Skin exposed to excessive amounts of UV (ultraviolet) rays can lead to sunburn, sunburn, aging or even cancer. So is there a way to see the fastest and simplest UV index on a phone? The answer will be answered shortly!
Ultraviolet rays, or ultraviolet rays, are derived from sunlight, meaning that the sun has UV rays. Currently there are 3 different types of UV rays: UVA, UVB and UVC.
In particular, UVB rays are partially reflected by the ozone layer and UVC rays will be blocked almost 100%. Therefore, up to 99% of ultraviolet rays hitting the ground are classified as UVA rays, a small fraction of UVB.
UV rays are also the cause of harmful effects to the skin if exposed for long, such as sunburn, heat stroke, aging or even increase the risk of skin cancer.
The ultraviolet index (UV index) is a measure of international standards for the strength of ultraviolet rays from the sun. The higher the number is, the more dangerous it is, as follows:
