Contact lenses are replacements for spectacles, usually meant for people who just can’t go without corrective lenses, but don’t want the hassle of wearing spectacles all the time. There’s a tradeoff though, using and maintaining contact lenses is a bit more complicated than a good ol’ pair of spectacles, which is why a lot of people don’t prefer it. One of the main reasons people do not opt for contact lenses is the cleaning process, because contact lenses have to be soaked in a solution and cleaned carefully every single day.
