For office workers who sit in the office for a long time during the day, running is a simple exercise for fitness and relaxation. Office workers mostly use night

running because they need to work during the day. But for myopic runners, vision problems when running at night are indeed a big problem. Most runners still wear

ordinary glasses or contact lenses directly while running, while a small number of runners will wear contact lenses + ordinary sports glasses. For running, the above

method is not desirable. Contact lenses are easy to dry and crack after a long period of wind, and even cause physical damage to the cornea.

Long-term or continuous wearing of contact lenses may keep the cornea in a state of continuous hypoxia, which will cause corneal epithelial edema and erosion. If

bacteria or viruses exist, it may lead to keratitis and even corneal ulcers. "

However, ordinary glasses have low safety performance of their frames and lenses, lack of protective performance of the lenses, unstable frame design, easy to loosen

when running, etc., and are more likely to slip when sweating, which is very impractical. This is where sports glasses come in.

What is the difference between sports glasses and oval sunglasses mens?

1. The lens color is lighter - to avoid visual disturbance

Generally speaking, the color of the lenses of sunglasses is darker than that of sports glasses. When exercising, it will cause visual confusion and cause greater damage to the eyes. Dark glasses not only make our vision darker, but also make the pupils bigger. The more ultraviolet rays that pass through the pupil area, the wider the range of damage to the lens and retina, which can easily induce glaucoma and cataracts.

Sports glasses can absorb a certain amount of infrared rays and ultraviolet rays through different lens colors. Can be very effective in reducing light intensity.

2. Non-slip nose pads and temples - more secure fit

The nose pads and temples of sports glasses are made of soft rubber pads, which fit the pinch points of our skin, and can play a good role in fixing during sports. Even if there is sweat or rain on the skin, it can also play a non-slip effect, so you don't have to keep holding it because of the shaking of the frame. The nose pads of ordinary sunglasses are integrated, which may not be suitable for everyone's nose bridge.

3. Curved frame - to block side reflections

The biggest advantage of the curved surface is that it blocks the incoming of ultraviolet rays and strong light in a full range of 360 degrees without dead ends. According to scientific research, about 30% of ultraviolet rays will enter our eyeballs from the side. All-round protection can firmly lock the entry of sunlight.

4. Special mirror coating - waterproof and anti-fog

Anti-staining coating is standard for most sports glasses, which can prevent sweat or rainwater from hanging on the lens and affecting vision. Especially in the hot summer, sweat will inevitably drip onto the lens, and the anti-stain coating instantly makes sweat disappear without a trace.

5. The frame of the easily distorted material - reduce breakage

The equipment for running should be lightweight, and no one will carry a glasses case with them. Usually, the simple and violent method is to throw the sunglasses directly into the bag. In terms of frame materials, sports glasses will choose materials that are easy to twist, so that the frame will not be broken or damaged when the bag is shaken and squeezed.
