Sunglasses are used in the strong sunlight in most cases. They can make your eyes far away from the UV radiation. Excessive exposure to ultraviolent rays from the sun would cause potential eye problems. And young people are more susceptible to the UV radiation because they spend more time on outdoor activities. Therefore, they should prefer to wear sunglasses when they are under the strong sunshine.
In some people's mind, they always think that wearing sunglasses is just for fashion. Sunglasses are a necessary decoration like necklaces, hats. Actually, the function of eyes protection is more important. People's eyes are more susceptible to UV-related skin cancer than other parts of the body, so that extra protection is very essential. Many studies indicate that UV rays cause cataracts and also damage the cornea.
Both direct sunlight and reflected sunlight and UV rays should be paid close attention. When you are near surfaces that reflect UV rays, make sure you have wore sunglasses. Reflective surfaces include water, snow, sand, roadways, and glass and so on. Polarized lenses can selectively block reflected lights with special lens material. Certain medications such as antibiotics make people sensitive to sunlight. In this case, sunglasses are particularly helpful. Sunglasses can not only block UV rays, but also shield your eyes from wind and dust. A pair of non-prescription sunglasses is still needed in some situations.
When choosing a pair of suitable sunglasses, you should pay attention to the UV protection index. The protection index is not related with the prices. You can choose the frame styles on the basis of your tastes. The lenses of sunglasses should be considered carefully. Be sure that there is no distortion throughout the lenses. The colors also should be taken into consideration. If you require acute vision, brown lenses can be your choice. Besides, you need to take darkness of the lens (density) into account. On bright days, dark sunglass lenses are more helpful.
