WHY A CIVIL ENGINEER MUST WEAR SUNGLASSES AT SITE

A civil  engineer must wear a sun glass while at work site because long-term exposure to the blue and violet portion of the solar spectrum has been implicated as a risk factor. Sun’s brightness and glare interferes with comfortable vision and the ability to see clearly . Wide-brimmed hats and caps can block about 50 percent of uv radiation from the eyes. But optometrists say that is not enough protection. Spending just two or three hours in bright sunlight can hamper the eyes’ ability to adapt quickly to night time or indoor light levels. This can make driving at night after spending a day in the sun more hazardous.

You don’t necessarily need the expensive glasses to block out uv rays. Good sunglasses will give distortion free vision. Not only civil engineers everybody should wear sunglasses outdoors whether they are working, driving, participating in sports, taking a walk, running errands or doing anything in the sun.
Sunglasses should block out 99 to 100 percent of both uva and uvb radiation and screen out 75 to 90 percent of visible light. 90% of people believe that protecting their eyes is key to overall health.
Most sunglasses offer 100% uva and uvb protection.

Look for sunglasses that fully cover your eyes. Wrap-around lenses are even better they block out light and glare from the side & front.

WHY POLARIZED SUNGLASSES ARE BEST

Polarized lenses are the most effective lenses for blocking glare. Polarized sunglasses work by filtering out certain frequencies and orientations of light which is harmful to human eyes. To polarize a material for light, etches of scratches must be microscopically be put into the material. Only the light waves that are lining up with the scratches can pass through. This is the basis behind polarized sunglasses.
