What should athletes pay attention to when choosing sport glasses?

When choosing sunglasses for sports and outdoor activities, there are many things that it is important to know about so that the glasses fit properly on the face and provide proper protection. There are a lot of types in stores, but there is often not enough knowledge to choose the optimal one for specific tasks. Let's take a step-by-step look at the important characteristics of sports glasses.
1. Types of lenses.
The lenses protect the eyes from ultraviolet radiation. High-quality sports glasses don't pass all types of ultraviolet rays: A, B, C (although only the first two pose a potential danger to humans). This applies even to those lenses that have no blackout at all.
Darkening doesn't affect UV protection. Tinting lenses prevents the passage of part of the visible spectrum of light and is necessary for the eyes to be comfortable in bright sunlight. Almost all Torege's sunglasses have Complete full-spectrum UV protection, including UVA, UVB, and UV400 wavelengths.
Also, sports optics protects against a branch or a pebble that has flown into the eyes, jumped out from under the wheel of a passing car. All sports glasses with polymer-based lenses cope well with these tasks.
2. About the optical properties of lenses
At first glance, all sunglasses seem similar, and a lot of people do not understand why they should pay more if the cheapest glasses also save from UV radiation and direct sunlight. And here it is worth noting that brands specializing in the development of optics focus on the development of technologies to improve the quality of lenses. If you plan to wear glasses for no more than half an hour a day on a regular walk, the optical properties of lenses are not so important, but if glasses are chosen for long-term use and sports tasks, then you need to pay close attention to the choice of high-quality glasses.
Optical correctness.
Any lens somehow distorts the image, but the greater this distortion, the more tired the eyes become. In sports where you need to constantly monitor the changing environment: mountain biking, trail running, kayaking, the optical correctness of glasses affects the safety of the athlete. Torege uses a special TORIEX material that provides better visibility during any sports activity.
Contrast.
Lenses with different light filters — colored pigments in the material or colored coatings - can highlight the weakest scattered parts of the spectrum: yellow, orange, pink. This is how filters emphasize the surrounding environment: terrain details or other objects.
Polarization.
Removes glare from reflected light, which can dazzle more than direct sunlight. This is especially evident on wet asphalt, water, and in the mountains, during exits to a glacier or a snow-covered pass. Because of the glare, it is difficult to see the terrain, and the eyes water and get tired quickly. On the water, glare prevents you from seeing the bottom relief.
3. What are sports glasses lenses made of?
Made of polycarbonate. It is a lightweight, flexible and durable material. Lenses made of it protect the eyes not only from bright sunlight and UV rays but also from mechanical damage, for example from small stones. The advantages of polycarbonate lenses are low price and weight.
Made of polymer NXT. These lenses are much more expensive than polycarbonate ones.
4. What are the lenses covered with?
The properties of sports glasses lenses can be improved if they are coated with special compounds. They are applied to most of the top-class glasses. Here are the most popular:
- oleophobic coating simplifies the cleaning of lenses from dirt and fatty secretions of human skin;
anti-fog reduces the risk of fogging glasses;
- the water-repellent composition causes water droplets to roll off the lens surface, improving visibility, can be applied both on the outer wall of the lens and on both sides of it;
- a mirror coating is used to darken and dim glare in non-polarized lenses.
5. Types of frames of sports glasses.
There are many types and types of frames. They differ in geometry, the distance from the shackle to the shackle and between the lenses, the degree of fit, the width of the bridge of the nose, the tilt of the lenses, the degree of bending. But these parameters are usually not taken into account when choosing glasses, for buyers they are a formality because no one measures the exact dimensions of the face and head. We talk about popular characteristics that will help narrow down the list of suitable models.
6. What are the frames of sports glasses made of
Nylon is the most popular material in the frames of sports glasses. It is lightweight, flexible, durable, and cheap to manufacture.
Elastomer is used as inserts that absorb moisture. They allow the glasses to hold on better during sweating under intense exertion or high temperature. The frame with inserts does not slip and does not rub the skin.
7. Mechanisms in frames
Lens change mechanism. It helps to put lenses with a different category of dimming or filter if the weather conditions or time of day have changed. It is implemented differently by different manufacturers, but most often it is a simple mechanical lever on the rim. Torege has a collection of sunglasses with interchangeable lenses.
