u003cbru003eAre your
sunglasses really fashionable and suitable for you? Good sun
glasses can effectively block ultraviolet rays and glare, but the shades of the sun lenses are not very helpful in resisting ultraviolet rays. Many countries have regulated the UV absorption rate of
sunglasses. In addition, such as polarizer, anti-reflection film and dyed film, etc., can make
sunglasses better reduce glare, anti-reflection, increase object contrast in foggy and cloudy days, and make the field of vision clear. When buying sunglasses, people are not only looking for beauty, but also want to reduce the damage to the eyes of bright light, harmful ultraviolet (UV) light and glare. YC9702 Ladies Sunglasses C3 Black/Colorful Blue Lenses Factors that affect the quality of glasses too: 1) The light reflected by glare water or smooth surfaces is 10 to 12 times stronger than the light required by the object. When driving or participating in sports activities, glare can cause eye pain, and at the same time distract attention and cause certain dangers. To determine whether sunglasses can block glare, please wear sunglasses and stand in front of the mirror. If you can see your eyes, the sunglasses are not deep enough to resist glare.

Sunglasses that can absorb at least 75% of visible light can prevent the eyes from being damaged by blue light (which belongs to the category of visible light). It is difficult for people to stare at blue light and usually squint. Blue light can distort colors.

But if the sunglasses are loose, it will affect the visual comfort. Mask-type or edge-shielding sunglasses can block ultraviolet light on the sides, top, and bottom of ordinary frames, but they may also increase optical distortion. To test the visual effect, please wear sunglasses, and then look at the vertical edges or straight lines (such as door frames or floor tiles). Move the head back and forth so that the eyes are swept across the lens. If the straight line is found to be curved, it means that the lens is defective and distorts the vision. 4) The tinted lens should be evenly tinted, not small pieces of different shades. If a gradient lens is used, the color of the lens should gradually become lighter from the top to the bottom, and the color should be uniform. If you plan to buy sunglasses for use while driving, check the labels to make sure they meet the requirements for identifying traffic signals. The shading of some sunglasses can distort the color of road signs, especially sunglasses that have a special function of blocking ultraviolet light. You cannot wear such sunglasses while driving.
