Stigmatism and astigmatism are two distinct but related conditions that affect the vision. Stigmatism is a condition in which the cornea, the clear outer layer of the eye, is not perfectly round. This can cause light to focus incorrectly on the retina, the light-sensitive tissue at the back of the eye. Astigmatism is a condition in which the cornea or lens is not perfectly curved, causing light to focus in more than one place on the retina.
Both stigmatism and astigmatism can cause blurred vision, difficulty seeing fine details, and eye strain. However, stigmatism is typically less severe than astigmatism. Stigmatism can often be corrected with eyeglasses or contact lenses, while astigmatism may require more specialized treatment, such as laser eye surgery.
Stigmatism and astigmatism are common conditions, affecting millions of people worldwide. They can occur at any age, but they are most common in adults. Early diagnosis and treatment of stigmatism and astigmatism can help to prevent vision problems from developing.
