What is a common characteristic of soft toric contact lenses?

Soft toric contact lenses are designed to correct astigmatism, which is a condition where the eye does not focus light evenly onto the retina due to an irregular shape of the cornea. A common characteristic of these lenses is that they often require stabilization methods to maintain a proper orientation on the eye. Unlike spherical lenses, which can rotate freely without significantly affecting vision, toric lenses must align in a specific way to ensure that the correct meridians of correction are positioned properly in relation to the eye's surface.

Stabilization techniques can include design features like ballast (heavier areas at the bottom of the lens), thin zones, or prism to help the lens orient correctly once placed on the eye. This is crucial because any misalignment can lead to blurred or distorted vision. Consequently, the need for stabilization methods is essential for optimal performance of soft toric lenses, making this a defining characteristic of their design.

In contrast, other options do not accurately represent the characteristics of soft toric contact lenses. For example, while they are generally comfortable, discomfort can still occur for various reasons, such as dryness or improper fit. Additionally, fitting adjustments are often necessary to ensure the lenses are correctly positioned on the eyes. Lastly, soft toric
