Often people with poor eyesight are faced with a situation where, in the evening or in the afternoon, those who are tired or captured by some thoughts fall asleep without removing their contact lenses. In this regard, readers have legitimate questions - someone slept in the lenses, and apparently, nothing happened to the eyes - so you can continue to sleep in them, ignoring the restrictions in the instructions. On the contrary, someone may experience panic and fear - what will happen to their eyes now.
So is it possible to sleep in contact lenses?
You are not the first or the last to accidentally fall asleep in contact lenses. And manufacturers of optics have long paid attention to this and offered the market several different types:
Daily wear lenses. This is the most common type. Such contact lenses can be worn only during the day and removed at night. This means that manufacturers do not make the design available for long-term wear. And since the basic requirements are an indicator of oxygen transmission and moisture retention, the person who wears lenses, accidentally fall asleep, after waking up, may encounter discomfort caused by poor oxygen supply to the eye tissue. Usually, it is a burning sensation, dryness, and redness of the eyes. In this case, it is necessary to clarify such a nuance as sleep in general, because a person can fall asleep not only at night, but also in the middle of the day. In this case, the key factor is not the time of day, but the physiology of sleep itself. Namely, in a dream, we close our eyes for a long time, and the eyelids significantly limit the access of oxygen to the cornea. That is, during the daytime sleep, the carrier may also exhibit symptoms of eye hypoxia.
The right attitude is important here - if you fell asleep like this once, then it is worth drawing the right conclusions from this and foreseeing that the next time this situation does not happen again. Regular falling asleep in improper lenses can lead to disease (neovascularization).
Flexible wearing lenses. In life, there are situations when you are away from home or far from a pharmacy or optics, and there is no other pair of lenses or solution with a container at hand. In this case, the lenses of the flexible mode of wearing can help out without delivering unpleasant consequences. More often, corrective means of this mode of wearing are a silicone-hydrogel type of material. These optical products have the best balance of oxygen permeability and hydrophilicity. But even with this type of lens, you should not spend more than two nights in a row.
Lenses of prolonged wearing. This is an improved combined type, so to speak when the lenses can be worn for six days in a row. Manufacturers took care in advance and provided their optical products with a safety margin.
Continuous wear lenses. Such products can be worn for up to thirty days without taking off day and night. After the expiration of the product, it is simply discarded. But even for such lenses, ophthalmologists recommend removing them at night every few days and putting them in a solution, giving the eyes a rest. During a visit to the doctor, you will be advised of the best wearing regime for you, taking into account all your features, which include:
- Lifestyle and working conditions;
- The degree of sensitivity of the cornea;
- A tendency to allergic eye reactions;
- Other ophthalmic restrictions.
As we already described above, daytime sleep is also undesirable if the contact lenses are not applicable to it. But if this still has happened, then immediately use moisturizing drops after waking up - such a solution will prevent the unpleasant consequences of temporary oxygen starvation. If daytime sleep is your soft spot, then think in advance about using the contact lenses of a prolonged mode of wearing.
If you fell asleep in tinted contact lenses?
It is not recommended to sleep in such lenses. The coloring enzyme contained in tinted contact lenses reduces oxygen transmission, so waking up in such lenses will be even more unpleasant than in other optical products that are not intended for continuous use. Most products even indicate a limited time of daytime use. But in any case, faced with a similar situation, it is necessary to quickly remove the lenses and instill multifunctional eye drops to reduce unpleasant consequences.
Can I sleep in rigid contact lenses?
If rigid lenses belong to the optics of daytime wearing, then it is not advisable to sleep with such lenses. An exception is orthokeratological lenses, which are specifically designed for night vision correction.
What are orthokeratological contact lenses?
These are special rigid lenses that are worn exactly at night and sleep in them. These lenses are prescribed by an ophthalmologist for the treatment of any visual pathology. During the night, they change the shape of the cornea or eyeball. A person spends the day without correction means, his eyes take on their original form during this time.
This correction method is especially suitable for children who do not like or, for some reason, cannot wear glasses or contact lenses during the day. For example, orthokeratological lenses can stop the progression of myopia. Night lenses are made individually, have contraindications and features of use, which your doctor will tell you about.
