Daily Wear Contacts
Daily Wear Contacts
Daily wear contacts are those that are worn for one day - during waking hours and then taken out. They are then either
cleaned and disinfected to wear again the next morning or thrown away if they are daily wear disposable contacts.
At any rate - they are not slept in.
When people talk about daily wear contacts they are usually referring to soft contacts - but hard contacts, which aren't
hardly worn anymore, were always daily wear. And also RGP - Rigid Gas Permeable - contacts may also be daily wear,
although some are extended wear.
Way back when, when I first started wearing soft contacts they were daily wear only and definitely not disposable. They
were meant to last for some period of time, usually at least a year. And I had some that lasted way more than a year.
It seems then that many people tended to get new ones mostly because they either lost one or tore one. And for some
people they would start getting too many protein deposits on the contacts, so they had to be replaced.
Daily wear soft contacts back then were more or less expected to keep indefinitely, unless something happened to
one, or you had protein deposit problems. It doesn't seem as though they even sell those type anymore, based on some
searches I did. (Of course it could also be that daily contacts that last a year or more are not currently sold
by online stores very much - not enough volume to sell and most people would likely buy them from their eye doctors.)
Most daily wear soft contacts (except the daily disposable type) seem to be more sold as
frequent replacement lenses. Of course I guess it is a matter of opinion about how frequent, frequent is. I found
some that were meant to be replaced every 6 to 18 months. Others every three months. And of course, the daily
disposables - to be replaced each day.
