Contact lens is very good for sports, hiking, beach and other out door activities. Conventional glasses are not very convenient for they can come off rather easily for sports, and they are not so comfortable with heavy sweating.
Contact lens could be inconvenient for daily work, especially when you have to look at the computer monitor for very long. Your eyes will feel very dry after prolong usage. Disposable contact lens is a very nice choice since they are usually thinner and thus we feel better even for longer usages.
For myself, I will not use contact lens usually unless for sports, and out door activities. Therefore, disposable contact lens is my prime choice! They are inexpensive and easy to buy as well.
