Astigmatism is an eye condition that affects an estimated 25% of people worldwide. It occurs when the eye’s cornea or lens is irregularly shaped, causing blurred or distorted vision. People with astigmatism may experience blurred vision at any distance and may have difficulty seeing both near and far. So, do people with astigmatism see differently than those without?
Symptoms of Astigmatism
The most common symptom of astigmatism is blurred vision, which can occur at any distance. People with astigmatism may also experience eye strain, headaches, and difficulty seeing in low light or at night. Astigmatism can also cause people to experience double vision, where two images of the same object are seen at the same time.
Causes of Astigmatism
Astigmatism is usually caused by an irregularly shaped cornea or lens. This can be caused by injury, genetics, or other factors. Astigmatism can also be caused by nearsightedness or farsightedness, which are caused by the eye focusing light incorrectly.
Effects of Astigmatism
People with astigmatism generally have difficulty seeing both near and far. They may also experience headaches, eye strain, and difficulty seeing in low light or at night. Astigmatism can cause people to have double vision, where two images of the same object are seen at the same time.
Treatment of Astigmatism
The most common treatment for astigmatism is corrective lenses, which can help to correct the shape of the cornea or lens. In some cases, surgery may be recommended. Laser-assisted in situ keratomileusis (LASIK) is a popular surgical option, as it can be used to reshape the cornea.
Conclusion
In conclusion, people with astigmatism may experience blurred vision at any distance and can have difficulty seeing both near and far. Common symptoms include eye strain, headaches, and difficulty seeing in low light or at night. Treatment options include corrective lenses and, in some cases, surgery.
