Oxygen permeability ideal for extended wear
Extended wear contacts offer incredible convenience. Imagine putting on your lenses Monday morning and not thinking about them for a week, or even a month. It would be possible to go on an overnight trip or to a wild weekend party without worrying about cleaning solutions, replacement lenses, or storage cases.
Standard contact lenses are only safe to wear until you go to bed. This is because these contact lenses are safe to wear only if your eyes are mostly open. Extended wear lenses provide more air for the cornea, which is essential for maintaining its health and comfort. Your contact lenses' breathability is affected if your eyelids are closed like when you go to sleep. Corneal hypoxia, a condition that affects the eyes and can cause serious complications. This is what you could experience if you sleep with standard contact lenses.
Safety considerations when using contact lenses for sleeping are well-founded. Anyone considering switching to 24/7 lenses should talk with their optometrist first. Answering the question in the title is yes you can sleep in contact lenses. However, you must use the correct lenses for the purpose. The individual characteristics of each patient should also be considered when deciding whether to use the lenses. This is something you shouldn't do on your own - always ask your optician.
Contact lenses that are extended-wear can provide more oxygen to your eyes by being more oxygen permeable. They have been tested to ensure that they can be worn for a certain number of days and nights without affecting your eyes' health. Contact lens manufacturers have created new, highly breathable materials for just this purpose. They also have innovative designs that make them thinner while maintaining or improving their visual performance. Extended wear contact lenses are also made with special technologies to prevent any deposits from building up. They feel great and give you excellent vision. And depending on the user, they don't need to be cleaned for several weeks.
Contact lenses can be defined by oxygen permeability. This parameter is known as Dk/t in lenses. "t" is the thickness of the lens. The cornea's ability to absorb oxygen from a lens is called its oxygen permeability. This is especially important at night because the cornea receives 30% less oxygen when the eyes are closed compared to when they are open. The most important factor in determining whether a product can be used for sleep is exactly this, oxygen permeability. You may be surprised at the differences in the levels of oxygen transfer between different manufacturers. Your eye specialist should be consulted when selecting lenses for continuous wear. It is also worth choosing lenses that are the most breathable when starting out with this kind of lens.
Wearing normal lenses 24 hours a day is not advisable. Instead, you should replace them according to the manufacturer's schedule or your specialist's advice. With Continuous wear it is especially important because they can stay on the eyes for a long period of time without being cleaned or disinfected. Protein deposits build up over their lives and cause them to become contaminated. This can increase the risk of complications and infection. Although extended wear contact lenses can withstand the buildup of deposits due to their materials, it is not recommended to omit the replacement schedule. We highly recommend regularly soaking in quality lens care solutions. This helps to keep them in top condition and keep them feeling fresh and comfortable.

PureVision 2 and PureVision 2 For Presbyopia claim 130 Dk/t. You should also remember that different lenses (e.g. Biofinity Toric) have different values for this parameter. They are still high enough that they can be used while you sleep.
