Multifocal contact lenses allow you to view objects in focus at both close and faraway distances. They work by allowing light in through different lens prescriptions located on the contact lens so contact wearers don't have to choose between seeing at one distance or another. However, most wearers experience a period of discomfort and object confusion when they first begin to wear these types of contacts.
Give your brain time to get used to this new way of seeing things. Adjusting to these contact lenses is really about giving your brain time to sort through blurry and clear objects to decide which ones it wants to see, and how to filter out the blurry objects. Because you're looking through two different prescriptions at the same time, objects will appear both clear and blurry at both distances for some time. Don't expect to adjust to the new lenses overnight; it may take a few weeks.
Wear your contacts at all times during the day. Even though it may get frustrating, removing the contacts for half the day will only slow down or reverse your brain's adjustment process. Continued exposure of sight through these lenses lets your brain learn how to adjust to them.
Return to your eye doctor for a checkup. Sometimes, a certain type of multifocal contact lenses won't work for some patients. Returning to your eye doctor to asses the situation and make sure you have the correct measurements may help you find a better brand or type of multifocal contacts for you to use.
The typical adjustment period for these types of contacts lasts for about two weeks, depending one the difference in prescriptions and the patient's previous experiences with multifocal lenses.
