What is the main reason to fit a Ballasted lens?

Fitting a ballasted lens primarily serves the purpose of reducing lens rotation. Ballasted lenses are designed with an added weight or thicker portion that helps to stabilize the lens on the eye, which is particularly important for patients with higher prescriptions or those requiring specific optical performances, such as toric lenses for astigmatism.

The weighted design of a ballasted lens ensures that it remains in a consistent position on the cornea, allowing for optimal visual acuity and preventing the distortion of vision that could occur from excessive lens movement. This stability is crucial for ensuring that the optical axis of the lens remains aligned with the visual axis of the eye, thereby enhancing the overall effectiveness of the lens.

By focusing on the need for less rotation, practitioners can provide patients with a more comfortable experience and better visual results, ultimately making ballasted lenses a valuable option in certain fittings.
