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.
Kenneth A. Arndt, MD, clinical professor of Dermatology at Harvard Medical School, Boston, wrote in the current Bottom Line Personal that sunscreen and sunblock are not the same. Sunblock is opaque and blocks almost all of the sun's UVA and UVB rays. It consists largely of zinc oxide and titanium dioxide. Sunblock does not have to be reapplied every few hours. Sunscreens are less visible on the skin and are designed to protect against UVA, UVB, or both.
