Contact lens use has a lot of does and don'ts. For how much time you can use it. How to clean it. How to wear and remove. Water content of different duration contact lenses. You must ask all these questions to the one you are buying. Or you can surf the web for detailed information. If used properly then they are safe to use. Do visit an ophthalmologist if you feel any problem in your eye while using lenses and once a year regularly.
