Stabilization is a crucial part of contact lens wear. If contact lenses are not properly stabilized, they can slide or move around the eye, causing irritation, discomfort, and vision impairment. People who wear bifocals or have astigmatism can still wear contact lenses, but additional stabilization techniques may be required to ensure a proper fit.

Most contact lenses are designed to be heavier at the bottom, making them stable and less likely to move or shift during wear. Obtaining a professional fitting is essential to make sure that the lenses are the correct size. Eye care professionals will measure the curvature of the eye, using a keratometer and may have the patient try several different pairs of lenses until the correct fit is found.
Patients who wear bifocals or have astigmatism may require toric lenses, as opposed to traditional soft contact lenses. Unlike soft contact lenses, which come in a wide variety of generic sizes and shapes, toric lenses are customized for the wearer. These lenses are stabilized in the eye by a combination of precise measurements of the curvature of the eye. It is usually necessary for a patient to try more than one pair before finding the right one.
Over time, contact lens prescriptions can change, and for continued quality of vision and stabilization, regular visits to an eye care professional are essential. Proper maintenance and storage of lenses will prevent them from weakening and becoming prone to slippage and movement when worn.
