Why do I still need glasses when I wear contact lenses?
Most people cannot leave their contact lenses in all day, every day, and expect their eyes to remain healthy. It is best to let your eyes breathe normally at least every evening and preferably one whole day a week, by not wearing your contact lenses. Therefore, you need up to date glasses to use. Also, your eyes may feel irritated by the contact lenses or you may get an eye infection, in which case you would need glasses to wear instead. If you do not have up to date glasses, you become tempted to keep your contact lenses in for too long.
