Contact lenses are primarily used to correct vision problems. Many different types of material are used in making the lenses. Consult an ophthalmologist as to which is best for you.
Types
Since 2000, the modern trend is toward disposable lenses. According to Consumer Reports, different types of lenses are designed to be disposed of daily, monthly or at intervals up to twelve weeks.
Risk
Consumer Reports points that that the risk of infection due to contacts is only four to twenty cases per 10000 wearers. Chances of infection can be minimized by replacing the cleaning solution every three months.
Warning
In April, 2010, the American Academy of Ophthalmology warned against cheap contact lenses distributed without a prescription. The warning included a reminder that only a doctor can properly fit lenses.
