I have always worn daily soft contact lenses. My Optometrist recommended I try these Night & Day breathable contact lenses that I can wear for up to 30 days without having to remove them. I have had very good luck with these. They were not as delicate as I thought they might be. I don't notice any durability difference between these and my old daily wear lenses. It is such a relief to not have to go through the trouble every night of taking my lenses out and putting them in solution and then having to put them back in again in the morning. The only think I don't like is the price, they are a lot more expensive than the daily wear lenses, even if you figure in the cost of not having to use solutions. But for convenience, they are worth it. I have an astigmatism, and so when I am wearing the lenses I do have to have reading glasses because I can't see to read otherwise.
