Why do you have to wear sports sunglasses when running?

With the promotion and development of running, more and more running events follow, and more people join the running team. When it comes to running equipment, the first thing that comes to your mind must be running shoes. Next is running clothing, and professional runners may buy compression pants to protect themselves. However, the importance of sports glasses has been ignored by many runners.

If we do a questionnaire to runners, ask: Do you wear glasses when you run? I believe that the conclusion drawn is definitely not the majority. However, when participating in a marathon, you will still see many runners wearing glasses, which are cool and handsome in various styles and lens colors.

In fact, this is not to be cool, but to protect the eyes. It is important to know that our eyes are very easy to absorb ultraviolet rays from the sun, and direct sunlight outdoors for a long time will cause great damage to the eyes. Sports glasses can effectively block ultraviolet rays and avoid the stimulation of strong light.

Today, IVision will explain to you the importance of wearing sports glasses when running~

1. UV protection

Ultraviolet rays are part of the radiation from the sun, and also the most lethal part. We cannot observe the existence of ultraviolet rays with the naked eye. But it is with us day and night. Don't take it lightly because the sun is not strong and the weather is not hot on cloudy days. Ultraviolet rays actually exist 24 hours a day.

Our eyes are very easy to absorb ultraviolet rays from the sun, and long-term outdoor training or competition under direct sunlight will cause great damage to the eyes. UV damage builds up over time, and each exposure to sunlight on your eyes has a cumulative effect.

Ultraviolet rays should be absorbed by the lens in the eye. If the absorption is incomplete, it will enter the retina and cause macular degeneration. At the same time, if the absorption is incomplete, the lens will be clouded and serious eye diseases such as cataracts will occur. Chronic conjunctivitis, corneal damage, pterygium, glaucoma, and retinal damage may occur due to prolonged overexposure to UV rays

Although some people will say that a hat can block the sun, but after all, it is not close to the eyes in 360 degrees, and the effect is not as good as sunglasses. The high-tech anti-UV coating of professional sports sunglasses can filter 95% to 100% of UV rays.

2. Anti-glare light

In addition to ultraviolet rays, the strong light in the sun can cause severe irritation to the eyes. Studies have shown that the outdoor sunlight is as much as 25 times the indoor light. The sunglasses can soften and weaken the strong light, and provide a comfortable transition to the eyes when the outdoor light environment changes, ensuring smooth running. Outdoor athletes can improve visual clarity by wearing sunglasses.

When you suddenly enter a relatively dark environment from a long-term strong light environment, it will cause a short-term dizziness, or even blindness. Especially in the process of trail running, such an instantaneous change is quite scary. If you can't see the surrounding environment clearly and can't judge the foothold in time, it may cause danger in sports.

In addition to sunlight and ultraviolet rays, when light passes through uneven roads, water surfaces, etc., irregular diffuse reflection light is generated, commonly known as "glare". The appearance of glare will make human eyes uncomfortable, cause fatigue, and affect the clarity of vision. Strong glare can even block vision, adversely affecting the quality of vision, so as to affect the fun and safety of your running.

3. Prevent foreign objects from entering the eyes

Wear sports glasses when running, it will be your first line of defense to protect your eyes. It can not only help you block UV rays and glare, but also prevent eye irritation caused by strong winds during fast movements. At the same time, sports glasses can also prevent sand, flying insects and branches from causing damage to the eyes

Especially when running in summer, there are more flying insects in the morning and evening, and if you are not careful during the running process, they will get into your eyes, which will make people uncomfortable. Wearing glasses can effectively prevent foreign objects from entering the eyes. In the process of trail running, due to too much focus on road signs and road conditions, it is often difficult to notice the branches on both sides of the road, which often scratch the eyes.

The lenses of sports glasses have super impact resistance, and can ensure that the lenses will not be broken and cause secondary damage to the eyes in the event of accidental injury. Taking IVision sports sunglasses as an example, its excellent air vent design and anti-slip and breathable design of the nose pad can ensure that the frame does not loosen even when you are running fast and sweating a lot, avoiding the embarrassment of frequently holding the glasses. Get distracted by unwarranted distractions, so you can devote yourself to the running game.

4. Guarantee good dynamic vision

During running, the dynamic vision of the human eye to observe various conditions on the road and its surroundings is much lower than that at rest. As you run faster, your eyes work harder.

When the work intensity of the eyes is very high, the reduction of our vision will be relatively obvious, and the range that the eyes can see clearly will become narrower and narrower. Also, your visible vision and field of view worsen with increasing speed. If the eye and vision protection is not good, it is difficult to cope with various situations, and accidents are inevitable.

In the day or night, in different weather conditions and in different environments, the degree of light and shade changes constantly during the running process, which affects our vision at all times. We can respond to different weather environments by wearing spectacle lenses with different lens colors and types.

Alternatively, you can choose color-changing lenses, which can automatically adjust the light entering the eye at any time according to the environment, improve the comfort of the eyes, maintain a high visual sensitivity, and ensure clear vision. It is convenient and saves the trouble of changing lenses.

5. Prevent glasses from falling

I believe that many myopic friends have experienced the painful experience of myopic glasses jumping up and down the bridge of your nose when going for a run. After a marathon, the most likely hand movement is not wiping sweat, but "holding glasses".

How to solve the problem of glasses shaking, many people may have tried: wearing non-slip sleeves, glasses straps, and hoods, but these can only alleviate the problem temporarily, and cannot fundamentally solve the problem, and the aesthetics and comfort are more than a little poor.

The glasses are not worn firmly, and it has something to do with the design of the frame and temples and the nose pads. Sports glasses, especially professional sports optical glasses (which can support myopia customization).

Sports sunglasses also have some other professional sports properties, which may not be necessary for ordinary amateur runners, such as wind resistance, anti-fogging, discoloration and coating on lenses.
