People can use lenses {contact lens}| that adhere to cornea. Contact lenses are safer in contact sports and are good lenses for magnifying and for correcting astigmatism. They can clean at night. People can replace soft lenses yearly, quarterly, monthly, or weekly. They fit closer to eye and so move less and fall out less. Soft lenses can be daily-wear or extended-wear. Rigid gas-permeable lenses are harder and allow sharper vision.
