These lenses are comfortable to wear and must be replaced monthly, weekly, or daily depending on the type you choose. Soft lenses are often recommended for sports because they fit closer to the eye and are more difficult to dislodge. They can provide correction for most prescriptions including astigmatism. Today, with the introduction of newer materials like silicone hydrogels, which allow more oxygen to the eye, patients find it easier than ever to wear soft lenses comfortably.
