The convenience extended wear contact lenses provide is amazing. Imagine your contact lenses being worn day and night, you put them in on Monday morning and you forget all about them for a whole week, or maybe even a month. You can leave your contact lens cleaning gear at home and go on a weekend trip, party all night, or work overnight without worrying about storage or cleaning.
Standard contact lenses should only be worn until you fall asleep. Contact lenses that are worn when your eyes are open, provide enough air for the cornea to stay healthy and comfortable. If you close your eyes for a nap or when you go back to bed, it reduces the amount of oxygen available, which can significantly affect the quality of your contact lens' breathability. The condition is known as corneal hypoxia and is a serious problem that can be caused by sleeping with standard contacts in your eyes.
So you can see that there are safety concerns when wearing contact lenses while sleeping. If you're considering switching to continuous wear contact lenses, talk with your optometrist first. It is absolutely safe, however, the lens you select must be appropriate for your particular patient needs. This is not something you should do on your own without professional advice first.
Contact lenses for extended wear are made to give your eyes as much oxygen as possible. They can be worn continuously for 7 nights, 14 nights, or 30 nights depending on the particulars of the lens and your optician recommendations. There is no risk to your eyes health when used properly. Contact lens manufacturers have invented new, ultra-breathable materials that are extremely gas permeable and have come up with innovative designs to reduce the thickness of lenses while improving or maintaining their visual performance. Extended wear lenses, which aren't removed for many days, also use special technologies to prevent deposits from building upon their surface. They are comfortable and offer excellent vision. They can stay clean for as little as a few days to up to 4 weeks.
One of the most important characteristics of contact lenses is oxygen permeability. In lenses, Dk/t is used to denote the lens thickness. Oxygen permeability refers to how much oxygen can pass through a lens into the cornea. This is crucial, especially at night. The cornea receives only 30% of the oxygen it normally receives when the eyelids remain closed. This is why oxygen permeability is the most critical factor in determining whether a product should be used during sleep. Different contact lens manufacturers offer different levels of safe permeability. You might be surprised at how many products have been approved to be used during sleep. When choosing lenses for continuous wear, it is important to follow the advice of your eye doctor. When making your decision, it is worthwhile to start with the most breathable.
Remember that your lenses will last a very limited amount of time. You need to replace them in line with the manufacturer's recommendations or, more importantly, those of your eye care specialist. Continuous wear lenses particularly require this because they are often worn for long periods of time. If the lens is not cleaned or disinfected frequently, then protein deposits will eventually form. This can result in complications and infection. While the lenses' materials are highly resistant to the buildup of deposits, this is still a very individual matter. It is best to follow the replacement schedule. A quality lens care cleaning solution can help keep your contacts in great shape and tip-top condition for longer. Eye drops are also great at keeping your eyes feeling hydrated and fresh.
We only feature trusted brands, which are proven safe and have been recommended by optometrists worldwide for many years. Air Optix Night & Day Aqua is currently the most breathable lens on the marketplace. Its Dk/t rate is 175 for a power -3.00. Although oxygen permeability varies depending on the lens' spherical power, Dk/t was used for the comparison. Acuvue Oasys can have 147 Dk/t and Biofinity lenses can boast oxygen permeability as high as 160 Dk/t. PureVision 2 & PureVision 2 for Presbyopia have a 130 Dk/t. The values of the parameter may vary between the lenses. For example, Biofinity Toric and PureVision 2 for Presbyopia are different. These lenses are still permeable enough to be worn while you sleep.
If you are looking for lenses for continuous wear, make sure to consult a specialist before you place an order. Also, never use lenses that have not been designed for this purpose. It is possible to have complications when you sleep in lenses that have low oxygen permeability or inadequate hydration.
