Replacement and Wearing Schedules

Posted by CooperVision on Wednesday, August 22, 2012

A replacement schedule is the length of time your contacts can be worn before they need to be replaced with new lenses (taking them out at night is a given unless you have "extended wear" contacts). Your eye doctor can help you decide what the best replacement and wearing schedule for you is based on your lifestyle and vision correction needs. Here is a list of the different replacement schedule options you can discuss with your eye doctor.

Daily Disposable

This replacement schedule is ideal for patients who may suffer from allergies from contact lens solutions because daily disposable contact lenses eliminate the need for lens cleaning or disinfection. Since daily disposable contact lenses are replaced each day, they're also the healthiest lens option and can help those that suffer from ocular allergies. CooperVision makes great daily disposable contact lens options. One option is Proclear 1 Day contact lenses. They are made with PC Technologyâ„¢, which is a lens material that contains molecules found naturally in human cell membranes. These molecules attract and surround themselves with water, keeping Proclear contact lenses moist and comfortable, even after 12 hours of wear. In fact, Proclear lenses are the only contact lenses for dry eyes with FDA clearance for the claim: "may provide improved comfort for contact lens wearers who experience mild discomfort or symptoms relating to dryness during lens wear."

Two Week

Contact lenses that are replaced every two weeks are also known as disposable lenses. It is the most popular replacement schedule in the U.S. because of a combination of affordability and convenience. CooperVision offers Avaira contact lenses in this replacement schedule. Avaira contact lenses are made from material that uses Aquaform® Comfort Science Technology. As a result, the lens material is a softer, more flexible one, contributing to Avaira's extremely comfortable lens wearing experience.


This replacement schedule is when contact lenses are replaced on a monthly basis. This schedule is convenient because it contains contact lenses that are made from silicone hydrogel materials that are FDA approved for extended wear. These materials offer the highest levels of oxygen to the eye, which significantly reduces the effects of hypoxic stress to the cornea. Extended wear is when a contact lens wearer chooses to sleep in their contact lenses. CooperVision offers a monthly contact lens line called Biofinity for this replacement schedule. It is FDA approved for 6 nights and 7 days of extended wear. Patients who choose to wear monthly lenses for extended wear should consult their eye doctor about their exact replacement schedule.

As long as the contact lenses are properly cared for and a patient follows the replacement schedule recommended by his/her eye doctor, contact lenses are a safe and convenient option for correcting vision. Make sure to talk to your eye doctor about you contact lens options. No matter what replacement schedule you choose, CooperVision is sure to have a contact lens for you.

Defense! Defense!

Posted by Harvard Sylvan, OD on Thursday, December 31, 2009

“DEFENSE!! DEFENSE!!” is frequently shouted during basketball and football games. Defense, according to, is a noun meaning protection and resistance against attack. But what does defense have to do with contact lenses? Think of replacing your contact lenses at the interval prescribed by your eye care practitioner as your DEFENSE  when wearing contact lenses. 


Defense against what? A common misconception is that tears are made of only water. While water is the main component, there are actually hundreds of substances found in tears.  Other important components include mucins (natural lubricants), oils, electrolytes (such as sodium chloride and potassium) and proteins (that defend against bacteria and other organisms).  As soon as a lens is placed on the eye, it will start to absorb some of these components, particularly proteins and oils.  Over a short period of time, deposits can form on the lens.  Deposits reduce comfort and vision and can cause allergic-type reactions, particularly under the upper lid.  Deposits also reduce the amount of oxygen that can pass through the lens. That can cause changes to the outer layer of the cornea that may allow bacteria or other organisms to infiltrate the cornea and cause an infection. The amount of deposits will vary depending on the contact lens material and the tear composition of the individual.  For example, some people naturally have more protein in their tears than others. Some lens materials are more resistant to protein deposits than other materials.


An eye care practitioner will select a replacement schedule for a patient after a careful evaluation of the patient’s ocular health, tears, lifestyle and the contact lens material.  The idea is to replace lenses before deposits form and before any problems develop. Even if a lens is still comfortable at the end of the replacement period it should still be replaced.  Many contact lens related problems are only evident to the eye care practitioner and not the wearer.


For those of you who wear one day lenses, it is easier to remember when to replace them as you discard your lenses after each day of wear.  It is more difficult to remember to replace lenses on a two week or a monthly cycle. We suggest writing the prescribed replacement date on a post it note and placing it on the mirror in your bathroom or on your computer screen.  If you are digital, put a reminder in your Outlook or iCal calendar.  Syncing up your replacement schedule with natural habits helps maintain comfortable and healthy contact lens wear! 


Replacing lenses on the schedule prescribed by your eye care practitioner will minimize complications, maximize comfort and contribute significantly to successful contact lens wear.  Whether you replace your lenses each day, every two weeks or every month, remember to chant “DEFENSE!! DEFENSE!!” when you discard those lenses at the proper time.
