Contact lenses have firmly entered our lives. Worldwide, more than 100 million people use them to correct vision. This is not surprising, because unlike glasses, they do not narrow the viewing width, do not limit a person's motor activity (he can even play sports) and are invisible. With myopia, hyperopia, astigmatism and other visual impairments, they are used by most people.
Recently began to wear and decorative designs. With their help, you can enhance or change the natural color of the eyes and achieve an amazing effect.
Contact lenses can be successfully alternated with wearing glasses. Caring for them does not take much time. When choosing this way of vision correction, there are no problems with the use of cosmetics. Contact lenses allow you to lead an active lifestyle in all respects. One-day contact lenses are especially good for athletes (which are better - we will consider further). With them you can wear sunglasses, 3D glasses or other equipment.
Lens selection
In order to choose a method of vision correction, you must consult a doctor. Only he can choose the model you need. The doctor will recommend the most comfortable and safe samples. Which lenses are better, one-day or two-week? This is not the only question that arises when choosing. What are the best day lenses? We will try to answer some questions, but we warn you: do not postpone a visit to a specialist, do not choose models yourself.
Types of Contact Lenses
Samples differ in the material from which they are made (hard, soft), in shape (flat, conical, etc.) and other parameters.
Particular attention when choosing a means of vision correction is given to the time of replacing the used pair with a new one. Existing models are divided into several types:
- One day. The recommended period of use is up to 24 hours. After that, the lenses need to be replaced. The next day they are not recommended for use.
- Planned replacement. The recommended period of use is up to 2 weeks. At night they are placed in a container filled with a special solution, after which they can be used again.
- Monthly replacement. Dispose of after 30 days of use.
- Traditional. The term of operation is more than a month (3-6 months).
This parameter is very important and directly affects the health of the eyes.
What happens to the lens with prolonged use
The lens as a foreign object, being on the surface of the eye, must be in perfect condition. This concerns its integrity (to exclude injuries), cleanliness (complete sterility) and the absence of plaque. The more a particular lens is used, the more likely it is to violate one or more of the above conditions and the appearance of complications.
After using the same lens for more than a month, an invisible coating forms on it. Proteins and fats stick to the surface, change the transparency of the lens, serve as a breeding ground for microorganisms and cause allergic reactions. That is why for such models there is a need for additional care (enzymatic treatment, disinfection). They must be thoroughly cleaned daily. Solution components may also bind to plaque and aggravate the situation. Ophthalmic complications are also caused by a decrease in the hydrophilicity of the lens and the sensation of sand in the eyes.
Confirmation of reduced security with extended use
The evidence is a significant reduction in infectious and allergic complications in the transition from traditional lenses to models with planned replacement.
This effect is reflected in the results of numerous medical studies. Obtaining confirmation of a decrease in the safety of contact lenses with an increase in the period of their use has led to an increase in the production of models by optical companies to 14 days. Saving on traditional samples also fails due to increased costs for containers, disinfectants and enzymatic agents.
Therefore, the question of which lenses are better, one-day or monthly, the answer is unequivocal - one-day.
What to choose: scheduled replacement lenses or disposable?
Which lenses are better, one-day or two-week? To answer this question, it is necessary to understand that the difference in these samples is not only in the duration of application of a particular model.
To maintain the lenses in perfect condition for 14 days (smooth, clean, without deposits), you need to take care of them. Every day after removing the lens with clean, dry hands, rinse it off the mucus with a fresh solution. When using solutions containing peroxide, carry out neutralization. Then place the lenses in a clean container (separate for each lens), pour fresh fresh universal solution.
In order to maintain a one-day lens, it is necessary to install it with clean, dry hands and also remove it at the end of the day.
The doctor can tell you which lenses are better (one-day or two-week) for you. Is it more convenient? Definitely disposable.
Characteristics of one-day contact lenses
Which one-day lenses are best preferred at the moment, can be decided at a consultation appointment. As a rule, the optometrist recommends models suitable for a particular patient. We will figure out what you need to pay attention to when deciding which one-day lenses are the best.
These vision aids can be made from hydrogel or silicone hydrogel. The latter is more modern and is produced by a small number of manufacturing companies. The answer to the question of which one-day lenses are better depending on the material will lead the cup of choice to silicone-hydrogel models.
Permeability to oxygen will also characterize one-day contact lenses. Which is better to choose? The more oxygen enters the cornea, the more favorable the prognosis. Therefore, when deciding which one-day lenses are better, the choice will tend to samples with the highest oxygen permeability.
One of the most important characteristics of contact lenses will be the moisture content. The desire of some patients to use hydrogel lenses with the maximum values of this parameter is erroneous. The higher it is, the more the eye dries. Which one-day lenses are best for moisture content? Hydrogel with a moisture level of about 50%, and silicone-hydrogel with a maximum moisture content.
Reviews of doctors and patients
Understanding that it is preferable to use one-day contact lenses, I want to choose the best of them. Patients and doctors share their experiences. Which one-day lenses are better? Reviews on numerous forums recommend one or another model to use. Most of them are united in the following:
- The presence of correctly selected lenses makes it possible to see the world in full.
- Contact lenses are a modern and very high-quality product.
- Using lenses for one day is the best choice for an active lifestyle, they save a lot of time.
- The implementation of the minimum recommendations does not entail complications and adverse reactions.
Buyers also recommend Akuview lenses (this manufacturer takes the top places in the ranking of the best means for improving vision). One cannot but mention the American company Johnson & Johnson. Their products are distributed in more than 175 countries.
Among Russian manufacturers, one can distinguish the company Concor and Doctor Optic. They produce soft contact lenses with different lifespan.
