The damage of ultraviolet rays to the human body is cumulative. The longer the exposure to the sun, the greater the damage of ultraviolet rays. There is a statistical report in the United States that 80% of the ultraviolet rays that a person is exposed to in his lifetime are accumulated by exposure to sunlight before the age of eighteen.style of sunglasses

 Therefore, to avoid the damage of ultraviolet rays, one must start from a young age.

To avoid damage to the eyes caused by ultraviolet rays, it is of course necessary to minimize exposure to strong sunlight, especially between 10 am and 2 pm, when the sun is directly on the surface of the earth and the ultraviolet intensity is the highest. Especially those ultraviolet rays reflected from cement, snow, beach or water are the most powerful and cause the most damage to the eyes, but they are the easiest to be ignored. Therefore, if you want to be active in these places for a long time, remember to wear appropriate polarized sunglasses.

Of course, if you are a car owner who needs to drive, it is better to wear polarized sunglasses when driving, because driving often encounters various glare, polarized sunglasses can block part of the glare, but also filter out the ground or The strong light reflected from the opposite car body makes the vision clearer, reduces visual fatigue, and is conducive to safe driving.

Note: It is best to confirm that the lens can effectively block more than 99% of ultraviolet rays (including ultraviolet A and ultraviolet B), and at the same time have polarizing characteristics.

Sunglasses are not only required to be worn in summer, in fact they must be used throughout the year. Wear it on sunny days and also on cloudy days. Don't think that the sun is not strong on cloudy days and the weather is not hot. Just take it lightly and unknowingly expose it to more harmful ultraviolet rays. Therefore, even if it is a cloudy day with thin clouds, you must still refer to the UV index forecast and be prepared for sun protection.
