Choose regular channels to buy sunglass near me
It needs to be reminded that some shops, stalls, night markets sold cheap so-called "top brand" sunglasses are not true, often the lens is rough, poor optical performance. The material is not the use of one-time stamping molding resin, but recycled materials, and even the use of more inferior cheap plastic. This kind of sunglasses has almost no effect of shielding ultraviolet light, and the optical performance is very poor, and the prism degree and the top focal degree are often exceeded. Wearing for a long time will lead to vision fatigue, but also easy to have vertigo. Not only does it not protect the eyesight, but it will damage the eyes. If in the case of driving or outdoor sports, it will endanger the personal safety of the wearer. In addition, these businesses often have no reputation protection or mobile sales, and there is no way to protect their rights once there is a problem. Therefore, please pay attention to choose regular manufacturers and regular shops when buying sunglasses to protect your own interests from infringement.
Most children need to wear sunglasses when the sun is strong, because children's cornea and lens are clearer than adults, so ultraviolet rays are easier to shoot into the retina, damage the corneal epithelium, and cause burns to the macular area of the retina. But can not wear for too long, because the child's visual function is not mature, need more bright light and clear image stimulation, long-term wear will affect the normal development of vision, severe can lead to amblyopia. Do not wear them indoors or in a cool place, and choose sunglasses produced by regular manufacturers.
Maintenance and cleaning of sunglasses
Use both hands when putting on or taking off the mirror to avoid deformation of the frame due to long-term unilateral force.
Keep the mirror up and away from the high temperature environment.
Store in a mirror case or bag when not wearing, and keep away from high temperature.
Use a special lens swab to clean the lenses. When the lens is stained with dust or other impurities, rinse with running water before wiping. Dry rubbing can scratch the lens easily. In particular, it should be noted that glasses equipped with polarized lenses cannot be cleaned with ultrasound, otherwise it will destroy the polarizing effect. Sunglasses with diamond or other embellishing frames are also not suitable for ultrasonic cleaning.
Often check the screws, nose clip is loose, if there is a problem should be sent to the optical shop reinforcement.
