Learn how to choose contact lenses

Many people who have a long experience in wearing glasses, are thinking about changing them to lenses. However, this is a whole science. On how to choose contact lenses, read below.

First of all, it is necessary to visit a specialist, because knowing only the indicator of myopia or hyperopia is not enough. The ophthalmologist will make all the necessary measurements and determine the individual characteristics of your eyes: microflora, the composition of the tear fluid, the sensitivity of the cornea and much more. Clearly and precisely answer the questions of the doctor, because you can choose contact lenses for the eyes only after finding out all the details - up to the general state of your health and the features of your work. You can use the services of the offices, which are in many shops of optics.

Contact lenses for the eyes are hard and soft. Most people prefer the latter.

How to choose contact lenses: softness and stiffness

Soft are subdivided into:

• Low hydrophilic - less than half the moisture content. They are more durable, less prone to damage.
• High hydrophilic - more than half the moisture content. Less durable, they accumulate protein deposits faster.

Soft lenses can be changed as rarely, and often. The first need to be washed in a special solution, and the second - to throw out immediately after use.

Soft lenses are easy to use. With properly selected parameters, they are not felt. However, they also have a negative side. A large number of pores can contribute to the development of microorganisms.

Rigid lenses are prescribed to people with eye diseases. They perform both a therapeutic function and a vision correction function. They are not very convenient and quite noticeable, but they have no pores, and therefore access to various microorganisms is closed.

Rigid lenses are taken after a thorough examination of the features of the patient's eyes. Their stiffness is different, and it should be chosen based on the rigidity of the human cornea.

How much are the lenses for the eyes

Their price can be very different. For example, you can buy a set of lenses that you rarely need to change, on average for 300 rubles. In addition, you need a solution worth 200 rubles. The prices are approximate, and it is important to consider which prescription the doctor will write to you. The main thing that is worth remembering is that the too low cost, as a rule, speaks about the low quality of the goods.

It is worth noting that everyone chooses an option that is convenient for him. Lenses, which should be changed daily, are more expensive at cost. But for the variant with a rare change, care is very important in order to prevent the reproduction of microbes.

Contact lenses for the eyes can perform not only a corrective or therapeutic function. Masquerade and color will help change the image. However, it is important to know that they do not pass light well, so you need to change them to transparent before you get behind the wheel of the car, for example.

In addition, doctors recommend wearing lenses no longer than 4 hours, be sure to remove them at night and sometimes give your eyes a rest for several days - at this time you can wear glasses.

Now you know how to choose contact lenses. Think about quality, but also consider the price. Health to you!
