Listen to Your Optometrist

• Your optometrist can give you the typical replacement schedule for your particular type of contact lenses. Some are intended for continual wear for seven days and nights, while others are meant for daily wear. Disposable contact lenses typically last for two weeks, one month or three months, according to experts at the All About Vision website.
  
  

Let Your Eyes Tell You

• Eye and vision symptoms will tell you when your contact lenses are getting too old to work properly, according to the Contact Lenses website. Eye discomfort and blurry vision are common signs that wearers should change their contacts. Wearers of multifocus contacts should keep in mind, however, that it can take up to six weeks for most people to get used to wearing multifocals without cloudy vision.
  
  

Bottom Line

• Follow the replacement schedule for your particular type of multifocus contact lenses. Change them early if your eyes start bothering you.
