Soft lenses can correct many vision problems. They are quite different from gas permeable lenses. The adjustment period is shorter. Dirt and other particles get caught under the lenses less often. They rarely fall out and are easier to insert.
Soft lenses are more expensive than gas permeable lenses.
They are less durable and need to be replaced more often. Also, you need to buy several cleaning and storing solutions for soft lenses. Wearers of soft contact lenses are more likely to get eye infections than wearers of gas permeable lenses. Eye infections must be recognized quickly and treated promptly. Otherwise they can cause serious, sometimes permanent, vision problems.
