Soft lenses are also known as daily wear contact lenses, extended wear lenses, silicone hydrogel lenses, and disposable lenses. These lenses are made of lightweight, breathable materials that conform to the shape of the eye. They are designed to be worn for several hours a day and then replaced either daily, weekly, or monthly, depending on the type of lens. Silicone hydrogel lenses have become increasingly popular in recent years due to their high oxygen permeability, which allows for greater comfort and safety during extended wear. Daily wear contact lenses are also available in toric and multifocal designs to correct astigmatism or presbyopia. Ultimately, there are many different types of soft lenses available to fit the individual needs of each wearer.
