Contact lenses replace glasses and are available as 1-day lenses, monthly lenses, weekly lenses, and three-month lenses. Usually, you only use the lenses during the day and not at night but there are special contact lenses that work even when you sleep. There are also lenses with UV protection and special patterns. Choose carefully by strength, size, type of contact lens and material.
