What is the purpose of using sterile saline during the removal of contact lenses?

The use of sterile saline during the removal of contact lenses primarily serves to maintain moisture. This is critical because contact lenses are designed to sit on the surface of the eye, and when they are removed, the eye can become dry, particularly if the lenses have been worn for an extended period. By using sterile saline, you help to hydrate both the lens and the eye, which can make the removal process more comfortable and reduce the risk of irritation or damage to the cornea.

Moisture is essential during this process to ensure that the lenses come off easily and do not adhere to the eye. Additionally, maintaining moisture helps to alleviate any discomfort that may occur during lens removal, promoting a smoother experience. Without adequate moisture, there could be increased friction or stress on the eye, potentially leading to complications.

Other options such as disinfecting the lenses or cleaning fingers might be necessary in the overall lens maintenance process, but they don't directly relate to the primary function of the sterile saline during the removal operation.
