Purchase Matters Of Sunglasses
Medical experts suggest that when buying sunglasses, you can judge whether the object is clear. To buy high-quality sunglasses, you can go to optical professional stores and regular glasses stores to buy sunglasses.
● The human body has an instinctive reaction of self-protection. When the eyes encounter strong light, the pupil will naturally become smaller, reducing the UV energy entering the eyes. Once wearing glasses without UV protection function, the pupil will be enlarged. In addition, such glasses do not have the function of isolating UV. At this time, the eyes are equal to a wide open door, allowing the UV to enter, and the damage to the eyes can be imagined.
● Sunglasses can block ultraviolet rays because a special coating is added to the lenses. Poor sunglasses can not block ultraviolet rays, but also seriously reduce the lens transmittance, making the pupils larger. Instead, ultraviolet rays will penetrate in large quantities, causing damage to the eyes. In addition, poor quality lenses can also cause vision fatigue symptoms such as nausea, amnesia and insomnia.
● The color of the sunglasses is light gray, brown or light smoke, followed by green, amber, blue, etc., and red is only used for sunbathing or snow.
● It is best to use polarized sunglasses when taking a car, because they can reduce the glare.
● If people can see your eyes clearly after you wear sunglasses, your lenses are too light.
● When the sun goes down, you'd better remove your sunglasses, otherwise our vision will be affected in places with weak light.
● You should go to a regular eyewear store to select sunglasses with UV protection function produced by a regular manufacturer.
● Pay attention to the lens surface when selecting.
● Round frame sunglasses are suitable for people with long and thin faces.
