatters, causing blurred or warped vision.
| Type | Description |
|---|---|
| Corneal Astigmatism | Irregular curvature of the front surface (cornea) |
| Lenticular Astigmatism | Irregular shape of the internal lens |
Both types can distort vision horizontally, vertically, or diagonally—depending on how the light is refracted.
Astigmatism can be present from birth or develop later in life due to a variety of factors:
Astigmatism is often an inherited condition, passed down from one’s parents. The shape of the cornea or lens can vary from person to person, and this genetic predisposition can contribute to the development of astigmatism.
Certain eye injuries, such as a corneal scar or eye surgery, can alter the shape of the cornea and lead to astigmatism. Additionally, eye diseases like keratoconus can cause the cornea to become irregularly shaped, resulting in astigmatism.
As we grow older, the natural lens inside the eye can undergo changes that may lead to the development of astigmatism. This is a common occurrence, and it’s important to have regular eye exams to monitor for any changes.
Astigmatism symptoms can vary in severity and may include:
Since children may not realize their vision is unclear, regular eye examinations are essential for early diagnosis and intervention.
Astigmatism can be diagnosed through a comprehensive eye examination conducted by an ophthalmologist or optometrist. The following tests are typically used:
These tests provide a detailed assessment of your eye’s structure and function, allowing your eye care professional to accurately diagnose and determine the appropriate treatment for your astigmatism.
There are several effective treatment options for astigmatism, ranging from corrective lenses to surgical procedures. The choice of treatment often depends on the severity of the condition and individual lifestyle needs.
For those looking for a long-term solution, LASIK surgery is a highly effective option. The procedure involves using a laser to reshape the cornea, correcting the irregular curvature responsible for astigmatism. LASIK can be particularly beneficial for those with astigmatism who seek to reduce or eliminate their dependence on corrective lenses.
It is essential to consult with an ophthalmologist to determine whether LASIK is a suitable option, as not everyone may be a candidate for the procedure.
Astigmatism may be common, but it doesn’t have to compromise your vision. From corrective lenses to advanced solutions like LASIK, today’s treatments offer effective, personalized results.
If you’re noticing blurry vision or other signs of astigmatism, schedule a comprehensive eye exam with a trusted vision specialist. With the right diagnosis and care, clearer vision could be just a few steps away.
