Optometrists, how to correct astigmatism in your patients?

An ideal optical system is stigmatic, meaning a point object focuses to a single point image. Conversely, in an astigmatic system, a point object focuses on the retina not as a point, but as a surface in the form of an ellipse, disc, or line. The perceived image is thus not clear. Astigmatic individuals may suffer from headaches, eye fatigue, or blurred vision.

Opticians, how can you correct astigmatism in your patients?

An ideal optical system is stigmatic, meaning that an object point focuses on a single image point. Conversely, in an astigmatic system, an object point focuses on the retina not at a single point, but rather on a surface in the form of an ellipse, disk or line. The perceived image is therefore not sharp. People with astigmatism may suffer from headaches, eyestrain or blurred vision.
