The eye is our most important sensory organ. Light enables man to recognize and orient himself to his environment. The positive effects of light occur only within a closely restricted range of the power of light radiation — too much light and radiation damage the eye.
Therefore, it is important to protect the skin and the eyes from all forms of harmful influences.

Damage to the eyes may occur as a result of a variety of extraneous causes. In the case of mechanical and chemical exposure, these are obvious. It is a different matter, however, when it comes to damage caused by optical radiation. This can arise from natural sources the sun or artificial sources hot objects, welding and cutting with burners, when handling laser equipment, when working on electrical installations.
The effects of optical radiation on the eye The penetration depth of optical radiation depends on the wavelength. Whilst shortwave radiation UV radiation and longwave IR radiation are already absorbed on the surface of the skin or the eye, the visible radiation and radiation in the vicinity of the infrared range of the spectrum penetrates deep into the tissue or skin.

But in , a tighter focus on wind speeds went into effect. Today, a Category 1 storm is one with sustained winds of 74 to 95 miles per hour, while a Category 5 storm has sustained wind speeds of m. Most of the area will be uninhabitable for weeks or months. Only a few hurricanes have ever made landfall in the United States as a Category 5 storm.
The last was Andrew , in Take Hurricane Sandy. In , it never made landfall as anything stronger than a Category 2 storm. But it led to flooding, mudslides, power failures and dozens of fatalities in the Caribbean and the United States. Herbert Saffir, a structural engineer, created the scale in It was expanded with help from Robert Simpson, a former director of the National Hurricane Center, and it became known as the Saffir-Simpson scale in the s.
The ranking system once took several factors into consideration, including storm surges and atmospheric pressure. But in , a tighter focus on wind speeds went into effect.
