Contacts are convenient and easy once we get used to them but they still are medical devices sitting directly on your eyeball and there are plenty of situations where things can go very wrong. Also, you really are supposed to own a pair of glasses for the situations in which you cannot safely wear contacts which effectively makes contacts a luxury item, not really suitable for people who cannot afford the fitting and health check nor the follow up visits in a situation where something goes wrong (e.g. an eye infection). Recently my sister saw a patient who lost partial vision because she had an infection and just put some Visine drops in (it constricts the blood vessels reducing their appearance, which exacerbated her health issue) and wore her contacts anyway for several days, ignoring the pain. That is an extreme example but contacts are a whole 'nother can of worms compared to glasses. It isn't really as simple as having your prescription and your fit and sending you on your way. And it is really best to follow the doctor's suggestions, don't overwear, use the solution as directed, keep them out when you eye is irritated, etc.
