Stigmatism and astigmatism are two common eye conditions that can cause blurred 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 be focused incorrectly on the retina, the light-sensitive tissue at the back of the eye. Astigmatism is a condition in which the cornea is curved more in one direction than the other. This can also cause light to be focused incorrectly on the retina.

Both stigmatism and astigmatism can be corrected with eyeglasses or contact lenses. In some cases, surgery may also be an option.

It is important to have regular eye exams to check for stigmatism and astigmatism. Early diagnosis and treatment can help to prevent vision problems from developing.
