These lenses tend to be more durable and retain their shape well, and they are less prone to dehydration, making them suitable for extended wear. Low oxygen permeability, solid lenses, and uncomfortable wearing experience are the drawbacks of low water content.

The extra moisture can reduce eye dryness, itchiness, and the feeling of foreign objects in the eye, making them more comfortable to wear.
