Sports glasses are an integral part of the inventory of all people leading a healthy lifestyle. Manufacturers improve models every year, using more modern and durable materials, improving lenses, creating more comfortable and practical designs. As in everything, it is important to choose a suitable model for yourself and your sport.
Varieties of sports glasses
Sun-protective sports glasses - have a darkening of one degree or another. There are more universal models for sports within the city (sports glasses for running, cycling, climbing and the like) and specialized ones for recreation in special conditions. For example, for trips to the mountains or to the desert, glasses with strong dimming are needed. This parameter determines the light absorption and light transmittance of the lens. The last criterion is usually indicated on a special sticker, arches or a label. There are five categories:
- 0 - almost transparent or barely darkened lenses, which almost completely pass sunlight;
- 1 - from 43 to 80% - light blackout;
- 2 - transmittance of light is equal to 18 - 43% - average level;
- 3 - the sun penetrates only 8 - 18%;
- 4 - practically non-transmissive lenses - less than 8%.
Lens Color
This parameter is not a manifestation of taste and style, but a factor dictated by external conditions and circumstances:
- For tennis lessons, choose sports glasses with blue or green lenses. They will enhance the contrast of the yellow sword against the background of the field.
- For golf, you are best suited for copper lenses - these will give the depth of the image and help to see the white ball in bright light.
- Also, amber lens range is recommended for cyclists and hunters. Mirror coating on such sports glasses will reduce the light reflection. In general, the entire yellow range is good in low light conditions (twilight, fog, clouds).
- When practicing water sports polarizing lenses are also ideal - their main task is to maximally neutralize the glare reflected from the water.
- Favorite by many gray scale has earned recognition not just because - lenses of this color give the maximum naturalness of lighting. They only neutralize the bright light, without distorting the color perception.
- Fans of winter sports, as a rule, choose sports sunglasses with orange or brown lenses. To better see the snow covered terrain in cloudy weather, choose orange tones, and for a bright sunny day, the best sports glasses are brown. To reduce the amount of light reflected from the snow will help mirror coating.
- And, finally, iridescent mirror lenses, the favorites of many, have the ability to soften the impact of bright sunlight on our eyes. They increase the contrast of the image, giving the opportunity to fully enjoy the scenery.
Sports sunglasses with diopters . Despite all the development of modern technology, existing sports glasses can not fully perform the function of corrective eyesight. The fact is that most models for outdoor activities are made with a strongly curved lens, and the production of diopters works mainly with "flat" surfaces. In addition, optical correction with a large curvature is not the best choice, since a highly distorted image can only exacerbate vision problems, triggering a prismatic effect and astigmatism .
Features of sports glasses
Of particular importance are the materials from which the model is made. They should be as strong as possible, but light. The latest development - carbon fiber products, which is 10 times stronger and at the same time 75% lighter than steel. Trying and picking up your own glasses, pay attention to their landing. Quality glasses have adjustable temples, allowing you to choose the perfect fixation, depending on the size and shape of the head. One more point - nasal stops. With active pastime and abundant perspiration, they should not rub, glide or interfere with you. Many people immediately buy sports glasses on an elastic band - they are worn as usual, but in a certain situation it is easy, convenient and, most importantly, securely fixed on the head.
