Ultraviolet band is divided into UVA, UVB and UVC. UVA is the UV with a wavelength ranging from 315nm to 400nm, which will tan the skin and cause harm to cornea, or Photokeratitis when the harm is serious; UVB is the UV with a wavelength ranging from 280 to 315nm, which can reach the ground and cause harm to cornea, or Photokeratitis when the harm is serious; UVC has a wavelength ranging from 100 to 280nm and causes no harm to human body, for it is absorbed by the ozonosphere and cannot reach the ground. Therefore, the UV we mention in everyday life refers to UVA and UVB.

UVA/UVB is extremely easy to cause harm to the fine and fragile eye tissues. UV can get in from outside the eyes to cause damage of varying degrees, from conjunctiva, cornea, crystalline lens and vitreum to retina. Excessive exposure of eyes to UV will accelerate the occurrence of cataract and cause 5%~10% of the skin cancer that occurs around the eyelid. The harm of UV for eyes is cumulative and irreversible.

In each year, 40% of the UV contact takes place under inadequate solarization. Even in a completely dark environment, we can still come into contact with substantial UV. Therefore, we should not relax our vigilance on cloudy days or in indoor environment. It is important to make a good job of the protection against UV every day.

People cannot escape from the harm of UV when working either in indoor or outdoor conditions. It is especially important to wear a pair of suitable spectacles. For most people, colored sunglasses are inappropriate for formal occasions.
