Yes, it is ok to wear monthly contact lenses. It is hard to say that whether monthly contact lenses are better than daily disposable contacts or not. It depends on your need because both of them have their own advantage. In term of health and safe, I think daily disposable contact lenses are much better than monthly contact lenses. Daily disposable contact lenses are used only for one day. Monthly contact lenses must clean with contact-lens fluid every day you stop using them and you may not clean up the cover of the contact lenses. That will have dirty thing on them. So, it cleaner and safer to use daily disposable contact lenses. However, in term of quality and price, monthly contact lenses are better than daily disposable contact lenses. Because monthly contact lenses are used for a month, so they are made in better material and they can be easily to wear. And their prices are more expensive than daily disposable contact lenses. At last, I want to say that if you use your contact lenses only few times and want to have least damage to your eyes, I advise you to use daily disposable contact lenses. If you want use your contacts more times and use least money, I advise you to use monthly contact lenses.
