Large corporations and individual unions also have offices in the capital. Trade associations represent entire industries. The members of the American Public Power Association (APPA), for example, are municipally owned electric utilities, rural electric cooperatives, and state power authorities. Professionals also form interest groups.
well the UV rays can indeed go through your eyelids, but like the others i've closed my eyes and am fine....if you dont tan 365 days a year for 90 years i dont think you'll be in danger...also one thing to consider is if you wear contacts....most are now UV light protected which definitely helps to block out the rays.
Not all polarization is equal. Because not all polarized sunglasses block glare as well as they should. A polarizing filter is no guarantee of an effective glare-blocking lens. It depends on the quality of the filter and how the lens has been produced.
