What type of astigmatism is commonly associated with aging?

With-the-rule astigmatism is commonly associated with aging due to the natural changes that occur in the eye's shape and corneal curvature as a person gets older. In this particular type of astigmatism, the steepest curvature of the cornea is oriented vertically. This condition often develops as individuals age, resulting from progressive changes in the lens and cornea, leading to a tendency for the cornea to have a more pronounced vertical meridian.

As people age, structural changes within the eye can lead to variations in how light is refracted, which impacts vision quality. With-the-rule astigmatism is characterized by the fact that it often develops in a manner that aligns with common age-related shifts in corneal shape, making it a typical finding in older adults.

Other types of astigmatism, like against-the-rule and irregular astigmatism, may not be as closely linked to the aging process and can arise from different causes, such as keratoconus or trauma. Toric astigmatism refers to the use of specific lens designs to correct astigmatism but does not specify a type related to aging directly. Therefore, the identification of with-the-rule astigmatism as the correct
