...couture debut, Penélope Cruz perused her options for the red carpets at this year's awards ceremonies. Even Vogue editor Anna Wintour was back in town after sitting out the past two spring couture seasons. But those who wanted to see the real action needed to keep an eye on the new faces in the crowd...
...signs that you're not as young as you used to be. But most of us don't think much about how aging--not to mention the desiccating effects of wintry winds and overheating--also dries out the thin film of tears that bathes and protects our eyes. For 10 million Americans, the problem is bad enough that they suffer from something called dry-eye syndrome. Their eyes become dry and itchy or, at the other extreme, produce excessive quantities of tears. Their vision may get blurry, or they may find they can't leave their contacts in for very...
Fortunately, chronically dry eyes can usually be treated. There are dozens of over-the-counter products designed to moisten or lubricate your eyes, but you should resist the temptation to play doctor and instead should seek out an eye-care specialist. Dry eyes may be associated with an underlying medical condition like lupus, rheumatoid arthritis, eczema, a viral infection or something called Sjogren's syndrome, says Dr. Esen Akpek, an ophthalmologist who runs the dry-eye clinic at Johns Hopkins' Wilmer Eye Institute. "You can also overdo it with eyedrops and actually wash out your own tears," Akpek says. Also...
Research over the past decade has shown that the film covering your eyes is quite complicated. There's an inner layer of sugary proteins, followed by a more watery middle layer and then an oily layer on top. Chronic dry eye can result from an imbalance in any part of the film. For example, the oily layer, which is produced by glands at the base of the eyelashes, keeps tears from evaporating too quickly. If you don't make enough oil, you may need one of the thicker over-the-counter eyedrops to bolster that layer, along with warm compresses...
...many scientists--and science teachers--don't think there is any valid criticism. Sure, some 350 scientists have signed a declaration challenging evolution. But many tens of thousands of scientists reject I.D.'s core argument--that evolution can't produce complex structures. Take the eye. I.D. theorists say it could not have evolved bit by bit because a bit of an eye has no survival value; it would never have been passed on. Biologists see it differently. They say, for example, a primitive, light-sensing patch of skin--a forerunner of the retina--could help animals detect the shadows...
