I recommend you to choose monthly disposable lenses.
Technically speaking, the shorter the duration of contact lenses last, the less harm they do to your eyes. That's because the longer you wear them, the more germs and dust are on them. They may infect your cornea. Moreover, the shorter time type are thinner and softer, so when they touch your cornea, they are wilder than the longer type.
Then a question appear in your head. According to this theory, the best type should be one-day disposable contact lenses. Why I recommend you the monthly one?
It's because one-day type is too thin and too soft for the beginners to put in their eyes. The hardness of monthly type is just appropriate.
If you have no difficulty in putting contact lenses in your eyes, then one-day proposable type is the best choice for you.
