Why Do We Need To Wear Sunglasses In The Fall?

With the arrival of the fall, most people think that the sun is not so strong, so they remove all kinds of sun protection, especially sunglasses to protect the eyes. In fact, it is unscientific because the ultraviolet rays in the fall are more arrogant. Although the intensity of sunlight is not very strong, the intensity of ultraviolet rays does not decrease in proportion to the decrease in temperature. On the contrary, due to the dry weather in autumn, the moisture and clouds in the atmosphere are reduced, so the penetration of ultraviolet rays is enhanced, and the amount of ultraviolet rays reaching the ground is more than in summer, about twice that of summer. Therefore, sun protection in the fall is still indispensable.

The main function of sunglasses is to resist UV rays and protect our eyes, including polarized sunglasses, which are designed do reduce glare and enhance contrast.  UV rays refer to sunlight that is invisible to the human eye. Its damage to the human eye is mainly determined by its wavelength, radiation time, and radiation intensity, and the strength of the human eye's own defense mechanism. The cornea is the most commonly damaged parts of the eyes. Another feature of UV rays is that the damage to the eyes is cumulative. Therefore, it is necessary to wear UV protection sunglasses when going out in the Fall.

According to surveys, in Hawaii, Arizona, New Mexico, Colorado and southern California, UV rays are still strong in the fall and winter because of their high altitudes or low latitudes. People who have been to these cities know that the fall and winter there are sunny and you need to wear sunglasses to block UV rays.

NO.1 Hawaii: Although it is winter, the UV intensity there is still high because it is close to the equator.

NO.2 Arizona: These cities, including Phoenix and Tucson, still have strong sunshine and high UV levels in the fall and winter.

NO.3 New Mexico: High-altitude areas such as Albuquerque and Santa Fe have high UV indexes even in the fall and winter.

NO.4 Colorado: Such as Denver and Colorado Springs, high-altitude mountainous areas increase the intensity of UV rays, especially ski resorts.

NO.5 Southern California: In San Diego and Los Angeles, the sun is still strong in winter.

In the fall, some people will suffer from dry eyes, which include eye pain, tearing, dryness, photophobia, redness and swelling, etc. This also has a lot to do with people ignoring the damage of UV rays. Because the wind is also strong in the fall, the eyes are exposed to the dry environment of wind and sand for a long time, which leads to tear loss. Besides eating more fruits and drinking more water, the other way to protect your eyes is to wear a pair of premium sunglasses. It is recommended to wear polarized sunglasses like Jefoo aviators JF119 or wayfarer style JF129 lightweight sunglasses when going out for outdoor activities. Not only can it protect your eyes, but the colorful shapes will also make you more fashionable in the fall. Many things can be made up and decorated in spring and summer. In the fall frost and winter wind, sunglasses can be regarded as a rare but perfect decoration.
