In the previous article, we discussed “When did sunglasses become popular?”. In this article, let’s talk about “Why Should I Wear Sports Sunglasses When Playing Sports?”.
What are the benefits of sports sunglasses?
Our eyes are very easy to absorb ultraviolet rays from the sun, and long hours of outdoor training or competition under direct sunlight will do great damage to our eyes. Chronic overexposure to UV rays can lead to chronic conjunctivitis, corneal injury, pterygium, glaucoma, and retinal damage. High-tech anti-UV coatings on professional sports sunglasses can filter 95% to 0% of UV rays. In addition to ultraviolet light, the strong rays of the sun can cause severe irritation to the eyes. Studies show that the sun shines 25 times as brightly outdoors as it does indoors. Sunglasses, on the other hand, can soften and weaken bright light. The lenses of sports sunglasses are shock-resistant and ensure that they don't break and cause secondary damage in the event of an accident.
How to choose sports sunglasses?
The first type is for summer use, the sunglasses for this use should be lightweight, breathable, and of moderate size. The frames can be made of plastic or metal, but polarizing lenses, also known as polarized lenses, are best for dealing with glare. The second type is for winter use, which mainly aims to deal with the ultraviolet reflection from the snow, preventing snow blindness. Snow belongs to diffuse reflection, so the light has no direction, so you should try to choose large lenses, preferably with side skin lenses and the eyes as far as possible completely wrapped. The third type for use is driving or riding, at this time the glasses should not be too large. The polarized lens can prevent the glare of the opposite car headlights, or glare from the building of metal, glass, and other strong reflections. The lens color must be as light as possible, and the light transmittance effect must be better.
What's the price range for sports sunglasses?
The main difference between sports glasses and ordinary glasses is the shape. The specific price depends on the craft and material of each brand and a single pair of glasses. The price of different brands is different because the lenses of sports sunglasses are made of special materials and processed through special processes. The price of sports sunglasses with different lens materials is different. Magnesium alloy lenses are characterized by soft texture and generally won't deform. The price of sports glasses made of this kind of material is relatively high, usually about 00 yuan per pair. PC lens sports glasses are also a kind of sports glasses on the market, using common material, with characteristics that it is not easy to break. The price is 1200 yuan; Ordinary sports glasses are very cheap, it is 0-400 yuan or so, but their safety is lower.
