In light of the dangers associated with UV, the month of May was set as Ultraviolet Awareness month. Studies have shown that 20% of cataract cases are a result of UV rays. Sadly, this number has been rising in recent years.
Ultraviolet radiation refers to the invisible high energy rays that come from the sun. Since they are invisible, our naked eyes cannot see them. Most notably, these rays are UVA, UVB and UVC. Ultraviolet light is measured in a unit known as nanometers (nm) and those three are classified depending on how strong they are.
