Sunglasses are popular in every summer because of the possible fierce sunlight. Since many years ago, sunglasses in different styles have been considered as a fashionable accessory by both celebrities and ordinary individuals. Cool sunglasses suit people of any age. In modern times, sunglasses are thought by many people to be a good fashion statement. This is the most widely recognized benefit offered by sunglasses.
Yet another critical function of sunglasses is the prevention of ultra-violet rays. This benefit from sunglasses is more and more valuable in the background of the depleting layers of ozone in the Earth’s atmosphere. Because of the thinning ozone layers, more and more ultra-violet rays enter the earth. It is well known that excessive UV rays can damage the human skin. In serious cases, even skin cancer will occur. This is the reason why many doctors would advise their patients to wear sunscreen in bright sunshine days.
Skin is not the only organ that may be affected. A more delicate organ is the eye. In fact, the eyes need UV protection more urgently than other organs because good eyesight is so crucial for everyone. This is the key functional benefit of sunglasses that they can protect the eyes from UV rays. In most cases, sunglasses manufactured by different brands have tags which indicate how much UV protection they can offer. A basic requirement when buying sunglasses is to choose the ones that block out at least 99% of all incoming radiation.
All members in a family need UV protection offered by sunglasses. In this sense, sunglasses can not be too safe. It is advisable and feasible to buy different pairs of sunglasses for each family member. In fact, adults and children need different degrees of UV protection. Children’s eyes are more delicate that they need sunglasses in most cases. Moreover, most kids spend much time outdoors where strong sunlight is always present.
