Soft contact lenses are thin, flexible lenses made from soft plastic materials that allow oxygen to pass through to the eye. They are designed to correct vision problems such as nearsightedness, farsightedness, and astigmatism. Soft lenses are comfortable to wear and can be used for daily wear or extended wear, depending on the type. These lenses come in various types, including daily disposables, which are worn for a single day, and monthly disposables, which can be worn for several weeks. Proper care and hygiene are essential to maintain eye health while using soft contact lenses.
