Those who use contact lenses should be especially careful about the likelihood of chronic and infectious inflammatory eye diseases. Each variety of products is distinguished by its established regime and the period of possible wear. Observing these rules, you can get the highest reliability of eye protection. And in this article we will talk about how much one-day lenses can be worn.
What threatens non-compliance with the duration of the use of lenses
If the contact products are not replaced on time, then there is a possibility of a mass of adverse consequences:
- During the wearing of lenses, protein and lipid layers may appear on them (the glass ceases to be clean). If the operating procedure is systematically violated, and the lens is used longer than the established period, then the possibility of infection penetration increases significantly.
- Over time, irreversible deterioration of the material from which 1-day 1-day lenses are made, for example, occurs. This means that you can wear products with such a period of no more than a day, as the material after 24 hours becomes unusable.
- An important factor is that the ocular cornea often suffers from a constant lack of oxygen, if the lenses are used for a sufficiently long period. Such a disease is called hypoxia, all kinds of damage can occur, as well as complete loss of vision.
Any type of contact lens is made from a raw material that has a different oxygen throughput. In this regard, each type has its own modes and terms of safe operation.
Can I use at night?
One-day lenses (the price of which varies between 2000 rubles), according to most qualified ophthalmologists, benefit the patient precisely in the daytime. It’s better not to wear them at night. However, there are many cases where the use of products is required just at night. For example, such "clothes" for the eyes are needed for elderly people and children who are not easy to take off and put on all the time, working night shifts, or for those who prefer to go to night schools.
In nature or on a hike, it is also not always possible to change lenses in a suitable environment. To make it comfortable to wear, and eye health not to deteriorate, you need to sign up with an ophthalmologist so that he correctly helps determine the timing and mode of use.
How much can one day lenses wear
Lenses can be used no more than a day. In the morning they should be worn, and in the evening they should be removed, and then thrown away. Daily products are the most reliable, because they are not processed by any means, but always put on sterile. That is why comfort and clarity of vision in them are maximum.
However, one-day lenses also have the disadvantage - their price is very high. And despite this, many people simply can not not wear them. For example, those patients who are allergic to cleaning products, or those who rarely use contact lenses. The manufacturer produces 30 blisters per pack.
On a note
Any person with low vision should be sure to observe all the terms of wearing lenses with all responsibility and seriousness. Products are provided for a specific period, and this does not depend on the number of donings. If the patient violates the regime, this will adversely affect the health of the eyes.
Acuvue Moist Lenses
They relate to daily change products, are intended for daily use and can be used by patients with great eye sensitivity. The maximum degree of moisture significantly reduces the risk of ocular “dryness”. Acuvue Moist one-day lenses can be worn all day.
An ultraviolet filter is used in products for special eye protection. It is also necessary to take into account the fact that one-day Acuvue Moist lenses do not cover the entire eye, so when you are in the sun for a long time, you need to use sunglasses. Still such products are ideal for those who suffer from allergies.
Their advantages
This kind of lens has many advantages, such as:
- lack of lipid and protein layers;
- high definition of vision;
- the presence of ultraviolet protection;
- wearing comfort;
- good oxygen transmission;
- the ability to freely lead an active way of life, as well as play sports;
- suitable for patients with allergies;
- no problems with the container and special care for the products.
How much can one day colored lenses be worn
Such products are slightly different from corrective ones. Due to their softness, oxygen intake to the ocular cornea is reduced. With prolonged use, this leads to redness and pain in the eyes. In addition, there are also matte multi-colored lenses (disco). They make it difficult to perceive tones and, with constant and incorrect use, can impair vision.
To avoid unpleasant symptoms, you should adhere to the terms of use of these lenses (4-5 hours per day). If there are signs such as fog in the eyes, or tingling, then you need to immediately remove the product. It is also unacceptable to sleep with colored lenses, as this can lead to oxygen deficiency of the iris. It is also important to comply with the requirements for the care of products, not to use them after the expiration of the term. After all, many probably already understand how much one-day lenses can be worn.
How to apply them
You need to get used to using the products little by little: start wearing 1 hour per day, and then increase the time by 30 minutes daily. In case of discomfort, it is necessary to remove the lenses, give the eyes a rest.
For any person, the wearing period is individual and is determined by the sensitivity of the eyes. If after removing the products a gray haze is visible before the eyes, and this sensation will not pass for 15-20 minutes, then the service life has been exceeded. However, if after 5 hours of using the lenses there were no discomfort, then you can wear them longer.
It is forbidden to use products if there is a bacterial infection, conjunctivitis, demodicosis, exacerbations of blepharitis and much more. How many day lenses you can wear, now you know.
