Many people with long experience wearing glasses are considering changing their lenses. However, this is a whole science. Read how to choose contact lenses below.
First of all, it is necessary to visit a specialist, because to know only an indicator of myopia or farsightedness is not enough. An ophthalmologist will take all necessary measurements and determine the individual characteristics of your eyes: microflora, tear fluid composition, corneal sensitivity and much more. Clearly and accurately answer the doctor’s questions, because you can choose contact lenses for the eyes only after all the details have been clarified, right down to the general state of your health and the features of your work. You can use the services of cabinets located in many optical stores.
Eye contact lenses are hard and soft. Most people prefer the latter.
How to choose contact lenses: softness and rigidity
Soft are divided into:
- Low hydrophilic - less than half the moisture content. They are more durable, less prone to damage.
- Highly hydrophilic - more than half the moisture content. Less durable, they accumulate protein deposits faster.
Soft lenses can be changed both rarely and often. The former must be washed in a special solution, and the latter should be discarded immediately after use.
Soft lenses are easy to use. With the right parameters, they are not felt. However, they also have a negative side. A large number of pores can contribute to the development of microorganisms.
Hard lenses are prescribed for people with eye diseases. They perform both a healing 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.
Hard lenses are removed after a thorough study of the patient’s eye features. Their stiffness can be different, and it should be chosen based on the stiffness of the human cornea.
How much do eye lenses cost
Their price can be very different. For example, you can buy a set of lenses that you rarely need to change, for an average of 300 rubles. In addition, you will need a solution worth 200 rubles. Prices are approximate, and it is important to consider what prescription your doctor will prescribe. The main thing to remember is that too low a cost, as a rule, also indicates a low quality of the goods.
It is worth noting that everyone chooses an option convenient for him. Lenses that should be changed daily are more expensive at a cost. But for an option with a rare change, care is very important to prevent the growth 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 allow light to pass through well, so you need to change them to transparent ones before driving, for example.
In addition, doctors recommend wearing lenses for 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 consider the price. Health to you!
