Contact lenses are a type of corrective eyewear that are worn directly on the surface of the eye. They are a popular alternative to eyeglasses, as they offer a wider field of vision and are less likely to fog up or get dirty. Contact lenses come in a variety of types, including soft contact lenses, hard contact lenses, and gas permeable contact lenses.
The best type of contact lens for you will depend on your individual needs and preferences. Soft contact lenses are the most common type of contact lens, and they are typically made of a soft, flexible material that is comfortable to wear. Hard contact lenses are made of a rigid material, and they are less common than soft contact lenses. Gas permeable contact lenses are made of a material that allows oxygen to pass through, and they are a good option for people who have dry eyes.
