Replacement Schedule
Typically, disposable lenses should be replaced at least every one to two weeks. Frequent replacement lenses tend to last a little longer, between one and three months, before needing to be replaced. These lenses are often also referred to as disposable lenses. The final category of contact lenses is traditional lenses, also known as reusable lenses.
Although many people still opt for hard contact lenses, soft lenses continue to be a more popular choice. Hard lenses do not require frequent replacement as they are constructed of a thick plastic and are of an overall more durable quality.
With proper cleaning and care, hard contacts can potentially last up to two years; however, if your eyeglass prescription changes, the lenses are damaged, or the contacts become contaminated, an immediate replacement is recommended. Soft lenses tend to be more comfortable to wear, thanks in part to the thinner material used in the manufacture. Many users favor soft lenses simply because they are easier to get used to wearing and are more affordable to replace compared to hard contacts.

Cleaning solutions for contacts are effective in maintaining good hygiene to protect your eyes; however, over a period of time, natural residue from the eyes can make contact lenses uncomfortable to wear. Natural substances produced by the body such as calcium, lipids, proteins, and bacteria can potentially lead to serious eye infections if contacts aren't replaced on a regular basis.
