What type of lens is most likely to be affected by lens eversion?

The correct choice is conventional soft lenses because they are typically more flexible and have a greater surface area that can be influenced by factors such as pressure from the eyelid or movement of the eye. When the eyelid closes, it can cause these lenses to flip or evert, especially if they are not properly centered or if there is an issue with the fit.

Conventional soft lenses are also made of materials that can absorb moisture, which allows them to be somewhat pliable and more likely to respond to changes in eye movement.

Rigid gas permeable lenses, while they can sometimes be dislodged, tend to retain their shape better and do not evert as easily due to their firmer structure. Silicone hydrogel lenses, similar to conventional soft lenses, can also be affected by eversion but might have a more stable fit due to their design and material properties. Hybrid lenses, which combine a rigid center with a soft skirt, may resist eversion as well due to their unique structure.

Thus, traditional soft lenses stand out as the most prone to this issue, making them the answer that aligns with the question regarding lens eversion.
