Astigmatism vs. Stigmatism
Astigmatism and stigmatism are two distinct conditions that affect the clarity of vision. Astigmatism occurs when the cornea or lens of the eye is not perfectly round, causing light to focus unevenly on the retina. This results in blurred or distorted vision at all distances. Stigmatism, on the other hand, is a condition in which the cornea or lens is perfectly round, but the light entering the eye is not properly focused on the retina. This can also lead to blurred or distorted vision, but it is usually only noticeable at certain distances.
Astigmatism is a very common condition, affecting about one-third of the population. It is usually diagnosed during an eye exam and can be corrected with glasses, contact lenses, or refractive surgery. Stigmatism is a less common condition, but it can also be corrected with glasses or contact lenses.

The causes of astigmatism and stigmatism are important to understand in order to properly diagnose and treat these conditions. Astigmatism is caused by an irregularly shaped cornea or lens, which prevents light from focusing evenly on the retina. Stigmatism, on the other hand, is caused by an uneven distribution of refractive power in the eye, which also prevents light from focusing evenly on the retina. Both of these conditions can be corrected with glasses, contact lenses, or refractive surgery.
Symptoms
Astigmatism and stigmatism are two common eye conditions that can cause blurred or distorted vision. While astigmatism can cause blurred or distorted vision at all distances, stigmatism only causes blurred or distorted vision at certain distances. This is because astigmatism is caused by an irregularly shaped cornea or lens, which prevents light from focusing evenly on the retina. Stigmatism, on the other hand, is caused by an uneven distribution of refractive power in the eye, which also prevents light from focusing evenly on the retina.
- Blurred or distorted vision at all distances: This is a common symptom of astigmatism. People with astigmatism may have difficulty seeing clearly at all distances, both near and far.
- Blurred or distorted vision at certain distances: This is a common symptom of stigmatism. People with stigmatism may have difficulty seeing clearly at certain distances, such as when reading or driving.
- Eyestrain: Astigmatism and stigmatism can both cause eyestrain, which can lead to headaches, fatigue, and difficulty concentrating.
- Double vision: In some cases, astigmatism and stigmatism can cause double vision, which can make it difficult to see clearly.
If you are experiencing any of these symptoms, it is important to see an eye doctor to rule out any underlying eye conditions.
Diagnosis
During a comprehensive eye exam, an eye doctor will use a variety of tests to check for astigmatism and stigmatism. These tests may include:
- Visual acuity test: This test measures how well you can see at different distances.
- Retinoscopy: This test uses a lighted instrument to measure the refractive error of your eye.
- Autorefraction: This test uses a machine to measure the refractive error of your eye.
- Corneal topography: This test uses a machine to create a map of the curvature of your cornea.
Once your eye doctor has diagnosed you with astigmatism or stigmatism, they will prescribe the best treatment option for you. Treatment options may include glasses, contact lenses, or refractive surgery.
Treatment
Astigmatism and stigmatism are two common eye conditions that can cause blurred or distorted vision. While astigmatism is caused by an irregularly shaped cornea or lens, stigmatism is caused by an uneven distribution of refractive power in the eye. Both conditions can be diagnosed during a comprehensive eye exam and can be corrected with glasses, contact lenses, or refractive surgery.
The type of treatment that is best for you will depend on the severity of your astigmatism or stigmatism and your individual needs. Glasses and contact lenses are the most common treatments for both conditions. Glasses work by bending light to correct the refractive error of the eye, while contact lenses work by changing the shape of the cornea.
Refractive surgery is a permanent solution for astigmatism and stigmatism. Refractive surgery uses lasers to reshape the cornea and correct the refractive error of the eye. This can be a good option for people who are not satisfied with the results of glasses or contact lenses or who want to avoid wearing corrective lenses altogether.
If you are experiencing blurred or distorted vision, it is important to see an eye doctor to rule out any underlying eye conditions. Your eye doctor can diagnose astigmatism or stigmatism and recommend the best treatment option for you.

Impact on vision
Astigmatism and stigmatism are two distinct eye conditions that can affect the clarity of vision. Astigmatism is caused by an irregularly shaped cornea or lens, while stigmatism is caused by an uneven distribution of refractive power in the eye. Both conditions can be diagnosed during a comprehensive eye exam and can be corrected with glasses, contact lenses, or refractive surgery.
- Blurred or distorted vision: Both astigmatism and stigmatism can cause blurred or distorted vision. However, astigmatism is more likely to cause blurred or distorted vision at all distances, while stigmatism is more likely to cause blurred or distorted vision at certain distances.
- Driving difficulties: Astigmatism and stigmatism can both make it difficult to drive safely. This is because blurred or distorted vision can make it difficult to see road signs, other vehicles, and pedestrians.
- Eye strain: Astigmatism and stigmatism can both cause eye strain, which can lead to headaches, fatigue, and difficulty concentrating.
The impact of astigmatism and stigmatism on vision can vary depending on the severity of the condition. In some cases, astigmatism or stigmatism may only cause mild blurred or distorted vision. In other cases, astigmatism or stigmatism may cause significant blurred or distorted vision that can interfere with daily activities.
Management
Astigmatism and stigmatism are two common eye conditions that can cause blurred or distorted vision. While astigmatism is caused by an irregularly shaped cornea or lens, stigmatism is caused by an uneven distribution of refractive power in the eye. Both conditions can be diagnosed during a comprehensive eye exam and can be corrected with glasses, contact lenses, or refractive surgery.
Corrective lenses, such as glasses or contact lenses, work by bending light to correct the refractive error of the eye. Refractive surgery, on the other hand, uses lasers to reshape the cornea and correct the refractive error of the eye. Both corrective lenses and refractive surgery can be effective in managing astigmatism and stigmatism.
The choice of treatment will depend on the severity of the condition and the individual needs of the patient. For mild to moderate astigmatism or stigmatism, corrective lenses may be sufficient to improve vision. For more severe cases, refractive surgery may be a better option.
Managing astigmatism and stigmatism is important for maintaining good vision and preventing further eye problems. If you are experiencing blurred or distorted vision, it is important to see an eye doctor to rule out any underlying eye conditions and to discuss the best treatment options for you.
