contact lenses

Contact lenses are the inconspicuous alternative to glasses. Nobody sees that a vision aid is needed and the spectacle frame does not disturb the face. More and more people wear contact lenses and are satisfied with them. The selection is getting bigger and bigger here. Since there are different types of lenses, each wearer must find the right lens for them. Here the opticians advise but also on the Internet there is a large selection.

Determining visual acuity

Do you notice that your eyes get worse and you have problems seeing? Then you should first visit an ophthalmologist or optician and have them examine you. It must be determined exactly whether you are short-sighted or farsighted. Many people also have astigmatism. The exact values are determined using state-of-the-art technology. You will get these on a small card called a glasses pass. The document is also called this way if you are only interested in contact lenses.
If you know your values, you have the choice of ordering your contact lenses from an optician or looking for them on the Internet. For the first time, however, we recommend that you order from your optician, who will show you how to insert your new contact lenses into your eye and remove them again. He will also give you tips and advice for everyday life and use.

What types of contact lenses are there?

On the one hand there are the so-called soft lenses. The size of these covers the entire cornea. The supply of oxygen to the eye takes place easily through the very thin lenses. The lenses are available with a shelf life of one day, one month or even a whole year. Your eye needs a few hours to a few days to get used to the contact lenses. They are cheap in price. These contact lenses have a good hold on your eye and slip not.
Both of these hard contact lenses are a dimensionally stable material; they are actually rather hard in handling. They lie only in the middle of the cornea and are significantly smaller than the soft lenses. The hard lenses do not allow oxygen directly to the eye. This is supplied with oxygen by the tear film. In terms of acquisition costs, hard contact lenses are more expensive, but also last longer. Because the hard contact lenses are smaller, they sit looser on the eye than the switches.

Daily, weekly, monthly and annual lenses

Daily disposable lenses are especially suitable for you if you only want to wear contact lenses from time to time. Remove these lenses fresh from the packaging in the morning and dispose of them in the evening. Therefore no care product is necessary and there is no risk of infection. Daily lenses are always soft lenses.
Weekly lenses can be used for up to two weeks. The respective manufacturer provides information on how long the lenses should actually be used. Weekly lenses must be cleaned daily with a special care product. They also belong to the soft lenses.
You can use the monthly lenses daily for a whole month. These must be cleaned daily very conscientiously. Deposits of any kind must have no chance. These contact lenses are very suitable to be worn daily.
Annual lenses can be worn for up to 1.5 years. To ensure that the annual lenses last at least one year, they should be cared for particularly conscientiously.

How are contact lenses maintained?

Your contact lenses must be taken care of every day if they are not daily disposable lenses.
The best thing to do is to put your contact lens care system together in such a way that you can cope well with it. If you have any allergies you must be particularly careful and should inform the optician of this.
In the first step, the contact lenses are cleaned in a special liquid. To put them in and remove them easily, use a special pair of tweezers. Please do not take tweezers from your household as they can scratch the lenses. After cleaning, clean the contact lenses with a saline solution (NaCl). Afterwards they have to be disinfected in order to prevent germs and bacteria from getting a chance.
From Fielmann, for example, there is now a solution with which all processes can be completed in one go. This is slightly more expensive than the individual chemicals, only one process is necessary for the contact lenses.

Cleaning step by step

Cleaning your contact lenses is an important process. Your eyes must be spared and the lenses should be as durable as possible. It is important that none of the detergents get into your eyes. The process must therefore be carried out carefully and very carefully.
The first step is surface cleaning. This removes grease residues and other dirt from the contact lenses. The lenses are carefully rubbed back and forth between the fingertips with the agent. The pressure must not be too strong for the contact lenses to remain intact. If cosmetic residue has got on the contact lenses, these are also removed during the process. As there are different cleaning agents, the components are printed on the respective packaging.
In the second step, the contact lenses are rinsed with NaCl. This will remove the cleaner. Under no circumstances may tap water be used for this process. The saline solution, on the other hand, is suitable for all types of contact lenses.
The third step is the disinfection of the contact lenses. Here are Bacteria and other substances carefully removed. If you are allergic, we recommend a peroxide solution that really kills all substances.
If your eyes are not particularly sensitive, you can also use the combination solution. This unites all individual steps in one solution.

Storage of contact lenses

If you remove the lenses from the eye in the evening, please do not place them on the bedside table or any other surface. This could cause dirt particles and dust to come into contact with the lenses or, in the worst case, damage and scratch them. Place the contact lenses in a storage solution that you can get from your optician or on the Internet. This solution ensures that the lenses really remain disinfected until the next use. The lenses are thus protected from pathogens. At the same time, the wettability of the lenses is maintained by the solution.
If you notice that despite cleaning and careful storage there is still a veil or film of dirt on your contact lenses, there are special cleaning tablets available. These work with the help of enzymes and can remove proteins. Unfortunately, proteins cannot be removed with normal care. However, only use this option if you notice that the lenses require additional cleaning.
