Sunglasses allow you to protect your eyes from direct sunlight. Typically, their frames are made of synthetic materials like plastic or nylon, but also metal. If we talk about the lenses, the UV blocking levels will vary.
One of the most important tips when you choose sunglasses is that you should opt for a good quality product that allows you to have more protection and that fits completely to the face. In addition, these accessories should protect the eyes from the rays that come from the front and the sides too.
The origin of these accessories was in China in the 12th century, here was the first place where a technology was developed that would allow the quartz crystals to be smoked in order to darken them. At first, these smoked glasses were used by Chinese judges, but at that time, the purpose of these was not to protect the eyes from the sun.
During the 20th century, silent movie stars began to implement the use of sunglasses and in 1929, Sam Foster began a large and inexpensive production of these accessories in the United States.
On the other hand, it should be noted that the visual system is constantly subjected to excessive solar exposures. Ultraviolet radiation and infrared radiation are the types of radiation that produce the largest and most important impact at the ocular level.
The only way to protect the eyes is by wearing sunglasses that protect us from solar radiation that can harm us and cause us discomfort in the future. However, it must be made clear that not all of them are effective, for this reason we have to choose them carefully because some, instead of protecting us, can cause us irreversible damages.
The best option is to go to optical establishments that have an adequate sanitary approval to avoid any inconvenience.

If we want to know what the level of protection of sunglasses is, this will depend on the category of the filter that appears on the rod with a number. This numbering goes from 1 to 5 and indicates the recommended use, going from exceptional brightness to dimmed.
Over time, different studies have been carried out that certify that many of the damages of the eyes are caused by the sun. Ultraviolet radiation affects the macula or central vision area with greater intensity, but a greater exposure to the sun could damage other structures like the cornea and lens.
Depending on the wavelength, light is distinguished between 3: the visible spectrum, the invisible spectrum and the infrared. If we talk about the visible spectrum, we can mention that it is between 400 nm and 700 nm. Currently, some sunglasses protect up to 380 nm but Polaroid or RayBan lenses assure to provide 400 nm protection.
