Sunglasses with diopters: description, types, models and reviews

With the advent of the summer season, when solar activity achieves maximum heat and light energy, ophthalmologists often have to remind their patients that they can not only protect their eyes from light, but at the same time maintain good visibility, which can be corrected in the usual way - with the help of Diopters.

Not protected from direct sunlight with high activity of light energy, the eyes are exposed to almost the same light burns as the skin. Sunglasses, greatly weakening the light flux, protect the optic nerve, mucous membrane and vessels, which are practically defenseless in bright sunlight. People who had visual acuity problems faced a choice: protect and protect their eyes or endanger them and use ordinary glasses with diopters.

Glasses for protection from the sun with diopters

Thanks to the latest technical possibilities, the problem of combining ordinary sunglasses with the possibility of correction of vision was completely solved. Virtually every polyclinic or health center, where optics is available, you can buy sunglasses with diopters. They will protect themselves from harmful sun rays, while the visual acuity will remain at the proper level. To buy such a product is best at specialized points of sale. Buying on the market does not guarantee the quality of the product, which is dangerous for the health of the eyes.

On sunglasses with diopters, prices can be different. It all depends on the quality of the products, the manufacturer (known or unknown brand) and other features. The cost of the most budgetary models averages between 600 and 1500 rubles. But before you buy the product, you must first pass a survey with a specialist.

Advantages of sunscreen optics with diopters

As time has shown, many patients who use sunglasses with diopters are very happy with the acquisition. The ability to clearly see objects and at the same time fully protect their eyes from direct sunlight solves the problem of proper rest and work in open spaces. Manufacturers were able to diversify products of this category, and to date there are the following options for sunglasses with eye correction:

• Sunglasses with diopters for drivers.
• Models for swimming.
• Models for sports.
• Glasses for children.
• Sunglasses with diopters for rest and work.

It is very important that some of the models not only perform their immediate protective function, but at the same time maintain the necessary visual acuity.

Features of choice

Diagnostics in special institutions will help determine the choice of the desired model. It should be remembered that sunglasses with diopters can differ in some functional features. For example, chameleon glasses with a brighter light change the color of the glasses, sealing the tint, thereby automatically adjusting the level of protection of the eyeball. In poor lighting, the optics become transparent again, thereby increasing the flow of light to the iris of the eye, which prevents the overstrain of the optic nerve.

The most basic criterion in the diagnosis of vision is the definition of visual acuity. Based on the results obtained, the necessary optics are selected. What is very important: the eyesight of the left and right eyes can have different parameters, in this case the lenses with the necessary diopters should be ordered individually.

Optical parameters to be taken into account

In any case, before you buy sunglasses with diopters, you need to pay attention to the following points:

• Manufacturer. The more known the manufacturer, the higher the quality of the lens and frame.
• It is mandatory to try on and try out the proposed model.
• Anti-reflective coating on lenses, which is the main protection against the invasion of the ultraviolet rays on the retina, is an indispensable condition for such models.

A poor coating layer or lack of it as such, a fuzzy blurry picture with loss of color shades indicates a low quality of the product.

Glass or plastic

The fact that plastic lenses compete for a long time in quality with glass is well known. Undoubted advantage of transparent plastic is the ability to withstand mechanical shocks during operation - they are difficult to break. But there are also minuses, which the manufacturer of this kind of optics does not advertise.

• During operation, plastic is covered with small cracks, scratches.
• Over time, the surface of the material deforms and becomes turbid.
• Despite the relative cheapness, plastic is short-lived for high-quality operation.

On sale there is also a good quality optics, made of plastic, which does not deteriorate for a long time and does not distort images, but, as a rule, this product is manufactured only by a well-known manufacturer and costs a lot of money.

Glass lenses are much higher in quality than plastic models. A well-focused glass transfers the picture to the retina of the eye 1: 1, this is the main superiority of the material.

The disadvantages of glass lenses can be attributed only two points:

• Damage caused by mechanical shocks.
• A high percentage of fogging after a sharp change of environment from cold to warm.

Ophthalmologists, advising their patients, give preference to glass lenses, since they are more qualitative.

Frames

Choosing frames, many in the first place pay attention to design and style. In addition, when choosing a frame, you need to carefully inspect the material from which it is made. The frame should not rub and press, cause irritation of skin areas where there is constant contact. Models with rubberized handles and silicone partitions sit comfortably and firmly on the bridge of the nose, without causing any irritation or damage to the skin.

Men's sunglasses with diopters

According to the design of the frames, the optics are divided into three types. Therefore, one of the popular themes from manufacturers are men's sunglasses with diopters, which are a true helper not only in everyday life, but also at work. A number of men's jobs involve working outdoors under the sun, including builders, road handlers, drivers, farmers and others. Many of them have vision problems, so their eyes need special protection. Thanks to the latest technology, it became possible to use sun shields for glasses with dioptries when driving cars, during rest and while playing sports.

When the lenses are sprayed, different levels of toning are used, with different density and the ability to pass sun rays onto the retina of the eye. There are 4 levels of coverage:

• "0" - 20% protection against exposure to sunlight. Sphere of application - office cabinets and places with small or unstable impact of sunlight.
• "1" and "2" - the best option for use in everyday life. Eye protection from exposure to sunlight from 20 to 80%.
• "3" - at least 90% of the eye protection from sunlight. The best option for relaxing on the beach.
• "4" - the strongest level of protection, is used by professional mountaineers and travelers in countries with high solar activity.

The photochromic elements used to cover the lenses are one of the newest discoveries in the scientific world that solved the problem of protecting the eyes from bright light and sun rays with additional correction of vision and bringing it back to normal for people suffering from visual impairment.
