Night and day contacts also may be referred to as continuous wear contacts or extended-wear EW contacts. Some EW contacts are approved for up to a week of continuous wear, while others are approved for up to 30 days of continuous wear.
Contacts that can be worn for 30 days straight, like Air Optix Night and Day Aqua, also may be known as monthly contact lenses or day contact lenses.
Night and day contacts may be a good option if you often take naps or accidentally fall asleep in your contacts, and may be a good alternative to laser eye surgery for some patients. That means you may be able to wear these contacts for as long as 30 days and 30 nights without taking them out.
But not everyone can tolerate extended-wear contacts for the maximum time period approved by the FDA. Some wearers will need to take breaks from the lenses during the 30 days and nights. However, extended-wear contacts may increase your risk of some problems. Risks of wearing contacts overnight include:. Corneal ulcer — Some users of extended-wear contacts develop a corneal ulcer that can cause blurry vision, eye pain and redness.
The difference is that other brands of soft contact lenses can be worn for six consecutive nights only. On the contrary, Aqua extended-wear contact lenses have been approved by the Food and Drug Administration FDA to be worn continuously for up to 30 nights. This also prevents eye dryness and uncomfortable contact lens wearing. You must note that reaching the day safe wearability of the Night and Day Aqua Contact Lenses is not true for everyone.
That is because of the fact that we have different sleeping habits, daily activities, and needs, as well as how we respond to contact lens wearing. Your eye care specialist will be the one responsible for determining how long you can wear your contact lenses. Likewise, you must replace your contact lenses after the 30 days or the number of days recommended by your eye specialist.
Also, even if the contact lens can be worn while sleeping and taking a nap, or your doctor permits you to wear it continuously, it is advisable to give your eyes some rest from the contact lens, even for just one night. One of which is losing your contact lens in your eye. This can also occur if you accidentally knocked your eyes on something. Apparently, the likelihood of losing your contact lens is higher if you are wearing your contact lenses while sleeping or taking a nap.
That is because you are not aware of what you are doing while you are fast asleep. On that note, some individuals fear that the contact lens may go behind their eyes. So, what happens when one of your contact lenses gets dislodged?
Well, initially, the soft contact lens will fold and get dislodged from your cornea, and then get stuck under the upper eyelid, but not behind your eye. The good thing is that there are a few ways to do so. That said, before you use any of the techniques provided below, always make sure your hands are clean by washing your hands with soap and water.
But even though these lenses are approved for 30 days of sleeping, most doctors recommend that you leave them out overnight at least once a week. The Air Optix Aqua lenses made by Alcon, Biofinity lenses made by CooperVision, and the Acuvue Oasys lenses made by Vistakon all have FDA approval for six nights of continuous extended wear before they should be removed and left out overnight.
These lenses are a good option for people who usually take their lenses out at night, but sometimes forget. If the lenses are still fresh, they should be safe to use again after soaking in solution overnight. If your eye is a little irritated or dry, use some artificial tears or lubricating drops. If you experience pain, light sensitivity, blurred vision or extreme eye redness after sleeping in them, be sure to contact your eye doctor right away.
