Wearing contact lenses or colored lenses at night while sleeping is not recommended. However, a short nap with your contact lenses in isn't a big deal either. Our optician, Sarah Marlien, tells you all about contact lenses and wearing them at night.

When open, the eye receives oxygen from the ambient air. At night, when the eyelid is closed, our eye is therefore not oxygenated. We then wake up with natural edema, which disappears very quickly as soon as we open our eyes. The lens is an additional barrier that oxygen must cross to reach the cornea.

It is therefore important to know that it is not recommended to sleep with your contact lenses or colored lenses in order to ensure a good supply of oxygen to your eyes and to prevent maceration of microbes and bacteria. This is why it is essential to thoroughly clean and rinse your monthly or quarterly lenses with saline solution before putting them back in. Sleeping with contact lenses or colored lenses can have different effects upon waking: a red eye and, above all, a painful one upon waking.

Of course, you may find yourself falling asleep for a nap with your contact lenses or colored lenses in, or dozing off in the middle of a book... No worries. A thirty-minute nap will not affect your eyes.
On the other hand, if you fell asleep with your lenses in and realize it the next morning, here are some tips:

• Don't remove your contact lenses right away; they may have sucked on your eye a little...
• Put a few drops of saline solution or comfort drops in your eyes, blink your eyelids several times to rehydrate the entire surface.
• A few minutes after inserting the saline solution drops, you can gently remove your contact lenses so as not to damage the Cornea.
• It will then be recommended to wear your prescription glasses during the day to allow your eyes to breathe. If you experience any discomfort, discomfort, or the feeling that you cannot see clearly, it is recommended that you consult your ophthalmologist. If you're used to wearing silicone hydrogel lenses, you'll experience less discomfort than if you're used to wearing hydrogel lenses.

Don't hesitate to ask your optician or ophthalmologist for advice.

Night and Day contact lenses: contact lenses for nighttime wear

Do you tend to forget to remove your contact lenses or colored lenses? You can opt for Night and Day contact lenses, which are silicone hydrogel lenses with very high oxygen permeability. They can be worn for up to 15 days. On average, you can wear them for 6 consecutive nights. Ask a specialist for advice on contact lens wear. They will provide you with a personalized solution. It is still preferable to remove your lenses on weekends, for example, to allow your eye to retain all of its contact lens capacity and to tolerate longer lens wear. This will prevent you from developing lens intolerance at a certain age.

There is, however, one exception. These are contact lenses called Orthokeratology: these are lenses designed to correct myopia and mild astigmatism.

They are worn at night and removed during the day. At night, the lens acts on the shape of the cornea to allow you to see clearly without contact lenses during the day. This method has very good results because it can also stop the progression of myopia. This process is performed after a specific adaptation. Again, we recommend discussing this with your optician or ophthalmologist.

Take care of your eyes, respect the wearing times indicated for each contact lens model, and if you have any doubts, seek specialist advice.
