When to say when
![Secretary of State John Kerry rubs his eyes while testifying on Capitol Hill in Washington, Tuesday, Dec. 10, 2013, before the House Foreign Affairs Committee in the hope of persuading Congress to not forge any new economic sanctions on Iran that could break the recent historic agreement that would end Iran�s progress toward weapons-grade uranium. The deal struck in Geneva prohibits the Obama administration from introducing new sanctions for six months. Iran's foreign minister has said any new package of commercial restrictions would break the agreement. (J.

Many times we have cleaned our glasses or contact lenses and our view of the world has not improved. Hazy skies? No, cataracts. And they are the leading cause of blindness, but also a normal process of aging. The surgery is the most common one performed with over 3 million done each year. Since the cataract growth is gradual, patients often decide when they are ready to have the simple procedure to clear their vision. Unchecked eyes that develop cataracts may eventually cause blindness.
