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.
A sunscreen rated as SPF 10 blocks 90% of the sunburn-causing UVB radiation; an SPF20 rated sunscreen blocks 95%. Modern sunscreens contain filters for UVA radiation as well as UVB. Although UVA radiation does not cause sunburn, it does contribute to skin aging and an increased risk of skin cancer.
