How long can I use my contact lenses before disposing it?
I use disposable contact lenses. I've been wearing (these) contacts now for almost 4 months. I wear them almost everyday of the week, for about 12-14 hours a day. How long should I use each contact before disposing it? And is it a problem if I use a contact lens and within less than a week there is already a small tear at its edge? This has been happening to me several times within the past 3 weeks or so, so I've been throwing out a few lately.
