Regrettably, only a few people have perfect vision . Since childhood, many have to wear glasses. But such an accessory is not to everyone's taste. A great alternative can be contact lenses. These devices for vision correction have recently gained enormous distribution. Both foreign and domestic manufacturers offer their products.
Kinds
Today on the market there are a huge number of contact lenses, which
differ in shape, purpose and material. All of them can be divided into hard and soft. Hard lenses are prescribed by a doctor in rare cases. But soft contact lenses of prolonged wearing are very popular not only among those people who suffer from visual impairment. With their help, you can change the color of the eyes.
By appointment, contact products for vision correction are divided into therapeutic, cosmetic and optical. One device can combine several purposes at once. So, contact lenses of prolonged wearing can not only correct vision, but also the appearance of the eye.
Also, all vision correction tools are divided into traditional and planned replacements. The lenses of the first type can be worn for a long time, and the second - you need to change several times a month.
How to choose contact lenses?
In order to offer one or another type of product, a specialist must first examine the patient's vision. An ophthalmologist can examine each eye separately, using special devices. The doctor should find out how much vision is reduced, in what condition the eye muscles are, whether intraocular pressure is increased. Only after a full examination can you choose contact lenses. The pros and cons of a particular model should be clarified before purchasing.
A very important indicator is the correct fit of the lenses on the eyes. Indeed, eyeballs in individual patients differ in shape and size. Before selecting a specific model, the ophthalmologist must measure the size of the eyeball with a special device.
Patients with increased dry eyes are recommended to choose contact lenses for scheduled or daily replacement. Traditional options are not suitable for patients with sensitive cornea. Drops when wearing contact lenses will also help relieve discomfort.
An ophthalmologist may suggest that the patient put on a test tube to make sure the lens is correctly matched. Sometimes, in order to choose a suitable option, you have to re-measure several pairs of products. It’s definitely hard to say which contact lenses are better . Reviews about individual manufacturers are very diverse. Selection should be done based on your own feelings during the fitting.
How to wear?
At first glance, it may seem that the use of contact lenses is a science. In fact, learning how to put on and take them off is quite simple. Most people can use the product correctly from the second try. Lenses can become an integral part of the eye.
Any products require a little time to fit. From the moment the lenses are installed, it can take up to 10 minutes before they cease to be felt at all. The ophthalmologist will provide accurate instructions for handling vision correction tools and tell you which drops to wear when wearing contact lenses. For reference, let’s say that the most popular drugs are Oksial, Khilo, Komod and others.
Dream use
Many patients wonder if lenses can be used during sleep. Most products intended for vision correction, suggest wearing only during wakefulness. This means that they should be worn in the morning and removed before bedtime. But on sale there are also more expensive models that can be used during sleep.
Experts still do not recommend using the product continuously. The eyes, like the whole body, should rest during a night's sleep. Prolonged wearing of vision correction devices without interruption can cause not only visual impairment, but also other complications requiring long-term treatment.
Benefits
For people who need constant correction of vision, contact lenses will be a real find. After all, glasses spoil the look. But the person who put on contact lenses is not so easy to identify. Such a device will come to the aid of girls who care about their own style.
Everyone should know how to choose contact lenses that are suitable not only for medical reasons, but also for color. After all, high-quality models can also make eye color more expressive or even change it.
Contact products for vision correction are very convenient to use. They can not be removed all day. This device is especially convenient during sports. If you have a swimming lesson, you will have to acquire additional special glasses.
In the summer, sunglasses can be worn over the lenses. So the vision will be at the right level, and facial wrinkles will not appear.
A bit about the flaws
Despite the fact that manufacturers offer comfortable and soft contact lenses, the cornea of the eye can still perceive the product as a foreign object. As a result of this, an allergic reaction may occur. If used improperly, it can seriously damage the eye.
All contact lenses pros and cons are completely different. Solid models practically do not pass oxygen. Violation of gas exchange can cause an inflammatory process in the eye.
A huge drawback is the cost of contact devices for vision correction. A quality product is quite expensive. In addition, any device will have to be replaced sooner or later. Before you purchase contact lenses, the pros and cons of a particular model should be checked with an ophthalmologist. You should use every opportunity not to overpay.
Use correctly
First of all, you need to remember that lenses are a medical device. Before using them, it is advisable to consult a specialist. Only proven models that have received the approval of specialists are worth buying. For example, Acuvue contact lenses are quite popular . Reviews about this manufacturer are only the most positive.
Before using the product, wash your hands well. Correctly store contact lenses. The pros and cons of using special solutions for lenses can be found out with an ophthalmologist.
The product must be used before the expiration date. Continued wearing may harm the eyes. For a night's sleep, lenses must be removed.
Soft products require special care. No drops should be dripped on them without the permission of the doctor. An exception may be only special drops that are designed to moisturize the eyes.
